  - getCurrentValue
```
public Object getCurrentValue()
```
    Description copied from class: JsonGenerator
    
    Helper method, usually equivalent to: getOutputContext().getCurrentValue();
    Note that "current value" is NOT populated (or used) by Streaming parser; it is only used by higher-level data-binding functionality. The reason it is included here is that it can be stored and accessed hierarchically, and gets passed through data-binding.
    
    Overrides:
    
    getCurrentValue in class JsonGenerator
  - setCurrentValue
```
public void setCurrentValue(Object v)

    Description copied from class: JsonGenerator
    
    Method for accessing the object used for writing Java object as JSON content (using method JsonGenerator.writeObject(java.lang.Object)).
    
    Specified by:
    
    getCodec in class JsonGenerator
  - setCodec
```
public JsonGenerator setCodec(ObjectCodec oc)
```
    Description copied from class: JsonGenerator
    
    Method that can be called to set or reset the object to use for writing Java objects as JsonContent (using method JsonGenerator.writeObject(java.lang.Object)).
    
    Specified by:
    
    setCodec in class JsonGenerator
    
    Returns:
    
    Generator itself (this), to allow chaining
  - setSchema
```
public void setSchema(FormatSchema schema)
```
    Description copied from class: JsonGenerator
    
    Method to call to make this generator use specified schema. Method must be called before generating any content, right after instance has been created. Note that not all generators support schemas; and those that do usually only accept specific types of schemas: ones defined for data format this generator produces.
    If generator does not support specified schema, UnsupportedOperationException is thrown.
    
    Overrides:
    
    setSchema in class JsonGenerator
    
    Parameters:
    
    schema - Schema to use
  - getSchema
```
public FormatSchema getSchema()
```
    Description copied from class: JsonGenerator
    
    Method for accessing Schema that this parser uses, if any. Default implementation returns null.

  - version
```
public Version version()
```
    Description copied from class: JsonGenerator
    
    Accessor for finding out version of the bundle that provided this generator instance.

    version in interface Versioned
    
    Specified by:
    
    version in class JsonGenerator
  - getOutputTarget
```
public Object getOutputTarget()
```
    Description copied from class: JsonGenerator
    
    Method that can be used to get access to object that is used as target for generated output; this is usually either OutputStream or Writer, depending on what generator was constructed with. Note that returned value may be null in some cases; including case where implementation does not want to exposed raw source to caller. In cases where output has been decorated, object returned here is the decorated version; this allows some level of interaction between users of generator and decorator object.
    In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.
    
    Overrides:
    
    getOutputTarget in class JsonGenerator
  - getOutputBuffered
```
public int getOutputBuffered()
```
    Description copied from class: JsonGenerator
    
    Method for verifying amount of content that is buffered by generator but not yet flushed to the underlying target (stream, writer), in units (byte, char) that the generator implementation uses for buffering; or -1 if this information is not available. Unit used is often the same as the unit of underlying target (that is, `byte` for OutputStream, `char` for Writer), but may differ if buffering is done before encoding. Default JSON-backed implementations do use matching units.
    Note: non-JSON implementations will be retrofitted for 2.6 and beyond; please report if you see -1 (missing override)
    
    Overrides:
    
    getOutputBuffered in class JsonGenerator
    
    Returns:
    
    Amount of content buffered in internal units, if amount known and accessible; -1 if not accessible.

  - canWriteTypeId
```
public boolean canWriteTypeId()
```
    Description copied from class: JsonGenerator
    
    Introspection method that may be called to see if the underlying data format supports some kind of Type Ids natively (many do not; for example, JSON doesn't). This method must be called prior to calling JsonGenerator.writeTypeId(java.lang.Object).
    Default implementation returns false; overridden by data formats that do support native Type Ids. Caller is expected to either use a non-native notation (explicit property or such), or fail, in case it can not use native type ids.

This method must be called prior to calling JsonGenerator.writeObjectId(java.lang.Object) or JsonGenerator.writeObjectRef(java.lang.Object).
    Default implementation returns false; overridden by data formats that do support native Object Ids. Caller is expected to either use a non-native notation (explicit property or such), or fail, in case it can not use native object ids.

```
public boolean canOmitFields()
```
    Description copied from class: JsonGenerator
    
    Introspection method to call to check whether it is ok to omit writing of Object fields or not. Most formats do allow omission, but certain positional formats (such as CSV) require output of placeholders, even if no real values are to be emitted.

public JsonGenerator setPrettyPrinter(PrettyPrinter pp)
```
    Description copied from class: JsonGenerator

    To use the default pretty printer that comes with core Jackson distribution, call JsonGenerator.useDefaultPrettyPrinter() instead.
    
    Overrides:
    
    setPrettyPrinter in class JsonGenerator
    
    Returns:
    
    Generator itself (this), to allow chaining
  - getPrettyPrinter
```
public PrettyPrinter getPrettyPrinter()
```
    Description copied from class: JsonGenerator

  - setHighestNonEscapedChar
```
public JsonGenerator setHighestNonEscapedChar(int charCode)
```
    Description copied from class: JsonGenerator
    
    Method that can be called to request that generator escapes all character codes above specified code point (if positive value); or, to not escape any characters except for ones that must be escaped for the data format (if -1). To force escaping of all non-ASCII characters, for example, this method would be called with value of 127.
    Note that generators are NOT required to support setting of value higher than 127, because there are other ways to affect quoting (or lack thereof) of character codes between 0 and 127. Not all generators support concept of escaping, either; if so, calling this method will have no effect.
    Default implementation does nothing; sub-classes need to redefine it according to rules of supported data format.
    
    Overrides:
    
    setHighestNonEscapedChar in class JsonGenerator
    
    Parameters:
    
    charCode - Either -1 to indicate that no additional escaping is to be done; or highest code point not to escape (meaning higher ones will be), if positive value.
  - getHighestEscapedChar
```
public int getHighestEscapedChar()
```
    Description copied from class: JsonGenerator
    
    Accessor method for testing what is the highest unescaped character configured for this generator. This may be either positive value (when escaping configuration has been set and is in effect), or 0 to indicate that no additional escaping is in effect. Some generators may not support additional escaping: for example, generators for binary formats that do not use escaping should simply return 0.
    
    Overrides:
    
    getHighestEscapedChar in class JsonGenerator
    
    Returns:
    
    Currently active limitation for highest non-escaped character, if defined; or 0 to indicate no additional escaping is performed.

    Method for writing starting marker of an Object value to represent the given Java Object value. Argument is offered as metadata, but more importantly it should be assigned as the "current value" for the Object content that gets constructed and initialized. In addition, caller knows number of key/value pairs ("properties") that will get written for the Object value: this is relevant for some format backends (but not, as an example, for JSON).

    Description copied from class: JsonGenerator
    
    Method similar to JsonGenerator.writeFieldName(String), main difference being that it may perform better as some of processing (such as quoting of certain characters, or encoding into external encoding if supported by generator) can be done just once and reused for later calls.
    Default implementation simple uses unprocessed name container in serialized String; implementations are strongly encouraged to make use of more efficient methods argument object has.

    Description copied from class: JsonGenerator
    
    Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String that is to be output as-is, without additional escaping (type of which depends on data format; backslashes for JSON). However, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.
    Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. If so, implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

    Description copied from class: JsonGenerator
    
    Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String which has not been escaped using whatever escaping scheme data format requires (for JSON that is backslash-escaping for control characters and double-quotes; for other formats something else). This means that textual JSON backends need to check if value needs JSON escaping, but otherwise can just be copied as is to output. Also, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.
    Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding.

```
    Description copied from class: JsonGenerator
    
    Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaults
    Note: because JSON Strings can not contain unescaped linefeeds, if linefeeds are included (as per last argument), they must be escaped. This adds overhead for decoding without improving readability. Alternatively if linefeeds are not included, resulting String value may violate the requirement of base64 RFC which mandates line-length of 76 characters and use of linefeeds. However, all JsonParser implementations are required to accept such "long line base64"; as do typical production-level base64 decoders.
    
    Specified by:

    Parameters:
    
    b64variant - Base64 variant to use: defines details such as whether padding is used (and if so, using which character); what is the maximum line length before adding linefeed, and also the underlying alphabet to use.

    dataLength - (optional) number of bytes that will be available; or -1 to be indicate it is not known. If a positive length is given, data MUST provide at least that many bytes: if not, an exception will be thrown. Note that implementations need not support cases where length is not known in advance; this depends on underlying data format: JSON output does NOT require length, other formats may.

public void writeNumber(String encodedValue)
                 throws IOException,
                        UnsupportedOperationException
```
    Description copied from class: JsonGenerator
    
    Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types. Because numbers are not surrounded by double quotes, regular JsonGenerator.writeString(java.lang.String) method can not be used; nor JsonGenerator.writeRaw(java.lang.String) because that does not properly handle value separators needed in Array or Object contexts.
    Note: because of lack of type safety, some generator implementations may not be able to implement this method. For example, if a binary JSON format is used, it may require type information for encoding; similarly for generator-wrappers around Java objects or JSON nodes. If implementation does not implement this method, it needs to throw UnsupportedOperationException.
    
    Specified by:
    
    writeNumber in class JsonGenerator
    
    Throws:
    
    UnsupportedOperationException - If underlying data format does not support numbers serialized textually AND if generator is not allowed to just output a String instead (Schema-based formats may require actual number, for example)
    
    IOException
  - writeBoolean
```
public void writeBoolean(boolean state)
                  throws IOException
```
    Description copied from class: JsonGenerator
    
    Method for outputting literal JSON boolean value (one of Strings 'true' and 'false'). Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.
    
    Specified by:
    
    writeBoolean in class JsonGenerator
    
    Throws:
    
    IOException
  - writeNull
```
public void writeNull()
               throws IOException
```
    Description copied from class: JsonGenerator
    
    Method for outputting literal JSON null value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.
    
    Specified by:
    
    writeNull in class JsonGenerator
    
    Throws:
    
    IOException
  - writeOmittedField
```
public void writeOmittedField(String fieldName)
                       throws IOException
```
    Description copied from class: JsonGenerator
    
    Method called to indicate that a property in this position was skipped. It is usually only called for generators that return false from JsonGenerator.canOmitFields().
    Default implementation does nothing.
    
    Overrides:
    
    writeOmittedField in class JsonGenerator
    
    Throws:
    
    IOException
  - writeObjectId
```
public void writeObjectId(Object id)
                   throws IOException
```
    Description copied from class: JsonGenerator
    
    Method that can be called to output so-called native Object Id. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.
    
    Overrides:
    
    writeObjectId in class JsonGenerator
    
    Throws:
    
    IOException
  - writeObjectRef
```
public void writeObjectRef(Object id)
                    throws IOException
```
    Description copied from class: JsonGenerator
    
    Method that can be called to output references to native Object Ids. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.
    
    Overrides:
    
    writeObjectRef in class JsonGenerator
    
    Throws:
    
    IOException
  - writeTypeId
```
public void writeTypeId(Object id)
                 throws IOException
```
    Description copied from class: JsonGenerator
    
    Method that can be called to output so-called native Type Id. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteTypeId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.
    
    Overrides:
    
    writeTypeId in class JsonGenerator
    
    Throws:
    
    IOException
  - writeEmbeddedObject
```
public void writeEmbeddedObject(Object object)
                         throws IOException
```
    Description copied from class: JsonGenerator
    
    Method that can be called on backends that support passing opaque datatypes of non-JSON formats
    
    Overrides:
    
    writeEmbeddedObject in class JsonGenerator
    
    Throws:
    
    IOException
  - writeObject
```
public void writeObject(Object pojo)
                 throws IOException
```
    Description copied from class: JsonGenerator
    
    Method for writing given Java object (POJO) as Json. Exactly how the object gets written depends on object in question (ad on codec, its configuration); for most beans it will result in JSON Object, but for others JSON Array, or String or numeric value (and for nulls, JSON null literal. NOTE: generator must have its object codec set to non-null value; for generators created by a mapping factory this is the case, for others not.
    
    Specified by:
    
    writeObject in class JsonGenerator
    
    Throws:
    
    IOException
  - writeTree
```
public void writeTree(TreeNode tree)
               throws IOException
```
    Description copied from class: JsonGenerator
    
    Method for writing given JSON tree (expressed as a tree where given JsonNode is the root) using this generator. This will generally just call JsonGenerator.writeObject(java.lang.Object) with given node, but is added for convenience and to make code more explicit in cases where it deals specifically with trees.
    
    Specified by:
    
    writeTree in class JsonGenerator
    
    Throws:
    
    IOException
  - copyCurrentEvent
```
public void copyCurrentEvent(JsonParser p)
                      throws IOException
```
    Description copied from class: JsonGenerator
    
    Method for copying contents of the current event that the given parser instance points to. Note that the method will not copy any other events, such as events contained within JSON Array or Object structures.
    Calling this method will not advance the given parser, although it may cause parser to internally process more data (if it lazy loads contents of value events, for example)
    
    Overrides:
    
    copyCurrentEvent in class JsonGenerator
    
    Throws:
    
    IOException
  - copyCurrentStructure
```
public void copyCurrentStructure(JsonParser p)
                          throws IOException
```
    Description copied from class: JsonGenerator
    Method for copying contents of the current event and following events that it encloses the given parser instance points to.
    So what constitutes enclosing? Here is the list of events that have associated enclosed events that will get copied:
    - JsonToken.START_OBJECT: all events up to and including matching (closing) JsonToken.END_OBJECT will be copied
    - JsonToken.START_ARRAY all events up to and including matching (closing) JsonToken.END_ARRAY will be copied
    - JsonToken.FIELD_NAME the logical value (which can consist of a single scalar value; or a sequence of related events for structured types (JSON Arrays, Objects)) will be copied along with the name itself. So essentially the whole field entry (name and value) will be copied.
    After calling this method, parser will point to the last event that was copied. This will either be the event parser already pointed to (if there were no enclosed events), or the last enclosed event copied.
    Overrides:
    
    copyCurrentStructure in class JsonGenerator
    
    Throws:
    
    IOException
  - getOutputContext
```
public JsonStreamContext getOutputContext()
```
    Specified by:
    
    getOutputContext in class JsonGenerator
    
    Returns:
    
    Context object that can give information about logical position within generated json content.
  - flush
```
public void flush()
           throws IOException
```
    Description copied from class: JsonGenerator
    
    Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.
    
    Specified by:
    
    flush in interface Flushable
    
    Specified by:
    
    flush in class JsonGenerator
    
    Throws:
    
    IOException
  - close
```
public void close()
           throws IOException
```
    Description copied from class: JsonGenerator
    
    Method called to close this generator, so that no more content can be written.
    Whether the underlying target (stream, writer) gets closed depends on whether this generator either manages the target (i.e. is the only one with access to the target -- case if caller passes a reference to the resource such as File, but not stream); or has feature JsonGenerator.Feature.AUTO_CLOSE_TARGET enabled. If either of above is true, the target is also closed. Otherwise (not managing, feature not enabled), target is not closed.
    
    Specified by:
    
    close in interface Closeable
    
    Specified by:
    
    close in interface AutoCloseable
    
    Specified by:
    
    close in class JsonGenerator
    
    Throws:
    
    IOException
  - isClosed
```
public boolean isClosed()
```
    Description copied from class: JsonGenerator
    
    Method that can be called to determine whether this generator is closed or not. If it is closed, no more output can be done.
