Constructor Detail

Query

public Query(Algernon algy,
             String name,
             int numArgs)
Create a new AAM :QUERY Opcode.

Method Detail

execute

public void execute(Processor processor,
                    AlgernonKBSet kbSet)
             throws AlgernonException
Executes the QUERY opcode. If the clause in the CLAUSE register is not ground, it queries the knowledge base(s) for clauses that match the given clause. If the relation name is the name slot, the frame name may be a variable.

Overrides:
execute in class Opcode
Throws:
AlgernonException
