=begin
The only change required for a transport to support BinaryProtocolAccelerated is to implement 2 methods:
  * borrow(size), which takes an optional argument and returns atleast _size_ bytes from the transport, 
                  or the default buffer size if no argument is given
  * consume!(size), which removes size bytes from the front of the buffer

See MemoryBuffer and BufferedTransport for examples.
=end

module Thrift
  class BinaryProtocolAcceleratedFactory < BaseProtocolFactory
    def get_protocol(trans)
      if (defined? BinaryProtocolAccelerated)
        BinaryProtocolAccelerated.new(trans)
      else
        BinaryProtocol.new(trans)
      end
    end
  end
end
