public class Trace
extends Opcode

This class implements the Trace Opcode in the AAM. Trace sets or retrieves the current trace level (as a keyword).

 Example: (:TRACE ?oldvalue) (:TRACE :VERBOSE) ... (:TRACE ?oldvalue).
 
Possible values are :NORMAL, :VERBOSE, :DETAIL, :DEBUG and :ALWAYS

Constructor Detail

Trace

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

Method Detail

execute

public void execute(Processor processor,
                    AlgernonKBSet kbSet)
             throws AlgernonDataException
Executes the Trace opcode. This always succeeds, unless it throws an invalid value error. If ground, sets the trace level. If not ground, retrieves the trace level

Overrides:
execute in class Opcode
Throws:
AlgernonDataException
