Constructor Details

TransitiveClosureNodeIndexer

public TransitiveClosureNodeIndexer(TupleMask mask,
 IncSCCAlg<Object> tcAlg,
 TransitiveClosureNode tcNode)

Method Details

get

public Collection<Tuple> get(Tuple signature)

Specified by:

get in interface Indexer

Returns:

all stored tuples that conform to the specified signature, null if there are none such. CONTRACT: do not modify!

getBucketCount

public int getBucketCount()

Specified by:

getBucketCount in interface IterableIndexer

Returns:

the number of signatures whose tuple group is not empty

getSignatures

public Collection<Tuple> getSignatures()

Description copied from interface: IterableIndexer

A view consisting of exactly those signatures whose tuple group is not empty

Specified by:

getSignatures in interface IterableIndexer

iterator

public Iterator<Tuple> iterator()

Specified by:

iterator in interface Iterable<Tuple>

propagate

public void propagate(Direction direction,
 Tuple updateElement,
 boolean change)

Since:

2.4

getActiveNode

public Receiver getActiveNode()

Description copied from interface: Indexer

This indexer will be updated whenever a Rete update is sent to the active node (or an equivalent time slot allotted to it). The active node is typically the indexer itself, but it can be a different node such as its parent.

Specified by:

getActiveNode in interface Indexer

Returns:

the active node that operates this indexer
