Method Detail

getEntryPointId

public String getEntryPointId()

Description copied from interface: WorkingMemoryEntryPoint

Returns the String Id of this entry point

Specified by:

getEntryPointId in interface WorkingMemoryEntryPoint

Returns:

insert

public FactHandle insert(Object object)

Description copied from interface: WorkingMemoryEntryPoint

Inserts a new fact into this entry point

Specified by:

insert in interface WorkingMemoryEntryPoint

Parameters:

object - the fact to be inserted

Returns:

the fact handle created for the given fact

retract

public void retract(FactHandle handle)

Description copied from interface: WorkingMemoryEntryPoint

Retracts the fact for which the given FactHandle was assigned.

Specified by:

retract in interface WorkingMemoryEntryPoint

Parameters:

handle - the handle whose fact is to be retracted.

update

public void update(FactHandle handle,
          Object object)

Description copied from interface: WorkingMemoryEntryPoint

Updates the fact for which the given FactHandle was assigned with the new fact set as the second parameter in this method.

Specified by:

update in interface WorkingMemoryEntryPoint

Parameters:

handle - the FactHandle for the fact to be updated.

object - the new value for the fact being updated.

getFactHandle

public FactHandle getFactHandle(Object object)

Description copied from interface: WorkingMemoryEntryPoint

Returns the fact handle associated with the given object. It is important to note that this method behaves in accordance with the configured assert behaviour for this knowledge base (either IDENTITY or EQUALITY).

Specified by:

getFactHandle in interface WorkingMemoryEntryPoint

Parameters:

object - the fact for which the fact handle will be returned.

Returns:

the fact handle for the given object, or null in case no fact handle was found for the given object.

getObject

public Object getObject(FactHandle factHandle)

Description copied from interface: WorkingMemoryEntryPoint

Returns the object associated with the given FactHandle.

Specified by:

getObject in interface WorkingMemoryEntryPoint

Returns:

getObjects

public Collection<Object> getObjects()

Description copied from interface: WorkingMemoryEntryPoint

Returns all facts from the current session as a Collection.

This class is not a general-purpose Collection implementation! While this class implements the Collection interface, it intentionally violates Collection general contract, which mandates the use of the equals method when comparing objects.

Instead the approach used when comparing objects with the contains(Object) method is dependent on the WorkingMemory configuration, where it can be configured for Identity or for Equality.

Specified by:

getObjects in interface WorkingMemoryEntryPoint

Returns:

getObjects

public Collection<Object> getObjects(ObjectFilter filter)

Description copied from interface: WorkingMemoryEntryPoint

Returns all facts from the current session that are accepted by the given ObjectFilter.

Specified by:

getObjects in interface WorkingMemoryEntryPoint

Parameters:

filter - the filter to be applied to the returned collection of facts.

Returns:

getFactHandles

public <T extends FactHandle> Collection<T> getFactHandles()

Description copied from interface: WorkingMemoryEntryPoint

Returns all FactHandles from the current session.

Specified by:

getFactHandles in interface WorkingMemoryEntryPoint

Returns:

getFactHandles

public <T extends FactHandle> Collection<T> getFactHandles(ObjectFilter filter)

Description copied from interface: WorkingMemoryEntryPoint

Returns all FactHandles from the current session for which the facts are accepted by the given filter.

Specified by:

getFactHandles in interface WorkingMemoryEntryPoint

Parameters:

filter - the filter to be applied to the returned collection of FactHandles.

Returns:

getFactCount

public long getFactCount()

Description copied from interface: WorkingMemoryEntryPoint

Returns the total number of facts currently in this entry point

Specified by:

getFactCount in interface WorkingMemoryEntryPoint

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
