Interface WorkingMemory

All Superinterfaces:

WorkingMemoryEntryPoint

All Known Subinterfaces:

KnowledgeRuntime, StatefulKnowledgeSession

All Known Implementing Classes:

StatefulProcessSession

public interface WorkingMemory
extends WorkingMemoryEntryPoint

The WorkingMemory is a super-interface for all StatefulKnowledgeSessions. Although, users are encouraged to use StatefulKnowledgeSession or KnowledgeRuntime interface instead of WorkingMemory interface, specially because of the dispose() method that is only available in the StatefulKnowledgeSession interface.

Method Detail

halt

void halt()

Request the engine to stop firing rules. If the engine is currently firing a rule, it will finish executing this rule's consequence before stopping.

This method will not remove active activations from the Agenda. In case the application later wants to continue firing rules from the point where it stopped, it should just call org.drools.runtime.StatefulKnowledgeSession.fireAllRules() or org.drools.runtime.StatefulKnowledgeSession.fireUntilHalt() again.

getAgenda

Agenda getAgenda()

Returns a reference to this session's Agenda.

Returns:

getWorkingMemoryEntryPoint

WorkingMemoryEntryPoint getWorkingMemoryEntryPoint(String name)

Returns the WorkingMemoryEntryPoint instance associated with the given name.

Parameters:

Returns:

getWorkingMemoryEntryPoints

Collection<? extends WorkingMemoryEntryPoint> getWorkingMemoryEntryPoints()

Returns a collection of all available working memory entry points for this session.

Returns:

the collection of all available entry points for this session

getQueryResults

QueryResults getQueryResults(String query,
                             Object... arguments)
