Class FSTObjectInputNoShared

java.lang.Object

org.nustaq.serialization.FSTObjectInput

org.nustaq.serialization.FSTObjectInputNoShared

All Implemented Interfaces:

DataInput, ObjectInput, AutoCloseable

public class FSTObjectInputNoShared
extends FSTObjectInput

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%).

public FSTObjectInputNoShared(FSTConfiguration conf)

FSTObjectInputNoShared

public FSTObjectInputNoShared(InputStream in)
                       throws IOException

Creates a FSTObjectInput that uses the specified underlying InputStream.

Parameters:

in - the specified input stream

Throws:

IOException

FSTObjectInputNoShared

public FSTObjectInputNoShared(InputStream in,
 FSTConfiguration conf)

Creates a FSTObjectInput that uses the specified underlying InputStream.

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

Parameters:

in - the specified input stream

conf -
