Member Function Documentation

◆ apply()

int4 ActionDynamicSymbols::apply ( Funcdata data)

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.

datais the function to inspect/modify
0 for a complete application, -1 for a partial completion (due to breakpoint)

Implements Action.

◆ clone()

virtual Action* ActionDynamicSymbols::clone ( const ActionGroupList grouplist) const

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.

grouplistis the list of groups being cloned
the cloned Action or NULL
