public DefaultInternalAction()

Method Details

suspendIntention

public boolean suspendIntention()

Description copied from interface: InternalAction

Returns true if the internal action (IA) should suspend the intention where the IA is called

Specified by:

suspendIntention in interface InternalAction

canBeUsedInContext

public boolean canBeUsedInContext()

Description copied from interface: InternalAction

Return true if the internal action can be used in plans' context

Specified by:

canBeUsedInContext in interface InternalAction

getMinArgs

public int getMinArgs()

getMaxArgs

public int getMaxArgs()

checkArguments

protected void checkArguments(Term[] args)
                       throws JasonException

Throws:

JasonException

prepareArguments

public Term[] prepareArguments(Literal body,
 Unifier un)

Description copied from interface: InternalAction

Prepare body's terms to be used in 'execute', normally it consist of cloning and applying each term

Specified by:

prepareArguments in interface InternalAction

execute

public Object execute(TransitionSystem ts,
 Unifier un,
 Term[] args)
               throws Exception

Description copied from interface: InternalAction

Executes the internal action. It should return a Boolean or an Iterator. A true boolean return means that the IA was successfully executed. An Iterator result means that there is more than one answer for this IA (e.g. see member internal action).

Specified by:

execute in interface InternalAction

Throws:

Exception

destroy

public void destroy()
             throws Exception

Specified by:

destroy in interface InternalAction

Throws:

Exception
