Constructor Detail

BufferedSelectionChannel

public BufferedSelectionChannel(Buffer buffer,
                                T source,
                                WakeupListener wakeupListener)

Deprecated.

Constructor.

Parameters:

buffer - The source byte buffer, typically remaining from previous read processing.

source - The source channel.

wakeupListener - The wakeup listener that will be notified.

Method Detail

canLoop

public boolean canLoop(Buffer buffer,
                       java.lang.Object... args)

Deprecated.

Indicates if the processing loop can continue.

Specified by:

canLoop in interface BufferProcessor

Parameters:

buffer - The IO buffer to drain.

args - The optional arguments to pass back to the callbacks.

Returns:

True if the processing loop can continue.

close

public void close()
           throws java.io.IOException

Deprecated.

Description copied from class: WrapperChannel

Delegates to the wrapped channel.

Specified by:

getBuffer

public Buffer getBuffer()

Deprecated.

Returns the source buffer.

Returns:
