Class AblePlanningHTNProblemBuilder

java.lang.Object
  com.ibm.able.rules.AblePlanningHTNProblemBuilder

All Implemented Interfaces:

java.io.Serializable

public class AblePlanningHTNProblemBuilder

extends java.lang.Object

implements java.io.Serializable

This class builds a HTN Planning problem by processing a set of planning rules in a ruleblock.

The AblePlanningEngine processes AbleAssertionRules and AblePlanningRules and ignores all others. The AblePlanningHTNProblemBuilder is called by it to build the HTN problem.

The control parameters ARL.InitialState and ARL.GoalState can be used to specify the initial and final states respectively. The control parameter ARL.Domain can be used to specify the planning domain.

The control parameter ARL.Requirements can be used to specify requirements on the planning engine for the specified domain.

Instance of this class is constructed and used by AblePlanningEngine.

AblePlanningHTNProblemBuilder

public AblePlanningHTNProblemBuilder(AblePlanningEngine theEngine,
                                     AbleRuleSet theRuleSet,
                                     AbleLogger theTracer,
                                     AbleRuleBlock theRuleBlock)

Create a new planning inference engine.

Parameters:

theEngine - A planning engine will calls the builder.

theRuleSet - A ruleset whose context is used for inferencing by this inference engine.

theTracer - A tracer object to which this inference engine can log information. This may be null, in which case no information is logged.

theRuleBlock - A ruleblock whose rules are to be used for inferencing by this inference engine.
