getMessage

public String getMessage()

stateAfter

public FrameState stateAfter()

Description copied from interface: StateSplit

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

Specified by:

stateAfter in interface StateSplit

setStateAfter

public void setStateAfter(FrameState x)

Description copied from interface: StateSplit

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

Specified by:

setStateAfter in interface StateSplit

hasSideEffect

public boolean hasSideEffect()

Description copied from interface: StateSplit

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.

Specified by:

hasSideEffect in interface StateSplit
