Method Detail

getLongitude

double getLongitude()

Returns:

the longitude value relative to the Greenwich Meridian. The longitude is expressed in this objects angular units.

getLongitude

double getLongitude(IUnit targetUnit)

Parameters:

targetUnit - The unit in which to express longitude.

Returns:

the longitude value relative to the Greenwich Meridian, expressed in the specified units. This convenience method make easier to obtains longitude in degrees (getLongitude(Unit.DEGREE)), no matter the underlying angular unit of this prime meridian.

getLongitudeAsRadian

double getLongitudeAsRadian()

Returns:

the longitude value relative to the Greenwich Meridian, expressed in the radians.

getAngularUnit

IUnit getAngularUnit()

Returns:

the angular unit.

setAngularUnit

void setAngularUnit(IUnit units)

Parameters:

units - to be used

setLongitude

void setLongitude(double lon,
                  IUnit degree)

Parameters:

lon -

degree -
