Vector constructor

Parameters:

vector - { lat, lon, rad }

Method Detail

invalidate

public void invalidate()

Mark all members as invalid

getLatitude

public double getLatitude()

Get the latitude

Returns:

The latitude value of this instance

getX

public double getX()

Get the X element

Returns:

The X value (in XYZ vector form) of this instance

getLongitude

public double getLongitude()

Get the longitude

Returns:

The longitude value of this instance

getY

public double getY()

Get the Y element

Returns:

The Y value (in XYZ vector form) of this instance

getRadius

public double getRadius()

Get the radius

Returns:

get

public double[] get()

Get all values in this instance as a vector.

The vector is an array of three doubles, latitude, longitude, and radius, in that order.

Returns:

v[0] = latitude, v[1] = longitude, v[2] = radius

setLatitude

public void setLatitude(double d)

Set the latitude

Parameters:

d - The new latitude value

setLongitude

public void setLongitude(double d)

Set the longitude

Parameters:

d - The new longitude value

setRadius

public void setRadius(double d)

Set the radius

Parameters:

d - The new radius value

set

public void set(double[] vector)

Set all members of this instance from a vector.

The vector is an array of three doubles, latitude, longitude, and radius, in that order.

Parameters:

vector - v[0] = latitude, v[1] = longitude, v[2] = radius

set

public void set(double lat,
                double lon,
                double rad)

Set all members of this instance individually

Parameters:

lat - The new latitude

lon - The new longitude

rad - The new radius
