Where can I find a list of all my event handlers?

[Joel Tobey]

I'm doing some fancy SES URL magic and I'm trying to determine what event name I want to use. It's fun because '/foo' is a different event than '/foo/bar'. (Where one might think the later is still the '/foo' event with the variable 'bar')

My first thought to do this is to run some logic against the full list of event handler names, but I'm having trouble finding where to do that. The _mg.hasEventHandler() method seems to be the one, but it only checks for loaded event handler objects. Since MG lazy inits, not all of the event handlers load during the init.

Can someone help me with accessing the list of event handlers from my XML file? Or if you have another solution to what I'm trying to do?

Thanks!

The XMLModuleLoader.cfc is probably where you want to look.

If you want a list of event handlers, you can look at the method, listEventHandlers. This is designed to deal only with a single XML config, but you can simply expand the logic to read in all of your files and list them. 

The method, hasEventHandlerDefinition, will look through all of the MG config files and try to find instances of a specific event name. You may be able to copy this logic to print out all of the Event Handler names.

This CFC is not available in the public Model Glue namespace. You can get access to the loaded XML files though by injecting the bean modelglue.ModelGlue into your own CFC and calling: getModuleLoaderArray().

As Dan indicated, there are ways to get at the entire set of event
handlers, but this isn't exposed directly. Do you actually need a
list/array of all the event names, or would checking to see if a
particular event name exists be sufficient?

If the latter is the case, then the hasEventHandler() method *should*
work, as it turns around and calls hasEventHandlerDefinition() on the
module loader array, and therefore it shouldn't matter whether the
event handler in question has been loaded yet.

Ah, I think I figured it out. I was trying to do this logic in my
SesUrlManager and that seems to be too early in the life cycle. When I
was in a Controller, the hasEventHandler() method works as expected.
For my situation, I believe the best way to go is to hit the same
"event" for all requests, do my event resolving logic in the
Controller and then execute the "real" event.

Thanks for your help and input.

Joel,

It should be possible to do what you want by inserting your own phase into the request lifecycle. I do this in my apps to provide url routing.

eg. /user/{username}

The code is on github - https://github.com/d1rtym0nk3y/ModelGlue-Url-Router

The trick is to override url.event before the MG gets to the invocation phase, so you can do this during population.

I'm on my mobile atm and there no docs apart from the example but if you have any questions I'll take a look when I'm back in the office and try to help
