Dispatcher Description

dispatcher is a Python library extracted from Django's dispatch module.OverviewSignals are useful when two otherwise unrelated pieces of code depend on each other.The general pattern is that a *receiver* (or listener) may *subscribe* (or listen) to the *signal* of a *sender*.When the sender sends (or broadcasts) a signal, the receiver is called.Here is an excerpt from the PyPubSub documentation about the advantages of the signal pattern:* the sender/listener do not need to import each other;* a sender doesn't need to know * "who" gets the messages, * what the listeners will do with the data, * or even *if* any listener will get the message data;* similarly, listeners do not necessarily need to worry about where messages come from.Product's homepage
