require 'em/streamer'

# Streams an IO object over a given connection. Streaming begins once the object is
# instantiated. Typically IOStreamer instances are not reused.  IOStreamer includes
# a 16K buffer.  If streaming from a file, FileStreamer is more efficient.
#
# @example
#
#  module FileSender
#    def post_init
# @example
#
#  module SocketSender
#      socket = TCPSocket.new('localhost', 2000)
#      streamer = EventMachine::IOStreamer.new(self, socket)
#      streamer.callback{
#        # all data was sent successfully
#        close_connection_after_writing
#      }
#    end
#  end

# Stream from any IO object, similar to FileStreamer
