Constructor Details

WebCRSFactory

public WebCRSFactory()

Constructs a default factory for the CRS authority.

WebCRSFactory

public WebCRSFactory(Hints hints)

Constructs a factory for the CRS authority using the specified hints.

Method Details

getAuthority

public Citation getAuthority()

Returns the authority for this factory, which is CRS.

Specified by:

getAuthority in interface AuthorityFactory

Specified by:

getAuthority in class AbstractAuthorityFactory

Returns:

The organization reponsible for definition of the database.

getAuthorityCodes

public Set<String> getAuthorityCodes(Class<? extends IdentifiedObject> type)
                              throws FactoryException

Provides a complete set of the known codes provided by this authority. The returned set contains only numeric identifiers like "84", "27", etc. The authority name ("CRS") is not included. This is consistent with the codes returned by the EPSG factory and avoid duplication, since the authority is the same for every codes returned by this factory. It also make it easier for clients to prepend whatever authority name they wish, as for example in the all authorities factory.

Specified by:

getAuthorityCodes in interface AuthorityFactory

Parameters:

type - The spatial reference objects type.

Returns:

The set of authority codes for spatial reference objects of the given type. If this factory doesn't contains any object of the given type, then this method returns an empty set.

Throws:

FactoryException - if access to the underlying database failed.

getDescriptionText

public InternationalString getDescriptionText(String code)
                                       throws FactoryException

Returns the CRS name for the given code.

Specified by:

getDescriptionText in interface AuthorityFactory

Parameters:

code - Value allocated by authority.

Returns:

A description of the object, or null if the object corresponding to the specified code has no description.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

FactoryException - if the query failed for some other reason.

createObject

public IdentifiedObject createObject(String code)
                              throws FactoryException

Creates an object from the specified code. The default implementation delegates to createCoordinateReferenceSystem(code).

Specified by:

createObject in interface AuthorityFactory

Overrides:

createObject in class AbstractAuthorityFactory

Parameters:

code - Value allocated by authority.

Returns:

The object for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

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

createCoordinateReferenceSystem

public CoordinateReferenceSystem createCoordinateReferenceSystem(String code)
                                                          throws FactoryException

Creates a coordinate reference system from the specified code.

Specified by:

createCoordinateReferenceSystem in interface CRSAuthorityFactory

Overrides:

createCoordinateReferenceSystem in class AbstractAuthorityFactory

Parameters:

code - Value allocated by authority.

Returns:

The coordinate reference system for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

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