Examples of org.drools.reteoo.EntryPointNode

org.drools.reteoo.EntryPointNode
A node that is an entry point into the Rete network. As we move the design to support network partitions and concurrent processing of parts of the network, we also need to support multiple, independent entry points and this class represents that. It replaces the function of the Rete Node class in previous designs. @see ObjectTypeNode @author Edson Tirelli
