StoreFieldNode

public StoreFieldNode(ValueNode object,

                      ValueNode value)

                      ValueNode value,
                      FrameState stateAfter)

Method Detail

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

value

public ValueNode value()

virtualize

public void virtualize(VirtualizerTool tool)

Description copied from interface: Virtualizable

A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized. All modifications must be made through the supplied tool, and not directly on the node, because by the time this method is called the virtualized/non-virtualized state is still speculative and might not hold because of loops, etc.

Specified by:

virtualize in interface Virtualizable

Parameters:

tool - the tool used to describe the effects of this node

getState

public FrameState getState()
