Hi,
I recently needed to add introspection support so a user could use one of the
C++ auto glue generation frameworks. I found an OLD set of patches for this,
but they were very out of date. Instead of using these, I kept the same
usage pattern but made a new implementation based on the current 1.2 code
base.
I've implemented this support by making the following changes:
* Create IntrospectiveHandlerMapping - a subclass of HandlerMapping that
allows iteration over the list of handlers.
* Create a new subclass of SystemHandler called IntrospectiveHandler. This
class implements the system.listMethods, system.methodHelp and
system.methodSignature calls. I decided to make a subclass, because I
thought some may not want introspection.
The listMethods/methodHelp functions use the same 'marker' system the old
patches did. i.e. to mark a method as public via XMLRPC, you must declare a
static of the form:
static [final] public boolean <methodName>_public = true;
This is necessary to avoid exposing a zillion of public methods which are not
intended for XMLRPC.
If you wish to provide 'help text' via introspection, you can optionally
define a static string of the form:
static [final] public String <methodName>_help = "This method will make you
rich";
* I've also changed the sample server to use this IntrospectiveHandler
instead of the old SystemHandler.
* I've created a Servlet to automate the dispatching to handlers
Do ya'll want any of these changes? Who should I send the diffs to?
Ispiri is happy to contribute these changes under the Apache license.
