AuthorityFactory, Factory

All Known Implementing Classes:

PseudoEpsgFactory

@UML(identifier="CS_CoordinateSystemAuthorityFactory",
     specification=OGC_01009)
public interface DatumAuthorityFactory
extends AuthorityFactory

Creates datum objects using authority codes. External authorities are used to manage definitions of objects used in this interface. The definitions of these objects are referenced using code strings. A commonly used authority is EPSG.

Method Details

createDatum

Datum createDatum(String code)
           throws NoSuchAuthorityCodeException,
FactoryException

Returns an arbitrary datum from a code.

If the datum type is known at compile time, then it is recommended to invoke the most precise method instead of this one. For example, it is usually better to invoke createGeodeticDatum(code) instead of createDatum(code) if the requested object is known to be a GeodeticDatum instance.

Parameters:

code - value allocated by authority.

Returns:

the datum for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

FactoryException - if the object creation failed for some other reason.

createEngineeringDatum

EngineeringDatum createEngineeringDatum(String code)
                                 throws NoSuchAuthorityCodeException,
FactoryException

Returns a engineering datum from a code.

Parameters:

code - value allocated by authority.

Returns:

the datum for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

FactoryException - if the object creation failed for some other reason.

createImageDatum

ImageDatum createImageDatum(String code)
                     throws NoSuchAuthorityCodeException,
