Class QueryPlanData

java.lang.Object

com.redhat.lightblue.assoc.QueryPlanData

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

IndexedFieldScorerData

public class QueryPlanData
extends Object
implements Serializable

Instances of this class is used to associate additional data to query plan nodes and edges. The actual implementation of QueryPlanData is determined by the caller based on the iterator and scorer used. It is expected that particular iterator and scorers will need different types of data associated with nodes to process the query plan. Subclasses should override the newInstance and copyFrom methods
