                            org.eclipse.emf.ecore.EClass clazz)

Method Detail

pullInto

public void pullInto(java.util.Collection<Tuple> collector)

Description copied from interface: Supplier

pulls the contents of this object in this particular moment into a target collection

Specified by:

pullInto in interface Supplier

disconnect

public void disconnect()

Description copied from interface: Disconnectable

Disconnects this rete engine component from the underlying model. Disconnecting enables the garbage collection mechanisms to dispose of the rete network.

Specified by:

disconnect in interface Disconnectable

constructIndex

public ProjectionIndexer constructIndex(TupleMask mask,
                                        TraceInfo... traces)

Description copied from interface: Supplier

Instantiates (or reuses, depending on implementation) an index according to the given mask. Intended for internal use; clients should invoke through Library instead to enable reusing.

Specified by:

constructIndex in interface Supplier

Overrides:

constructIndex in class StandardNode

getNullIndexer

public NullIndexer getNullIndexer()

Returns:

the nullIndexer

getIdentityIndexer

public IdentityIndexer getIdentityIndexer()

Returns:

the identityIndexer
