A handler is the pluggable piece of a command that handles execution. Each command can have zero or more handlers associated with it (in general), of which only one will be active at any given moment in time. When the command is asked to execute, it will simply pass that request on to its active handler, if any.

pure virtual |
Registers an instance of IHandlerListener
to listen for changes to properties of this instance.
handlerListener | the instance to register. Must not be null . If an attempt is made to register an instance which is already registered with this instance, no operation is performed. |
|
pure virtual |
Disposes of this handler. This method is run once when the object is no longer referenced. This can be used as an opportunity to unhook listeners from other objects.
Implemented in berry::AbstractHandler.
|
pure virtual |
Executes with the map of parameter values by name.
event | An event containing all the information about the current state of the application; must not be null . |
null
. ExecutionException | if an exception occurred during execution. |
|
pure virtual |
Returns whether this handler is capable of executing at this moment in time. If the enabled state is other than true clients should also consider implementing IHandler2 so they can be notified about framework execution contexts.
true
if the command is enabled; false
otherwise. Implemented in berry::AbstractHandler.
|
pure virtual |
Returns whether this handler is really capable of handling delegation. In the case of a handler that is a composition of other handlers, this reply is intended to indicate whether the handler is truly capable of receiving delegated responsibilities at this time.
true
if the handler is handled; false
otherwise. Implemented in berry::AbstractHandler.
|
pure virtual |
Unregisters an instance of IHandlerListener
listening for changes to properties of this instance.
handlerListener | the instance to unregister. Must not be null . If an attempt is made to unregister an instance which is not already registered with this instance, no operation is performed. |
Implemented in berry::AbstractHandler.
|
pure virtual |
Called by the framework to allow the handler to update its enabled state.
evaluationContext | the state to evaluate against. May be null which indicates that the handler can query whatever model that is necessary. This context must not be cached. |
Implemented in berry::AbstractHandler.
