Constructor Details

AbstractPlan

protected AbstractPlan()

Creates a new empty search. The plan created is noy hierarchical.

AbstractPlan

protected AbstractPlan(Plan other)

Creates a new search from an other one. The new search is a deep copy of the specified search in parameter.

Parameters:

other - the plan on which a deep copy is done.

Method Details

size

public final int size()

Returns the size of the search. The size of the search is its number of actions.

Specified by:

size in interface Plan

Returns:

the size of the search.

cost

public double cost()

Returns the cost of the search. The cost of a search is the sum of the cost of its actions.

Specified by:

cost in interface Plan

Returns:

the cost of the search.

isEmpty

public final boolean isEmpty()

Returns if the search is empty.

Specified by:

isEmpty in interface Plan

Returns:

true if the search is empty; false otherwise.

See Also:

Plan.isEmpty()

isHierarchical

public final boolean isHierarchical()

Returns if this plan is hierarchical.

Specified by:

isHierarchical in interface Plan

Returns:

true if this plan is hierarchical; false otherwise.

getHierarchy

public final Hierarchy getHierarchy()

Returns the hierarchy of this plan. The hierarchy is additional information produced by HTN planners to specified the hierarchical decomposition of the initial task networks into primitive tasks applied to produce a plan.

Specified by:

getHierarchy in interface Plan

Returns:

the hierarchical decomposition of this plan or null is this plan is not hierarchical.

See Also:

Plan.isHierarchical()

setHierarchy

public final void setHierarchy(Hierarchy hierarchy)

Sets the hierarchy of this plan. The hierarchy is additional information produced by HTN planners to specified the hierarchical decomposition of the initial task networks into primitive tasks applied to produce a plan.

Specified by:

setHierarchy in interface Plan

Parameters:

hierarchy - the hierarchical decomposition of this plan.

Plan.isHierarchical()
