Method Summary

Modifier and Type	Method and Description
ValueNode	canonical(CanonicalizerTool tool, ValueNode forJavaClass, ValueNode forObject) 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.
private ValueNode	getJavaClass()
private ValueNode	getObject()
ValueNode	getX() Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).
ValueNode	getY() Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).

Method Detail

getJavaClass

private ValueNode getJavaClass()

getObject

private ValueNode getObject()

getX

public ValueNode getX()

Description copied from interface: Canonicalizable.Binary

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

Specified by:

getX in interface Canonicalizable.Binary<ValueNode>

getY

public ValueNode getY()

Description copied from interface: Canonicalizable.Binary

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

Specified by:

getY in interface Canonicalizable.Binary<ValueNode>

Description copied from interface: Canonicalizable.Binary

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:
