`protected void`	`_flushBuffer()`
`protected void`	`_outputSurrogates(int surr1, int surr2)`
`protected void`	`_releaseBuffers()` Method called to release any buffers generator may be holding, once generator is being closed.
`protected void`	`_verifyPrettyValueWrite(String typeMsg, int status)`
`protected void`	`_verifyValueWrite(String typeMsg)` Method called before trying to write a value (scalar or structured), to verify that this is legal in current output state, as well as to output separators if and as necessary.
`protected void`	`_writeBinary(Base64Variant b64variant, byte[] input, int inputPtr, int inputEnd)`
`protected int`	`_writeBinary(Base64Variant b64variant, InputStream data, byte[] readBuffer)`
`protected int`	`_writeBinary(Base64Variant b64variant, InputStream data, byte[] readBuffer, int bytesLeft)`
`protected void`	`_writePPFieldName(SerializableString name)`
`protected void`	`_writePPFieldName(String name)` Specialized version of `_writeFieldName`, off-lined to keep the "fast path" as simple (and hopefully fast) as possible.
`void`	`close()` Method called to close this generator, so that no more content can be written.
`void`	`flush()` Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.
`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.
`void`	`writeBinary(Base64Variant b64variant, byte[] data, int offset, int len)` Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes).
`int`	`writeBinary(Base64Variant b64variant, InputStream data, int dataLength)` Method similar to `JsonGenerator.writeBinary(Base64Variant,byte[],int,int)`, but where input is provided through a stream, allowing for incremental writes without holding the whole input in memory.
`void`	`writeBoolean(boolean state)` Method for outputting literal Json boolean value (one of Strings 'true' and 'false').
`void`	`writeEndArray()` Method for writing closing marker of a JSON Array value (character ']'; plus possible white space decoration if pretty-printing is enabled).
`void`	`writeEndObject()` Method for writing closing marker of a JSON Object value (character '}'; plus possible white space decoration if pretty-printing is enabled).
`void`	`writeFieldName(SerializableString name)` 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.
`void`	`writeFieldName(String name)` 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.
`void`	`writeNull()` Method for outputting literal Json null value.
`void`	`writeNumber(BigDecimal value)` Method for outputting indicate Json numeric value.
`void`	`writeNumber(BigInteger value)` Method for outputting given value as Json number.

`void`	`writeNumber(long l)` Method for outputting given value as Json number.
`void`	`writeNumber(short s)` Method for outputting given value as Json number.
`void`	`writeNumber(String encodedValue)` Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types.
`void`	`writeRaw(char ch)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRaw(char[] cbuf, int offset, int len)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRaw(SerializableString text)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRaw(String text)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRaw(String text, int offset, int len)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRawUTF8String(byte[] text, int offset, int length)` 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).
`void`	`writeStartArray()` Method for writing starting marker of a Array value (for JSON this is character '['; plus possible white space decoration if pretty-printing is enabled).
`void`	`writeStartObject()` Method for writing starting marker of a JSON Object value (character '{'; plus possible white space decoration if pretty-printing is enabled).
`void`	`writeString(char[] text, int offset, int len)` Method for outputting a String value.
`void`	`writeString(SerializableString text)` Method similar to `JsonGenerator.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.
`void`	`writeString(String text)` Method for outputting a String value.
`void`	`writeUTF8String(byte[] text, int offset, int len)` 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).

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.

```
public void writeFieldName(String name)
                    throws IOException
```
    Description copied from class: JsonGenerator
    
    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).

    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.

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.

```
    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:
    
    writeBinary in class JsonGenerator
    
    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.
    
    Returns:
    Number of bytes read from data and written as binary payload

```
    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.

```
    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.
