All Implemented Interfaces:

IMOptimizer

public class MDeduplicationOptimizer
extends AbstractRecursiveOptimizer

Optimizer which will check for presence of strictly identical instances of addons, in terms of behavior.
If found, only one of the multiple instance will be kept, the other ones will be replaced. The goal is to reduce memory impact. In this case, debug information will be merged.
Exception: Addons with name will be not be deduplicated, as they might be used in flow control.
This optimizer has no parameter.

1.5.0
