Method Details

networkStructureChanged

public void networkStructureChanged()

Description copied from interface: NetworkStructureChangeSensitiveNode

At the time of the invocation, the dependency graph has already been updated.

Specified by:

networkStructureChanged in interface NetworkStructureChangeSensitiveNode

Overrides:

networkStructureChanged in class StandardNode

initializeWith

public void initializeWith(ProjectionIndexer projectionIndexer)

update

protected void update(Direction direction,
 Tuple updateElement,
 Tuple signature,
 boolean change,
 Timestamp timestamp)

getDefaultTuple

protected Tuple getDefaultTuple(ITuple key)

pullInto

public void pullInto(Collection<Tuple> collector,
 boolean flush)

Description copied from interface: Supplier

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

Parameters:

flush - if true, flushing of messages is allowed during the pull, otherwise flushing is not allowed

pullIntoWithTimeline

public void pullIntoWithTimeline(Map<Tuple,Timeline<Timestamp>> collector,
 boolean flush)

getPulledContents

public Set<Tuple> getPulledContents(boolean flush)

Description copied from interface: Supplier

Returns the contents of this object in this particular moment. For memoryless nodes, this may involve a costly recomputation of contents. The result is returned as a Set, even when it has multiplicities (at the output of TrimmerNode).

Intended mainly for debug purposes; therefore flushing is performed only if explicitly requested During runtime, flushing may be preferred; see

invalid reference

ReteContainer#pullContents(Supplier)

Specified by:

getPulledContents in interface Supplier

Overrides:

getPulledContents in class StandardNode

getOuterIndexer

public Indexer getOuterIndexer()
