 void close()
          Method called to close this generator, so that no more content can be written.
 void flush()

          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)

 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.

          Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types.

 void writeString(String text)
          Method for outputting a String value.
 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)

                                   JsonGenerationException
Description copied from class: JsonGenerator
Convenience method for outputting a field entry ("member") that has a String value. Equivalent to:

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).

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.

                 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.
Throws:
IOException

Method for outputting indicate Json numeric 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.

writeNumber

public void writeNumber(String encodedValue)
                 throws IOException,
                        JsonGenerationException
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 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.

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.
