Constructor Details

OptimizedSetImpl

public OptimizedSetImpl(CASOperation firstStore)

Construct an optimized get starting with the given get operation.

Method Details

addOperation

public void addOperation(CASOperation op)

size

public int size()

bytes

public int bytes()

initialize

public void initialize()

Description copied from interface: Operation

Initialize this operation. This is used to prepare output byte buffers and stuff.

Specified by:

initialize in interface Operation

Specified by:

initialize in class BaseOperationImpl

finishedPayload

protected void finishedPayload(byte[] pl)
                        throws IOException

Overrides:

finishedPayload in class OperationImpl
