Constructor and Description
ShortCircuitOrNode(LogicNode x, boolean xNegated, LogicNode y, boolean yNegated, double shortCircuitProbability)

Method Summary

Modifier and Type	Method and Description
LogicNode	canonical(CanonicalizerTool tool, LogicNode forX, LogicNode forY) 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.
protected ShortCircuitOrNode	canonicalizeNegation(LogicNode forX, LogicNode forY)
double	getShortCircuitProbability() Gets the probability that the y part of this binary node is not evaluated.
LogicNode	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).
LogicNode	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

getX

public LogicNode 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<LogicNode>

getY

public LogicNode 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<LogicNode>

isXNegated

public boolean isXNegated()

isYNegated

public boolean isYNegated()

getShortCircuitProbability

public double getShortCircuitProbability()

Gets the probability that the y part of this binary node is not evaluated. This is the probability that this operator will short-circuit its execution.

canonicalizeNegation

protected ShortCircuitOrNode canonicalizeNegation(LogicNode forX,
                                                  LogicNode forY)

canonical

                           LogicNode forX,
                           LogicNode forY)

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:

canonical in interface Canonicalizable.Binary<LogicNode>
