Method Detail

cancelProcessing

public void cancelProcessing(int requestId)

Specified by:

cancelProcessing in interface BufferManagerRead

processFragment

public void processFragment(ByteBuffer byteBuffer,
                            FragmentMessage msg)

Description copied from interface: BufferManagerRead

Case: Called from ReaderThread on complete message or fragments. The given buf may be entire message or a fragment. The ReaderThread finds the ReadBufferManager instance either in in a fragment map (when collecting - GIOP 1.2 phase 1) or in an active server requests map (when streaming - GIOP 1.2 phase 2). As a model for implementation see IIOPInputStream's constructor of the same name. There are going to be some variations.

Specified by:

processFragment in interface BufferManagerRead

underflow

public ByteBuffer underflow(ByteBuffer byteBuffer)

Description copied from interface: BufferManagerRead

Invoked when we run out of data to read. Obtains more data from the stream.

Specified by:

underflow in interface BufferManagerRead

isFragmentOnUnderflow

public boolean isFragmentOnUnderflow()

Description copied from interface: BufferManagerRead

Returns true if this buffer manager reads fragments when it underflows.

Specified by:

isFragmentOnUnderflow in interface BufferManagerRead

init

public void init(Message msg)

Description copied from interface: BufferManagerRead

Called once after creating this buffer manager and before it begins processing.

Specified by:

init in interface BufferManagerRead

close

public void close(ByteBuffer byteBuffer)

Specified by:

close in interface BufferManagerRead

getByteBufferPool

protected ByteBufferPool getByteBufferPool()

mark

public void mark(com.sun.corba.ee.impl.encoding.RestorableInputStream inputStream)

fragmentationOccured

public void fragmentationOccured(ByteBuffer newFrament)

reset

public void reset()

getMarkAndResetHandler

public com.sun.corba.ee.impl.encoding.MarkAndResetHandler getMarkAndResetHandler()

Description copied from interface: BufferManagerRead

Returns the mark/reset handler for this stream.

Specified by:

getMarkAndResetHandler in interface BufferManagerRead
