Method Summary

Modifier and Type	Method and Description
Node	canonical(CanonicalizerTool tool, Node 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.
LogicNode	condition()
Node	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).
boolean	isNegated()
void	lower(LoweringTool tool) Expand this node into lower level nodes expressing the same semantics.
String	toString(Verbosity verbosity) Creates a String representation for this with a given Verbosity.

condition

public LogicNode condition()

isNegated

public boolean isNegated()

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this with a given Verbosity.

Overrides:

toString in class Node

canonical

public Node canonical(CanonicalizerTool tool,
                      Node 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<Node>

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

getValue

public Node 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<Node>
