Detailed Description

A class that defines the Manhattan heuristic function for a map pathfinding domain.

Constructor & Destructor Documentation

MapManhattanDistance::MapManhattanDistance ( )

Constructor for a MapManhattanDistance heuristic function. By default, sets the goal at (0, 0)

MapManhattanDistance::~MapManhattanDistance ( )

virtual

Destructor for a ManhattanDistance heuristic function. Does nothing.

double MapManhattanDistance::computeHValue ( const MapLocation & state ) const

protectedvirtual

Calculates the heuristic value of the given state. Does not store the heuristic value.

If the heuristic value is negative, the heuristic function is indicating unsolvability.

This is the main function to be overloaded.

Parameters

state The state whose heuristic value is to be calculated.

void MapManhattanDistance::setGoal ( const MapLocation & state )

Sets the goal location to the given map location.

Parameters

state The new goal.

void MapManhattanDistance::setGoal	(	uint16_t	x_loc,
		uint16_t	y_loc
	)

Sets the goal to use the given coordinates.

Parameters

x_loc	The x location of the goal.
y_loc	The y location of the goal.

MapLocation MapManhattanDistance::goal

protected

The goal location currently being used.
