Implementation of IBB at the target side
You may read the block-size after accept
# File lib/xmpp4r/bytestreams/helper/ibb/target.rb, line 13 def initialize(stream, session_id, initiator_jid, target_jid) # Target and Initiator are swapped here, because we're the target super(stream, session_id, target_jid, initiator_jid) @accept_ready = Semaphore::new end
Wait for the initiator side to start the stream.
