Class: Ap4r::Carriers

Inherits:
Object show all
Defined in:
lib/ap4r/carrier.rb

Overview

This class aims to balance loads of several reliable-msg servers. Only P2P channells (queues) are considered so far. Now reliable-msg can not be accessed from remote (means “not localhost”). Alpha status now. – TODO: refactoring with dispatcher.rb, around thread group, etc. 2007/05/09 by shino
