Subject svn commit: r711365 - in /incubator/qpid/trunk/qpid/cpp: rubygen/ rubygen/framing.0-10/ src/qpid/broker/ src/qpid/cluster/ src/qpid/framing/ src/tests/
Date Tue, 04 Nov 2008 19:52:50 GMT
Author: aconway
Date: Tue Nov  4 11:52:49 2008
New Revision: 711365

URL: http://svn.apache.org/viewvc?rev=711365&view=rev
Log:

constants.rb: generate type code constants for AMQP types. Useful with Array.

framing/Array:
 - added some std:::vector like functions & typedefs.
 - use TypeCode enums, human readable  ostream << operator.
