public interface WorkingMemoryEntryPoint
extends org.drools.runtime.rule.WorkingMemoryEntryPoint

An interface for instances that allow handling of entry-point-scoped facts

Method Summary

WorkingMemoryEntryPoint	getWorkingMemoryEntryPoint(String name)
FactHandle	insert(Object object) Assert a fact.
FactHandle	insert(Object object, boolean dynamic) Insert a fact registering JavaBean PropertyChangeListeners on the Object to automatically trigger update calls if dynamic is true.
void	retract(org.drools.runtime.rule.FactHandle handle) Retract a fact.
void	update(org.drools.runtime.rule.FactHandle handle, Object object) Inform the WorkingMemory that a Fact has been modified and that it should now update the network.

Method Detail

insert

FactHandle insert(Object object)
                  throws FactException

Assert a fact.

Specified by:

insert in interface org.drools.runtime.rule.WorkingMemoryEntryPoint

Parameters:

object - The fact object.

Returns:

The new fact-handle associated with the object.

Throws:

FactException - If a RuntimeException error occurs.

insert

FactHandle insert(Object object,
                  boolean dynamic)
                  throws FactException

Insert a fact registering JavaBean PropertyChangeListeners on the Object to automatically trigger update calls if dynamic is true.

Parameters:

object - The fact object.

dynamic - true if Drools should add JavaBean PropertyChangeListeners to the object.

Returns:

The new fact-handle associated with the object.

Throws:

FactException - If a RuntimeException error occurs.

retract

void retract(org.drools.runtime.rule.FactHandle handle)
             throws FactException

Retract a fact.

Specified by:

retract in interface org.drools.runtime.rule.WorkingMemoryEntryPoint

Parameters:

handle - The fact-handle associated with the fact to retract.

Throws:

FactException - If a RuntimeException error occurs.

update

void update(org.drools.runtime.rule.FactHandle handle,
            Object object)
            throws FactException

Inform the WorkingMemory that a Fact has been modified and that it should now update the network.

Specified by:

update in interface org.drools.runtime.rule.WorkingMemoryEntryPoint

Parameters:

handle - The fact-handle associated with the fact to modify.

object - The new value of the fact.

Throws:

FactException - If a RuntimeException error occurs.
