protected void	_writePPFieldName(SerializableString name, boolean commaBefore)
protected void	_writePPFieldName(String name, boolean commaBefore) 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.
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).
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(SerializedString 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	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 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(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	writeStringField(String fieldName, String value) Convenience method for outputting a field entry ("member") that has 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).

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

Description copied from class: JsonGenerator

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.

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.

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 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). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

                 throws IOException,
                        JsonGenerationException

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.

writeNumber

public void writeNumber(String encodedValue)
                 throws IOException,

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.

                      JsonGenerationException

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

JsonGenerationException

_verifyValueWrite

protected final void _verifyValueWrite(String typeMsg)
                                throws IOException,
                                       JsonGenerationException

protected final void _verifyPrettyValueWrite(String typeMsg,
                                             int status)

JsonGenerationException

flush

public final 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 class JsonGeneratorBase

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

Overrides:

close in class JsonGeneratorBase

Throws:

IOException
