Class FSTObjectOutputNoShared

java.lang.Object

org.nustaq.serialization.FSTObjectOutput

org.nustaq.serialization.FSTObjectOutputNoShared

All Implemented Interfaces:

DataOutput, ObjectOutput, AutoCloseable

public class FSTObjectOutputNoShared
extends FSTObjectOutput

Subclass optimized for "unshared mode". Cycles and Objects referenced more than once will not be detected. Additionally JDK compatibility is not supported (read/writeObject and stuff). Use case is highperformance serialization of plain cycle free data (e.g. messaging). Can perform significantly faster (20-40%).

Constructor and Description
FSTObjectOutputNoShared() serialize without an underlying stream, the resulting byte array of writing to this FSTObjectOutput can be accessed using getBuffer(), the size using getWritten().
FSTObjectOutputNoShared(FSTConfiguration conf) serialize without an underlying stream, the resulting byte array of writing to this FSTObjectOutput can be accessed using getBuffer(), the size using getWritten().
FSTObjectOutputNoShared(OutputStream out) Creates a new FSTObjectOutput stream to write data to the specified underlying output stream.
FSTObjectOutputNoShared(OutputStream out, FSTConfiguration conf) Creates a new FSTObjectOutputNoShared stream to write data to the specified underlying output stream.

Constructor Detail

FSTObjectOutputNoShared

public FSTObjectOutputNoShared(OutputStream out)

Creates a new FSTObjectOutput stream to write data to the specified underlying output stream. uses Default Configuration singleton

Parameters:

out -

FSTObjectOutputNoShared

public FSTObjectOutputNoShared(OutputStream out,
                               FSTConfiguration conf)

Creates a new FSTObjectOutputNoShared stream to write data to the specified underlying output stream. The counter written is set to zero. Don't create a FSTConfiguration with each stream, just create one global static configuration and reuse it. FSTConfiguration is threadsafe.

Parameters:

out - the underlying output stream, to be saved for later use.

conf -

FSTObjectOutputNoShared

public FSTObjectOutputNoShared(FSTConfiguration conf)

serialize without an underlying stream, the resulting byte array of writing to this FSTObjectOutput can be accessed using getBuffer(), the size using getWritten().

Don't create a FSTConfiguration with each stream, just create one global static configuration and reuseit. FSTConfiguration is threadsafe.

Parameters:

conf -

FSTObjectOutputNoShared

public FSTObjectOutputNoShared()

serialize without an underlying stream, the resulting byte array of writing to this FSTObjectOutput can be accessed using getBuffer(), the size using getWritten().

uses default configuration singleton

writeObjectWithContext

protected FSTClazzInfo writeObjectWithContext(FSTClazzInfo.FSTFieldInfo referencee,
                                              Object toWrite)
                                       throws IOException

Overrides:

writeObjectWithContext in class FSTObjectOutput

Throws:

IOException

public void resetForReUse(byte[] out)

Overrides:

resetForReUse in class FSTObjectOutput
