Overview

Manages the association between an Event and the method which should process on the context object associated with an occurance of the event.

Each type is identified by a unique #type value.

Examples:


# SCENARIO: A part of an application handles extracting and decrypting
#            data received from a remote endpoint.
#
#            An EventType is created to notify handlers that such a
#            situation has occurred.

ENCRYPTED_RECV = 10000 # the unique constant value for the event

# create a new event type which, when it occurs, invokes a method
# named :on_encrypted_data when a handler is notified of its occurrance
Qpid::Proton::Event::ENCRYPTED_RECV =
  Qpid::Proton::Event::EventType.new(ENCRYPTED_RECV, :on_encrypted_data)
