```
public void setSchema(FormatSchema schema)
```
    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.
    
    Parameters:
    schema - Schema to use
    
    Throws:
    
    UnsupportedOperationException - if generator does not support schema
  - getSchema
```

    Method for accessing Schema that this parser uses, if any. Default implementation returns null.
    
    Since:
    
    2.1
  - setPrettyPrinter
```
public JsonGenerator setPrettyPrinter(PrettyPrinter pp)
```
    Method for setting a custom pretty printer, which is usually used to add indentation for improved human readability. By default, generator does not do pretty printing.
    To use the default pretty printer that comes with core Jackson distribution, call useDefaultPrettyPrinter() instead.
    
    Returns:
    Generator itself (this), to allow chaining
  - getPrettyPrinter
```
public PrettyPrinter getPrettyPrinter()
```
    Accessor for checking whether this generator has a configured PrettyPrinter; returns it if so, null if none configured.
    
    Since:
    
    2.1
  - useDefaultPrettyPrinter
```
public abstract JsonGenerator useDefaultPrettyPrinter()
```
    Convenience method for enabling pretty-printing using the default pretty printer (DefaultPrettyPrinter).
    
    Returns:
    Generator itself (this), to allow chaining
  - setHighestNonEscapedChar
```
public JsonGenerator setHighestNonEscapedChar(int charCode)
```
    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.
    
    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()
```
    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.
    
    Returns:
    Currently active limitation for highest non-escaped character, if defined; or -1 to indicate no additional escaping is performed.
  - getCharacterEscapes
```
public CharacterEscapes getCharacterEscapes()
```
    Method for accessing custom escapes factory uses for JsonGenerators it creates.
  - setCharacterEscapes
```
public JsonGenerator setCharacterEscapes(CharacterEscapes esc)
```
    Method for defining custom escapes factory uses for JsonGenerators it creates.
    Default implementation does nothing and simply returns this instance.
  - setRootValueSeparator
```
public JsonGenerator setRootValueSeparator(SerializableString sep)
```
    Method that allows overriding String used for separating root-level JSON values (default is single space character)
    Default implementation throws UnsupportedOperationException.
    
    Parameters:
    sep - Separator to use, if any; null means that no separator is automatically added
    Since:
    
    2.1
  - getOutputTarget
```
public Object getOutputTarget()
```
    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.
  - getOutputBuffered
```
public int getOutputBuffered()
```
    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)
    
    Returns:
    Amount of content buffered in internal units, if amount known and accessible; -1 if not accessible.
    Since:
    
    2.6
  - getCurrentValue
```
public Object getCurrentValue()
```
    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.
    
    Since:
    
    2.5
  - setCurrentValue
```
public void setCurrentValue(Object v)
```
    Helper method, usually equivalent to: getOutputContext().setCurrentValue(v);
    
    Since:
    
    2.5
  - canUseSchema
```
public boolean canUseSchema(FormatSchema schema)
```
    Method that can be used to verify that given schema can be used with this generator (using setSchema(com.fasterxml.jackson.core.FormatSchema)).
    
    Parameters:
    schema - Schema to check
    
    Returns:
    True if this generator can use given schema; false if not
  - canWriteObjectId
```
public boolean canWriteObjectId()
```
    Introspection method that may be called to see if the underlying data format supports some kind of Object Ids natively (many do not; for example, JSON doesn't). This method must be called prior to calling writeObjectId(java.lang.Object) or 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.
    
    Since:
    
    2.3
  - canWriteTypeId
```
public boolean canWriteTypeId()
```
    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 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.
    
    Since:
    
    2.3
  - canWriteBinaryNatively
```
public boolean canWriteBinaryNatively()
```
    Introspection method that may be called to see if the underlying data format supports "native" binary data; that is, an efficient output of binary content without encoding.
    Default implementation returns false; overridden by data formats that do support native binary content.
    
    Since:
    
    2.3
  - canOmitFields
```
public boolean canOmitFields()
```
    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.

                              throws IOException
```
    Method for writing starting marker of a Array value (for JSON this is character '['; plus possible white space decoration if pretty-printing is enabled).

    IOException
  - writeStartArray
```
public void writeStartArray(int size)
                     throws IOException
```
    Method for writing start marker of an Array value, similar to writeStartArray(), but also specifying how many elements will be written for the array before calling writeEndArray().
    Default implementation simply calls writeStartArray().
    
    Parameters:

                               throws IOException
```
    Method for writing starting marker of a JSON Object value (character '{'; plus possible white space decoration if pretty-printing is enabled).
    Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

    Method for writing closing marker of a JSON Object value (character '}'; plus possible white space decoration if pretty-printing is enabled).
    Marker can be written if the innermost structured type is Object, and the last written event was either a complete value, or START-OBJECT marker (see JSON specification for more details).

public abstract void writeFieldName(String name)
                             throws IOException
```
    Method for writing a field name (JSON String surrounded by double quotes: syntactically identical to a JSON String value), possibly decorated by white space if pretty-printing is enabled.
    Field names can only be written in Object context (check out JSON specification for details), when field name is expected (field names alternate with values).

```
public abstract void writeFieldName(SerializableString name)
                             throws IOException
```
    Method similar to 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.

public abstract void writeString(String text)
                          throws IOException

public abstract void writeString(SerializableString text)
                          throws IOException
```
    Method similar to writeString(String), but that takes SerializableString which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.
    Default implementation just calls writeString(String); sub-classes should override it with more efficient implementation if possible.

                                 throws IOException
```
    Method similar to 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.

```
    Method similar to 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. In this case generator implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

```
    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.
    
    Parameters:
    bv - 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.

public abstract void writeNumber(String encodedValue)
                          throws IOException
```
    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 writeString(java.lang.String) method can not be used; nor 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.
    
    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)

    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.

public final void writeArrayFieldStart(String fieldName)
                                throws IOException
```
    Convenience method for outputting a field entry ("member") (that will contain a JSON Array value), and the START_ARRAY marker. Equivalent to:
```
  writeFieldName(fieldName);
  writeStartArray();
```
    Note: caller still has to take care to close the array (by calling {#link #writeEndArray}) after writing all values of the value Array.
    Throws:
    
    IOException
  - writeObjectFieldStart
```
public final void writeObjectFieldStart(String fieldName)
                                 throws IOException
```
    Convenience method for outputting a field entry ("member") (that will contain a JSON Object value), and the START_OBJECT marker. Equivalent to:
```
  writeFieldName(fieldName);
  writeStartObject();
```
    Note: caller still has to take care to close the Object (by calling {#link #writeEndObject}) after writing all entries of the value Object.
    Throws:
    
    IOException
  - writeObjectField
```
public final void writeObjectField(String fieldName,
                    Object pojo)
                            throws IOException
```
    Convenience method for outputting a field entry ("member") that has contents of specific Java object as its value. Equivalent to:
```
  writeFieldName(fieldName);
  writeObject(pojo);
```
    Throws:
    
    IOException
  - writeOmittedField
```
public void writeOmittedField(String fieldName)
                       throws IOException
```
    Method called to indicate that a property in this position was skipped. It is usually only called for generators that return false from canOmitFields().
    Default implementation does nothing.
    
    Throws:
    
    IOException

  - copyCurrentEvent
```
public void copyCurrentEvent(JsonParser jp)
                      throws IOException
```
    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)
    
    Throws:
    
    IOException
  - copyCurrentStructure
```
public void copyCurrentStructure(JsonParser jp)
                          throws IOException
```
    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.
    Throws:
    
    IOException
  - getOutputContext
```
public abstract JsonStreamContext getOutputContext()
```
    Returns:
    Context object that can give information about logical position within generated json content.
  - flush
```
public abstract void flush()
                    throws IOException
```
    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
    
    Throws:
    
    IOException
  - isClosed
```
public abstract boolean isClosed()
```
    Method that can be called to determine whether this generator is closed or not. If it is closed, no more output can be done.
  - close
```
public abstract void close()
                    throws IOException
```
    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
    
    Throws:
    
    IOException
  - _reportError
```
protected void _reportError(String msg)
                     throws JsonGenerationException
```
    Helper method used for constructing and throwing JsonGenerationException with given base message.
    Note that sub-classes may override this method to add more detail or use a JsonGenerationException sub-class.
    
    Throws:
    
    JsonGenerationException
  - _throwInternal
```
protected final void _throwInternal()
```
  - _reportUnsupportedOperation
```
protected void _reportUnsupportedOperation()
```
  - _writeSimpleObject
```
protected void _writeSimpleObject(Object value)
                           throws IOException
```
    Helper method to try to call appropriate write method for given untyped Object. At this point, no structural conversions should be done, only simple basic types are to be coerced as necessary.
    
    Parameters:
    value - Non-null value to write
    
    Throws:
    
    IOException
