All Implemented Interfaces:

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 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
