Syntax

public class PlanNode : PlanPseudoNode

The PlanNode type exposes the following members.

Constructors

	Name	Description
	PlanNode(String)	Instantiates a root plan node.
	PlanNode(PatternNode, Int32, Boolean)	Instantiates a node plan node.
	PlanNode(PatternEdge, Int32, Boolean, PlanNode, PlanNode)	Instantiates an edge plan node.

Properties

	Name	Description
	Incoming	Returns all incoming plan edges. (Overrides PlanPseudoNodeIncoming.)
	TopNode	outermost enclosing supernode, the node itself if not contained within a supernode (Inherited from PlanPseudoNode.)
	TopSuperNode	outermost enclosing supernode, null if not contained within a supernode (Inherited from PlanPseudoNode.)

Methods

	Name	Description
	GetCheapestIncoming	Returns the cheapest incoming plan edge and its cost, excluding nodes contained within the given top super node (if given) (Overrides PlanPseudoNodeGetCheapestIncoming(PlanPseudoNode, Single).)
	PreferNewEdge	Decides whether a new edge is better than a known best edge up to now. (Inherited from PlanPseudoNode.)
	ToString	(Overrides ObjectToString.)

	NodeType
	PatternEdgeSource	Only valid if this plan node is representing a pattern edge, then PatternEdgeSource gives us the plan node made out of the source node of the edge
	PatternEdgeTarget	Only valid if this plan node is representing a pattern edge, then PatternEdgeTarget gives us the plan node made out of the target node of the edge
