Examples of ObjectTypeNode

org.drools.core.reteoo.ObjectTypeNode
ObjectTypeNodes are responsible for filtering and propagating the matching fact assertions propagated from the Rete node using ObjectType interface. The assert and retract methods do not attempt to filter as this is the role of the Rete node which builds up a cache of matching ObjectTypdeNodess for each asserted object, using the matches(Object object) method. Incorrect propagation in these methods is not checked and will result in ClassCastExpcections later on in the network. Filters Objects coming from the Rete using a ObjectType semantic module. @see Rete



org.drools.reteoo.ObjectTypeNode

Filters Objects coming from the Rete using a ObjectType semantic module.  It receives Objects from the Rete, uses a ObjectType instance to determine membership, and propagates matching Objects further to all matching ParameterNodes.
