Method Detail

clone

public Path clone()

Implements the Cloneable interface

Overrides:

clone in class Object

Returns:

a copy of this path

compareTo

public int compareTo(Path path2)

Implements the Comparable interface Compares this path to another link using the "cost" and "remaining" values for comparison

Specified by:

compareTo in interface Comparable<Path>

Returns:

-1, 0, or 1 if this object is "less than", "equal to" or "greater than" the link to which it is being compared

getCost

public double getCost()

Returns:

the cost to the vehicle to travel the path

getEstimatedRemaining

public double getEstimatedRemaining()

Returns:

the estimated minimum remaining cost from the path end point to the goal

addLink

public void addLink(PathLink newLink)

Adds a link to the end of the path and updates the estimates

Parameters:

newLink -

getLastPlannedPoint

public Point getLastPlannedPoint()

Returns:

the last point in the partial path

isLoop

public boolean isLoop()

Returns:

true if the endpoint of the path revisits any previously visited point

toMATLABString

public String toMATLABString()

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

generateAvclScriptElementList

public List<JAXBElement<?>> generateAvclScriptElementList(int vehicleType,
                                                 double gpsInterval,
                                                 double minWptDist,
                                                 double vertical,
                                                 int verticalMode,

                                                 int speedMode)

Generates a set of AVCL commands (waypoints) corresponding to the path

Parameters:

vehicleType - enumeration for the type of vehicle (UUV, USV, UGV or UAV)

gpsInterval - distance allowed between GPS fixes (UUV only)

minWptDist - minimum distance between waypoints

vertical - altitude or depth (UUV or UAV only)

verticalMode - enumeration determining how to interpret the vertical value

speed - speed to use in transit

speedMode - enumeration determining knots or meters per second

Returns:
