Methods

Modifier and Type	Method and Description
abstract void	getVisiblePoints(double[] startPt, ArrayList<double[]> result) Develops a list of corner points or tangent points that are potentially visible from an input point--does include "standoff" in calculation (does not test whether other objects are in the way)
abstract String	toMATLABString() Generates a string representation of the Path object that can be used to plot the path in MATLAB
String	toString() Generates a string representation of the wall object

Constructor Detail

StationaryObject

public StationaryObject(double x,
                double y,
                double standoff)

Constructor

Parameters:

x - north/south Cartesian coordinate of the object's location in the world

y - east/west Cartesian coordinate of the object's location in the world

standoff - required distance (meters) that the vehicle must remain clear from this object

StationaryObject

public StationaryObject(double[] position,
                double standoff)

Constructor

Parameters:

position - 2-element array with the Cartesian coordinates of the object's location in the world

standoff - required distance (meters) that the vehicle must remain clear from this object

StationaryObject

public StationaryObject(Point position,
                double standoff)

Constructor

Parameters:

position - 2-element array with the Cartesian coordinates of the object's location in the world

standoff - required distance (meters) that the vehicle must remain clear from this object

Method Detail

getVisiblePoints

public abstract void getVisiblePoints(double[] startPt,
                    ArrayList<double[]> result)

Develops a list of corner points or tangent points that are potentially visible from an input point--does include "standoff" in calculation (does not test whether other objects are in the way)

Parameters:

startPt - Cartesian coordinates of the point being tested

result - container into which the computed points (double[2]) that can be reached from the test point without crossing the objects will be added

toMATLABString

public abstract String toMATLABString()

Generates a string representation of the Path object that can be used to plot the path in MATLAB

toString

public String toString()

Generates a string representation of the wall object

Overrides:

toString in class WorldObject
