public class FactoryUsingWKT

extends DeferredAuthorityFactory

Implementation for a coordinate reference system authority factory backed by the EPSG property file. This factory is used as a fallback when no connection to an EPSG database is available. It search for a file named {@value} in the first of the following locations where such a file is found:

• (...todo...)
• directory in the classpath or in a JAR file.

Constructor Detail

FactoryUsingWKT

public FactoryUsingWKT()

Constructs an authority factory using the default set of factories.

FactoryUsingWKT

public FactoryUsingWKT(Hints hints)

Constructs an authority factory using a set of factories created from the specified hints. This constructor recognizes the CRS, CS, DATUM and MATH_TRANSFORM hints. In addition, the FactoryGroup.HINT_KEY hint may be used as a low-level substitute for all the above.

Method Detail

getAuthority

public org.opengis.metadata.citation.Citation getAuthority()

Returns the authority, which is EPSG.

Specified by:

getAuthority in interface org.opengis.referencing.AuthorityFactory

Overrides:

getAuthority in class BufferedAuthorityFactory

createBackingStore

protected AbstractAuthorityFactory createBackingStore()
                                               throws org.opengis.referencing.FactoryException

Creates the backing store authority factory. This method search for the {@value} file in all locations described in the class javadoc.

Specified by:

createBackingStore in class DeferredAuthorityFactory

Returns:

The backing store to uses in methods.

Throws:

org.opengis.referencing.FactoryException - if the constructor failed to find or read the file. This exception usually has an IOException as its cause.
