Class PlannerGraph<N extends PlannerGraph.AbstractNode,E extends PlannerGraph.AbstractEdge>

java.lang.Object

com.apple.foundationdb.record.query.plan.temp.PlannerGraph<N,E>

Type Parameters:

N - node type

E - edge type

public class PlannerGraph<N extends PlannerGraph.AbstractNode,E extends PlannerGraph.AbstractEdge>
extends Object

The planner graph class. Objects of this class are computed by InternalPlannerGraphProperty, i.e., they get computed by walking a PlannerExpression DAG. Once computed, the property is immutable.
