@ThreadSafe
public class WebCRSFactory
extends DirectAuthorityFactory
implements CRSAuthorityFactory

The factory for coordinate reference systems in the CRS namespace. The format is usually "CRS:n" where n is a number like 27, 83 or 84. However this factory is lenient and allows the CRS part to be repeated as in "CRS:CRS84". It also accepts "OGC" as a synonymous of the "CRS" namespace. Examples:

• "CRS:27"
• "CRS:83"
• "CRS:84"
• "CRS:CRS84"
• "OGC:CRS84"

Constructor Detail

WebCRSFactory

public WebCRSFactory()

Constructs a default factory for the CRS authority.

WebCRSFactory

public WebCRSFactory(Hints userHints)

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

Parameters:

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

Method Detail

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

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

Throws:

FactoryException

getDescriptionText

public InternationalString getDescriptionText(String code)
                                       throws FactoryException

Returns the CRS name for the given code.

Specified by:

getDescriptionText in interface AuthorityFactory

Throws:

FactoryException - if an error occurred while fetching the description.

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.

Throws:

FactoryException - if the object creation failed.

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:

FactoryException - if the object creation failed.
