boolean	inferStamp() This method can be overridden by subclasses of ValueNode if they need to recompute their stamp if their inputs change.

Method Detail

getOp

protected final ArithmeticOpTable.UnaryOp<OP> getOp(ValueNode forValue)

inferStamp

public boolean inferStamp()

Description copied from class: ValueNode

This method can be overridden by subclasses of ValueNode if they need to recompute their stamp if their inputs change. A typical implementation will compute the stamp and pass it to ValueNode.updateStamp(Stamp), whose return value can be used as the result of this method.

Overrides:

inferStamp in class ValueNode

Returns:

true if the stamp has changed, false otherwise.

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>
