public class DiscriminatorBucketNode
extends SingleInputNode

A bucket holds a filtered set of tuples of its parent DiscriminatorDispatcherNode. Exactly those that have the given bucket key at their discrimination column.

During operation, tuple contents and bucket keys have already been wrapped using IQueryRuntimeContext.wrapElement(Object)

Since:

DiscriminatorBucketNode

public DiscriminatorBucketNode(ReteContainer reteContainer,
 Object bucketKey)

Parameters:

bucketKey - will be wrapped using IQueryRuntimeContext.wrapElement(Object)

Method Details

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)

update

public void update(Direction direction,
 Tuple updateElement,
 Timestamp timestamp)

Description copied from interface: Receiver

Updates the receiver with a newly found or lost partial matching.

getBucketKey

public Object getBucketKey()

appendParent

public void appendParent(Supplier supplier)

Description copied from interface: Receiver

appends a parent that will continuously send insert and revoke updates to this supplier

Specified by:

appendParent in interface Receiver

Overrides:

appendParent in class SingleInputNode

getDispatcher

public DiscriminatorDispatcherNode getDispatcher()

toStringCore

protected String toStringCore()

Description copied from class: BaseNode

clients should override this to append before the tag / trace indicators

Overrides:

toStringCore in class BaseNode
