All Superinterfaces:

AuthorityFactory, Factory

All Known Implementing Classes:

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, which is also used in the GeoTIFF standard.

Method Details

createDatum

Datum createDatum(String code)
           throws NoSuchAuthorityCodeException,
FactoryException

Returns an arbitrary datum from a code. If the datum type is know at compile time, it is recommended to invoke the most precise method instead of this one (for example createGeodeticDatum(code) instead of createDatum(code) if the caller know he is asking for a geodetic datum).

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.

• createVerticalDatum(java.lang.String)
• createTemporalDatum(java.lang.String)

createEngineeringDatum

EngineeringDatum createEngineeringDatum(String code)
                                 throws NoSuchAuthorityCodeException,
FactoryException

Creates 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.

• CRSAuthorityFactory.createEngineeringCRS(java.lang.String)

createImageDatum

ImageDatum createImageDatum(String code)
                     throws NoSuchAuthorityCodeException,
FactoryException

Creates a image 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.

See Also:

• CRSAuthorityFactory.createImageCRS(java.lang.String)

createVerticalDatum

VerticalDatum createVerticalDatum(String code)
                           throws NoSuchAuthorityCodeException,
FactoryException

Creates a vertical 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.

• CRSAuthorityFactory.createVerticalCRS(java.lang.String)

createTemporalDatum

TemporalDatum createTemporalDatum(String code)
                           throws NoSuchAuthorityCodeException,
FactoryException

Creates a temporal 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.

See Also:

• CRSAuthorityFactory.createTemporalCRS(java.lang.String)

createGeodeticDatum

GeodeticDatum createGeodeticDatum(String code)
                           throws NoSuchAuthorityCodeException,
FactoryException

Returns a geodetic 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.
