[Springframework-rcp-dev] Spring-RCP enhancement: ReflectionbasedVisualAction

[Achleitner T. <ac...@ec...>]

Hi Keith!

I had a closer look at ActionHandler and DefaultVisualAction.=20
I compared it with our existing implementation, where we have a concrete
Action class based on a pair of method names (action and guard) that
will be executed on the action handler via reflection api.

What i did now was that i ported our code to a new class
org.springframework.rcp.action.ReflectionbasedVisualAction extending
DefaultVisualAction.

Class ReflectionbasedVisualAction provides a "call by name" mechanism
for invoking methods and automatic checking of the isEnabled state by
means of calling the guard actionMethod. Checking the isEnabled state of
an action is performed automatically in the background (triggered by
input events).

To get it working i had to create a public getter in
DefaultVisualAction: getActionHandler.

I attached the source file. Maybe you can make any use of it. For more
details see the class comment.=20
