Description

One of the major optimizations for generating events in oak-jcr is to avoid traversal into sub trees when there are path filters on an observation listener. Another optimization could be done based on the node type filters provided by a listener. If oak-jcr knows the affected node types of a cache set it could shortcut event processing in case the listeners node type filter is disjoint.
