All Implemented Interfaces:

IterableNodeType, NodeInterface, Simplifiable, AnchoringNode, GuardingNode, LIRLowerable, NodeWithState, StateSplit, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

AbstractMergeNode, DispatchBeginNode, EntryMarkerNode, LoopExitNode, StartNode

public abstract class BeginStateSplitNode
extends AbstractBeginNode
implements StateSplit

Base class for AbstractBeginNodes that are associated with a frame state. TODO (dnsimon) this not needed until AbstractBeginNode no longer implements StateSplit which is not possible until loop peeling works without requiring begin nodes to have frames states.
