  Initiate a low-copy transfer between two stream channels. The pool should be a direct buffer pool for best performance.

  Parameters:

  source - the source channel

  sink - the target channel

  sourceListener - the source listener to set and call when the transfer is complete, or null to clear the listener at that time

  sinkListener - the target listener to set and call when the transfer is complete, or null to clear the listener at that time

  readExceptionHandler - the read exception handler to call if an error occurs during a read operation

  writeExceptionHandler - the write exception handler to call if an error occurs during a write operation

  pool - the pool from which the transfer buffer should be allocated
