Method Detail

getActiveNode

public Node 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
