Field Detail

GREENWICH

public static final PrimeMeridian GREENWICH

The Greenwich meridian, with angular measures in degrees.

Constructor Detail

PrimeMeridian

public PrimeMeridian(String name,
                     Unit unit,
                     double longitude)

Creates a prime meridian, relative to Greenwich.

Parameters:

name - Name to give new object.

unit - Angular units of longitude.

longitude - Longitude of prime meridian in supplied angular units East of Greenwich.

PrimeMeridian

PrimeMeridian(Map properties,
              Unit unit,
              double longitude)

Creates a prime meridian, relative to Greenwich.

Parameters:

properties - The set of properties (see Info).

unit - Angular units of longitude.

longitude - Longitude of prime meridian in supplied angular units East of Greenwich.

Method Detail

getLongitude

public double getLongitude()

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

Returns:

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

See Also:

"org.opengis.cs.CS_PrimeMeridian#getLongitude()"

getLongitude

public double getLongitude(Unit targetUnit)

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 units of this prime meridian.

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 units of this prime meridian.

getAngularUnit

public Unit getAngularUnit()

Returns the angular units.

Returns:

the angular units.

See Also:

"org.opengis.cs.CS_PrimeMeridian#getAngularUnit()"

hashCode

public int hashCode()

Returns a hash value for this prime meridian.

Overrides:

hashCode in class Info

Returns:

a hash value for this prime meridian.

equals

public boolean equals(Object object)

Compares the specified object with this prime meridian for equality.

Overrides:

equals in class Info

Returns:

addString

String addString(StringBuffer buffer)

Fill the part inside "[...]". Used for formatting Well Know Text (WKT).

Parameters:

buffer -
