Member Function Documentation
◆ apply()
|
virtual |
Make a single attempt to apply this Action.
This is the main entry point for applying changes to a function that are specific to this Action. The method can inspect whatever it wants to decide if the Action does or does not apply. Changes are indicated by incrementing the count field.
- Parameters
-
data is the function to inspect/modify
- Returns
- 0 for a complete application, -1 for a partial completion (due to breakpoint)
Implements Action.

◆ clone()
|
inlinevirtual |
Clone the Action.
If this Action is a member of one of the groups in the grouplist, this returns a clone of the Action, otherwise NULL is returned.
- Parameters
-
grouplist is the list of groups being cloned
- Returns
- the cloned Action or NULL
