Method Summary

Modifier and Type	Method and Description
ValueNode	canonical(CanonicalizerTool tool, ValueNode forValue) Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.
static ValueNode	create(MetaAccessProvider metaAccess, ConstantReflectionProvider constantReflection, ValueNode value, Kind boxingKind)
private static ValueNode	findSynonym(MetaAccessProvider metaAccess, ConstantReflectionProvider constantReflection, ValueNode forValue, Kind boxingKind)
Kind	getBoxingKind()
ValueNode	getValue() Gets the current value of the input, so that calling Canonicalizable.Unary.canonical(CanonicalizerTool, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).
void	lower(LoweringTool tool) Expand this node into lower level nodes expressing the same semantics.
void	virtualize(VirtualizerTool tool) A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized.

Method Detail

getValue

public ValueNode getValue()

Description copied from interface: Canonicalizable.Unary

Gets the current value of the input, so that calling Canonicalizable.Unary.canonical(CanonicalizerTool, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).

Specified by:

getValue in interface Canonicalizable.Unary<ValueNode>

create

public static ValueNode create(MetaAccessProvider metaAccess,
                               ConstantReflectionProvider constantReflection,
                               ValueNode value,
                               Kind boxingKind)

getBoxingKind

public Kind getBoxingKind()

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

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

canonical

public ValueNode canonical(CanonicalizerTool tool,
                           ValueNode forValue)

Description copied from interface: Canonicalizable.Unary

Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.

Specified by:

canonical in interface Canonicalizable.Unary<ValueNode>

findSynonym

private static ValueNode findSynonym(MetaAccessProvider metaAccess,
                                     ConstantReflectionProvider constantReflection,
                                     ValueNode forValue,
                                     Kind boxingKind)
