BusinessProcessInvoke(Action) Method

Invokes a action that will be handled by an Handler.

Definition

Namespace: Firefly.Box
Assembly: Firefly.Box (in Firefly.Box.dll) Version: debug-master-v:33791
C#
public void Invoke(
	Action action
)

Parameters

action  Action
The Action to be invoked

Remarks

When the Handler method is called, the framework will iterate the Handlers property collection until it will find an Handler that matches the action.
If no matching Handler was found, or if the Handled property was set to true, the framework will iterate the calling task's Handlers property collection and so on.
The deference between Raise and Invoke, is that Raise will queue the action, and process it the next time the framework is idle, while Invoke will process it immediately
When invoking a {0} (for example {1}) or a Key Combination, only the relevant Handlers will execute, but the command it self will not. In order to run the command itself use .
