public class TestUnbound

extends Opcode

This class represents a Test Opcode in the AAM. The system should only need to make one instance of this.

Constructor Summary

TestUnbound(Algernon algy, String name, int numArgs)
Create a new AAM :TEST Opcode.

Method Summary

void	execute(Processor processor, AlgernonKBSet kbSet) Checks the variable in the clause and sets result to NIL if it is bound, where it is checked by the :FAIL operator.

Constructor Detail

TestUnbound

public TestUnbound(Algernon algy,
                   String name,
                   int numArgs)

Create a new AAM :TEST Opcode.

Method Detail

execute

public void execute(Processor processor,
                    AlgernonKBSet kbSet)

Checks the variable in the clause and sets result to NIL if it is bound, where it is checked by the :FAIL operator. Don't need :BRANCH :SELECT after this opcode.

Overrides:
