BufferManagerReadGrow

public BufferManagerReadGrow()

Method Details

processFragment

public void processFragment(ByteBuffer byteBuffer,
 FragmentMessage header)

Description copied from interface: BufferManagerRead

Case: Called from ReaderThread on complete message or fragments. The given buffer 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

Parameters:

byteBuffer - buffer to read from

header - header of fragment

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

Parameters:

msg - message header

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

Parameters:

byteBuffer - Current buffer, to return to pool

Returns:

Buffer containing new data

See Also:

• BufferManagerRead.isFragmentOnUnderflow()

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

Returns:

if fragments will be read.

See Also:

• BufferManagerRead.underflow(ByteBuffer)

cancelProcessing

public void cancelProcessing(int requestId)

Description copied from interface: BufferManagerRead

Signals that the processing be cancelled.

Specified by:

cancelProcessing in interface BufferManagerRead

Parameters:

requestId - ID of the request to cancel

getMarkAndResetHandler

public MarkAndResetHandler getMarkAndResetHandler()

Description copied from interface: BufferManagerRead

Returns the mark/reset handler for this stream.

Specified by:

getMarkAndResetHandler in interface BufferManagerRead

Returns:

The mark/reset handler for this stream.

mark

public void mark(RestorableInputStream is)

Specified by:

mark in interface MarkAndResetHandler

fragmentationOccured

public void fragmentationOccured(ByteBuffer byteBuffer)

Specified by:

fragmentationOccured in interface MarkAndResetHandler

reset

public void reset()

Specified by:

reset in interface MarkAndResetHandler

close

public void close(ByteBuffer byteBuffer)

Description copied from interface: BufferManagerRead

Close BufferManagerRead and perform any outstanding cleanup.

Specified by:

close in interface BufferManagerRead

Parameters:

byteBuffer - buffer to return to the pool
