Method Details

toStream

public static JsonWriter toStream(OutputStream stream)

Creates a DefaultJsonWriter that writes the given OutputStream.

The passed OutputStream won't be closed when close() is called as the DefaultJsonWriter isn't the owner of the stream.

Parameters:

stream - The OutputStream that will be written.

Returns:

An instance of DefaultJsonWriter.

Throws:

UncheckedIOException - If a DefaultJsonWriter wasn't able to be constructed from the OutputStream.

flush

public JsonWriter flush()

Description copied from class: JsonWriter

Flushes any un-flushed content written to this writer.

It should be assumed that each write call won't flush any contents.

Specified by:

flush in class JsonWriter

Returns:

The flushed JsonWriter object.

writeStartObject

public JsonWriter writeStartObject()

Description copied from class: JsonWriter

Writes a JSON start object ({).

Specified by:

writeStartObject in class JsonWriter

Returns:

The updated JsonWriter object.

writeEndObject

public JsonWriter writeEndObject()

Description copied from class: JsonWriter

Writes a JSON end object (}).

If the current writing context isn't an object an IllegalStateException will be thrown.

Specified by:

writeEndObject in class JsonWriter

Returns:

The updated JsonWriter object.

writeStartArray

public JsonWriter writeStartArray()

Description copied from class: JsonWriter

Writes a JSON start array ([).

writeBinary

public JsonWriter writeBinary(byte[] value)

Description copied from class: JsonWriter

Writes a JSON binary value.

A value is always written no matter whether value is null, if null shouldn't be written this API call must be null guarded. Or, use JsonWriter.writeBinary(byte[], boolean) to indicate whether null should be written.

This API is used instead of JsonWriter.writeBinaryField(String, byte[]) when the value needs to be written to the root of the JSON value, as an element in an array, or after a call to JsonWriter.writeFieldName(String).

Specified by:

Parameters:

value - Binary value to write.

Returns:

The updated JsonWriter object.

writeBoolean

The updated JsonWriter object.

writeDouble

public JsonWriter writeDouble(double value)

Description copied from class: JsonWriter

Writes a JSON double value.

This API is used instead of JsonWriter.writeDoubleField(String, double) when the value needs to be written to the root of the JSON value, as an element in an array, or after a call to JsonWriter.writeFieldName(String).
