Method

void	close() Method called to close this generator, so that no more content can be written.
JsonGenerator	configure(Feature f, boolean state) Method for enabling or disabling specified feature: check Feature for list of available features.
void	copyCurrentEvent(JsonParser jp) Method for copying contents of the current event that the given parser instance points to.
void	copyCurrentStructure(JsonParser jp) Method for copying contents of the current event and following events that it encloses the given parser instance points to.
JsonGenerator	disable(Feature f) Method for disabling specified features (check Feature for list of features)
void	flush() Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.
Class	getClass() Returns the runtime class of this Object .
ObjectCodec	getCodec() Method for accessing the object used for writing Java object as Json content (using method #writeObject ).
JsonStreamContext	getOutputContext()
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.
PrettyPrinter	getPrettyPrinter() Accessor for checking whether this generator has a configured PrettyPrinter ; returns it if so, null if none configured.
boolean	isClosed() Method that can be called to determine whether this generator is closed or not.
JsonGenerator	setCharacterEscapes(CharacterEscapes esc) Method for defining custom escapes factory uses for JsonGenerator s it creates.
JsonGenerator	setCodec(ObjectCodec oc) Method that can be called to set or reset the object to use for writing Java objects as JsonContent (using method #writeObject ).
JsonGenerator	setPrettyPrinter(PrettyPrinter pp) Method for setting a custom pretty printer, which is usually used to add indentation for improved human readability.
JsonGenerator	useDefaultPrettyPrinter() Convenience method for enabling pretty-printing using the default pretty printer ( com.fasterxml.jackson.core.util.DefaultPrettyPrinter ).
void	writeArrayFieldStart(String fieldName) Convenience method for outputting a field entry ("member") (that will contain a JSON Array value), and the START_ARRAY marker.
void	writeBinary(byte[] data, int offset, int len) Similar to #writeBinary(Base64Variant,byte[],int,int) , but default to using the Jackson default Base64 variant (which is Base64Variants#MIME_NO_LINEFEEDS ).
int	writeBinary(Base64Variant b64variant, InputStream data, int dataLength) Method similar to #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	writeBinary(byte[] data) Similar to #writeBinary(Base64Variant,byte[],int,int) , but assumes default to using the Jackson default Base64 variant (which is Base64Variants#MIME_NO_LINEFEEDS ).
void	writeBinaryField(String fieldName, byte[] data) Convenience method for outputting a field entry ("member") that contains specified data in base64-encoded form.
void	writeBoolean(boolean state) Method for outputting literal Json boolean value (one of Strings 'true' and 'false').
void	writeBooleanField(String fieldName, boolean value) Convenience method for outputting a field entry ("member") that has a boolean value.
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(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	writeFieldName(SerializableString name) 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.
void	writeNull() Method for outputting literal Json null value.
void	writeNullField(String fieldName) Convenience method for outputting a field entry ("member") that has JSON literal value null.
void	writeNumber(short v) Method for outputting given value as Json number.
void	writeNumber(int v) Method for outputting given value as Json number.
void	writeNumber(long v) Method for outputting given value as Json number.
void	writeNumber(BigInteger v) Method for outputting given value as Json number.
void	writeNumber(double d) Method for outputting indicate Json numeric value.
void	writeNumber(float f) Method for outputting indicate Json numeric value.
void	writeNumber(BigDecimal dec) Method for outputting indicate Json numeric value.
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	writeNumberField(String fieldName, int value) Convenience method for outputting a field entry ("member") that has the specified numeric value.
void	writeNumberField(String fieldName, long value) Convenience method for outputting a field entry ("member") that has the specified numeric value.
void	writeNumberField(String fieldName, double value) Convenience method for outputting a field entry ("member") that has the specified numeric value.
void	writeNumberField(String fieldName, float value) Convenience method for outputting a field entry ("member") that has the specified numeric value.
void	writeNumberField(String fieldName, BigDecimal value) Convenience method for outputting a field entry ("member") that has the specified numeric value.
void	writeObject(Object pojo) Method for writing given Java object (POJO) as Json.
void	writeObjectField(String fieldName, Object pojo) Convenience method for outputting a field entry ("member") that has contents of specific Java object as its value.
void	writeObjectFieldStart(String fieldName) Convenience method for outputting a field entry ("member") (that will contain a JSON Object value), and the START_OBJECT marker.
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(char c) 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 raw) 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	writeRawValue(String text) Method that will force generator to copy input text verbatim without any modifications, but assuming it must constitute a single legal JSON value (number, string, boolean, null, Array or List).
void	writeStartArray() Method for writing starting marker of a JSON Array value (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(String text) Method for outputting a String value.
void	writeString(SerializableString text) 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.
void	writeStringField(String fieldName, String value) Convenience method for outputting a field entry ("member") that has a String value.
void	writeTree(TreeNode rootNode) Method for writing given JSON tree (expressed as a tree where given JsonNode is the root) using this generator.
void	writeUTF8String(byte[] text, int offset, int length) 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).
