E&S CVS Commit: PyProtocols - Added 'when()' methods to generic functions, so that it's easier to add

[pje at eby-sarna.com]

Module Name:	PyProtocols
Committed By:	pje
Date:		Sun Nov  7 06:49:55 UTC 2004

Modified Files:
	PyProtocols/src/dispatch: functions.py interfaces.py
	PyProtocols/src/protocols/tests: test_dispatch.py

Log Message:
Added 'when()' methods to generic functions, so that it's easier to add
cases to generic functions in other modules, e.g.::

    @config.getStreamFactory.when([str,unicode])
    def open_url(source, context):
        # etc.

Also, if you are only using 'SimpleGeneric' functions, you can avoid
loading the parser and predicate modules if you only use 'when()' methods
instead of calling 'dispatch.when()'.
