Examples of org.drools.rule.EntryPoint

org.drools.rule.EntryPoint
This class defines a Rete "Entry Point". An entry point is used as a source of facts that are scoped to a separate alpha network. The alpha network is not shared among separate entry points and this allows them to safelly run in parallel and concurrent modes.
