Constructor Detail

PrimeMeridianRef

public PrimeMeridianRef(ReferenceResolver resolver,
                        String uri,
                        String baseURL)

Creates a reference to a IPrimeMeridian

Parameters:

resolver - used for resolving the reference, must not be null

uri - the object's uri, must not be null

baseURL - base URL for resolving the uri, may be null (no resolving of relative URLs)

Method Detail

getLongitude

public double getLongitude()

Specified by:

getLongitude in interface IPrimeMeridian

Returns:

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

getLongitude

public double getLongitude(IUnit targetUnit)

Specified by:

getLongitude in interface IPrimeMeridian

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

public double getLongitudeAsRadian()

Specified by:

getLongitudeAsRadian in interface IPrimeMeridian

Returns:

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

getAngularUnit

public IUnit getAngularUnit()

Specified by:

getAngularUnit in interface IPrimeMeridian

Returns:

the angular unit.

setAngularUnit

public void setAngularUnit(IUnit units)

Specified by:

setAngularUnit in interface IPrimeMeridian

Parameters:

units - to be used

setLongitude

public void setLongitude(double lon,
                         IUnit degree)

Specified by:

setLongitude in interface IPrimeMeridian

equals

public boolean equals(Object obj)

Overrides:

equals in class CRSResourceRef<IPrimeMeridian>
