Method Detail

close

public void close()
           throws java.io.IOException

Closes the writer and the underlying stream.

Specified by:

close in interface IpcStreamWriter

Throws:

java.io.IOException - any error

closeWithoutStream

public void closeWithoutStream()
                        throws java.io.IOException

Closes the writer but NOT the underlying stream.

Specified by:

closeWithoutStream in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeObjectEnd

public void writeObjectEnd()
                    throws java.io.IOException

JSON serialization does not support DOCUMENT_END tokens, so this does nothing. Writes marker signaling end of an object (resp. a document). Will be ignored if underlying implementation doesn't support this kind of marker.

Specified by:

writeObjectEnd in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeObjectStart

public void writeObjectStart()
                      throws java.io.IOException

JSON serialization does not support DOCUMENT_START tokens, so this does nothing. Writes marker signaling start of an object (resp. a document). Will be ignored if underlying implementation doesn't support this kind of marker.

Specified by:

writeObjectStart in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeMappingEnd

public void writeMappingEnd()
                     throws java.io.IOException

Writes marker signaling end of a mapping.

Specified by:

writeMappingEnd in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeMappingStart

public void writeMappingStart()
                       throws java.io.IOException

Writes marker signaling start of a mapping.

Specified by:

writeMappingStart in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeScalarBoolean

public void writeScalarBoolean(boolean b)
                        throws java.io.IOException

Writes boolean value. any error

Specified by:

writeScalarBoolean in interface IpcStreamWriter

Parameters:

b - value to write

Throws:

java.io.IOException - any error

writeScalarDouble

public void writeScalarDouble(double d)
                       throws java.io.IOException

Writes double value.

Specified by:

writeScalarDouble in interface IpcStreamWriter

Parameters:

d - value to write

Throws:

java.io.IOException - any error

writeScalarInt

public void writeScalarInt(int i)
                    throws java.io.IOException

Writes integer value.

Specified by:

writeScalarInt in interface IpcStreamWriter

Parameters:

i - value to write

writeScalarLong

public void writeScalarLong(long i)
                     throws java.io.IOException

Writes long value.

Specified by:

writeScalarLong in interface IpcStreamWriter

Parameters:

i - value to write

Throws:

java.io.IOException - any error

writeScalarString

public void writeScalarString(java.lang.String s)
                       throws java.io.IOException

Writes string value.

Specified by:

writeScalarString in interface IpcStreamWriter

Parameters:

s - value to write

Throws:

java.io.IOException - any error

writeSequenceEnd

public void writeSequenceEnd()
                      throws java.io.IOException

Writes marker signaling end of a sequence.

Specified by:

writeSequenceEnd in interface IpcStreamWriter

java.io.IOException - any error

writeSequenceStart

public void writeSequenceStart()
                        throws java.io.IOException

Writes marker signaling start of a sequence.

Specified by:

writeSequenceStart in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeMappingKey

public void writeMappingKey(java.lang.String s)
                     throws java.io.IOException
