Detailed Description

A plug's partial invalidation descriptor.

When a plug is touched (invalidated) with no PartialInvalidation provided, it is completly invalidated. In order to optimize some processes, one can precise when the plug is modified that the plug is partially invalidated using objects of a class derived from PartialInvalidation.

For instance, such descriptors can be used to invalidate only a precise path in a Scene value but not all the Scene's content.

virtual Ptr<const PartialInvalidation> maquina::PartialInvalidation::make_union ( const Ptr< const PartialInvalidation > &  self, const Ptr< const PartialInvalidation > &  o  ) const

Parameters

self	The Ptr of this. Ptr.get() == this.
