public class LongitudeFirstFactory
extends DeferredAuthorityFactory
implements CRSAuthorityFactory, CSAuthorityFactory, CoordinateOperationAuthorityFactory, DatumAuthorityFactory

An EPSG authority factory using (longitude, latitude) axis order. This factory wraps a ThreadedEpsgFactory into an OrderedAxisAuthorityFactory when first needed.

Users don't need to create explicitly an instance of this class. Instead, one can get an instance using the following code:

 Hints hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE);
 CRSAuthorityFactory factory = ReferencingFactoryFinder.getCRSAuthorityFactory("EPSG", hints);
 

Since:

2.3

Field Detail

SYSTEM_DEFAULT_KEY

public static final String SYSTEM_DEFAULT_KEY

Deprecated. Moved to GeoTools.FORCE_LONGITUDE_FIRST_AXIS_ORDER.

The system property key for setting the default FORCE_LONGITUDE_FIRST_AXIS_ORDER hint value. This setting can provide a transition path for projects expecting a (longitude, latitude) axis order on a system-wide level. Application developpers can set the default value as below:

 System.setProperty(SYSTEM_DEFAULT_KEY, "true");
 

Note that this system property applies mostly to the default EPSG factory. Most other factories ("CRS", "AUTO", etc.) don't need this property since they use (longitude, latitude) axis order by design.

Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Constant Field Values

Constructor Detail

LongitudeFirstFactory

public LongitudeFirstFactory()

Creates a default factory. The FORCE_LONGITUDE_FIRST_AXIS_ORDER hint is always set to TRUE. The FORCE_STANDARD_AXIS_DIRECTIONS and FORCE_STANDARD_AXIS_UNITS hints are set to FALSE by default. A different value for those two hints can be specified using the constructor below.

LongitudeFirstFactory

public LongitudeFirstFactory(Hints userHints)

Creates a factory from the specified set of hints.

Parameters:

userHints - An optional set of hints, or null for the default values.

Method Detail

getAuthority

public Citation getAuthority()

Returns the authority for this EPSG database. This authority will contains the database version in the edition attribute, together with the edition date.

Specified by:

getAuthority in interface AuthorityFactory

Overrides:

getAuthority in class BufferedAuthorityFactory

Returns:

The organization reponsible for definition of the database.

createBackingStore

protected AbstractAuthorityFactory createBackingStore()
                                               throws FactoryException

Returns the factory instance (usually ThreadedEpsgFactory) to be used as the backing store.

Specified by:

createBackingStore in class DeferredAuthorityFactory

Returns:

The backing store to uses in createXXX(...) methods.

Throws:

FactoryException - If no suitable factory instance was found.
