public interface StateSplit
extends NodeWithState

A state split is a node that may have a frame state associated with it.

Method Summary

Modifier and Type	Method and Description
boolean	hasSideEffect() Determines if this node has a side-effect.
void	setStateAfter(FrameState x) Sets the FrameState corresponding to the state of the JVM after execution of this node.
FrameState	stateAfter() Gets the FrameState corresponding to the state of the JVM after execution of this node.

Method Detail

stateAfter

FrameState stateAfter()

Gets the FrameState corresponding to the state of the JVM after execution of this node.

setStateAfter

void setStateAfter(FrameState x)

Sets the FrameState corresponding to the state of the JVM after execution of this node.

hasSideEffect

boolean hasSideEffect()

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.
