bufferAvailable

public void bufferAvailable(Buffer buffer)
                     throws Exception

Notifies the IO thread that a Buffer has become available again.

This method will be called from outside the Netty IO thread. The caller will be the buffer pool from which the available buffer comes (i.e. the InputGate).

We have to make sure that the available buffer is handed over to the IO thread in a safe manner.

Specified by:

bufferAvailable in interface BufferAvailabilityListener

Throws:

Exception
