  edu.umich.soar.hpp.HPPAction

public class HPPAction
extends java.lang.Object

A plan action that supports arbitrary hierarchy via sub-plans and conditionality based upon a conjunctive set of variable name/value pairs.

Constructor Summary

HPPAction(java.lang.String name, HPPConstraint[] conditions, HPPlan subPlan)
Advanced constructor - supports custom initial condition set via array

HPPAction(java.lang.String name, HPPlan subPlan)
Basic constructor - initializes to empty condition set

Method Summary

void	addCondition(HPPConstraint newConstraint) Support appending to the condition set
java.util.Iterator<HPPConstraint>	getConditions() Supports read-only access to condition set
java.lang.String	getName() Supports read-only access to the action name
HPPlan	getSubPlan() Supports read-only access to the sub-plan
boolean	isSatisfied(HPPKnowledgeBase kb) Evaluates satisfaction of the action relative to a supplied knowledge base
