MultiAuthoritiesFactory

All Implemented Interfaces:

AuthorityFactory, CRSAuthorityFactory, CSAuthorityFactory, DatumAuthorityFactory, CoordinateOperationAuthorityFactory, Factory

public class MultiAuthoritiesFactory
extends GeodeticAuthorityFactory
implements CRSAuthorityFactory, CSAuthorityFactory, DatumAuthorityFactory, CoordinateOperationAuthorityFactory

A factory that delegates the object creation to another factory determined from the authority part in “authority:code” arguments. The list of factories to use as delegates can be specified at construction time.

This factory requires that every codes given to a create­Foo(String) method are prefixed by a namespace, for example "EPSG:4326" or "EPSG::4326". When a create­Foo(String) method is invoked, this class uses the authority part in the “authority:code” argument for locating a factory capable to create a geodetic object for the code part. If a factory is found in the list of factories given at construction time, then the work is delegated to that factory. Otherwise a No­Such­Authority­Factory­Exception is thrown.

URI syntax

This factory can also parse URNs or URLs of the following forms:

• "urn:ogc:def:type:authority:version:code"
• "http://www.opengis.net/def/type/authority/version/code"
• "http://www.opengis.net/gml/srs/authority.xml#code"

In such cases, the type specified in the URN may be used for invoking a more specific method. However Multi­Authorities­Factory uses the type information in the URN only for delegating to a more specific method, never for delegating to a less specific method. An exception will be thrown if the type in the URN is incompatible with the invoked method.

Example: if create­Object("urn:ogc:def:crs:EPSG::4326") is invoked, then Multi­Authorities­Factory will delegate (indirectly, ignoring caching for this example) the object creation to EPSGData­Access.create­Coordinate­Reference­System(String) instead of EPSGData­Access.create­Object(String) because of the "crs" part in the URN. The more specific method gives better performances and avoid ambiguities.

This class accepts also combined URIs of the following forms (only two components shown, but arbitrary number of components is allowed):

• "urn:ogc:def:type, type₁:authority₁:version₁:code₁, type₂:authority₂:version₂:code₂"
• "http://www.opengis.net/def/crs-compound?
1=http://www.opengis.net/def/crs/authority₁/version₁/code₁&
2=http://www.opengis.net/def/crs/authority₂/version₂/code₂"

Given such URIs, Multi­Authorities­Factory invokes create­Object(String) for each component and combines the result as described by the CRS.compound(Coordinate­Reference­System...) method. URNs (but not URLs) can also combine a geodetic datum with an ellipsoidal coordinate system for creating a new geographic CRS, or a base geographic CRS with a conversion and a Cartesian coordinate system for creating a new projected coordinate reference system, or coordinate operations for creating a concatenated operation.

Multiple versions for the same authority

Multi­Authorities­Factory accepts an arbitrary amount of factories for the same authority, provided that those factories have different version numbers. If a create­Foo(String) method is invoked with a URN containing a version number different than zero, then Multi­Authorities­Factory will search for a factory with that exact version, or throw a No­Such­Authority­Factory­Exception if no suitable factory is found. If a create­Foo(String) method is invoked with the version number omitted, then Multi­Authorities­Factory will use the first factory in iteration order for the requested authority regardless of its version number.

Example: a Multi­Authorities­Factory instance could contain two EPSGFactory instances: one for version 8.2 and another one for version 7.9 of the EPSG dataset. A specific version can be requested in the URN given to create­Foo(String) methods, for example "urn:ogc:def:crs:EPSG:8.2:4326". If no version is given of if the given version is zero, then the first EPSG factory in iteration order is used regardless of its version number.

Multi-threading

This class is thread-safe if all delegate factories are themselves thread-safe. However the factory providers, which are given to the constructor as Iterable instances, do not need to be thread-safe. See constructor Javadoc for more information.

Constructor Detail

MultiAuthoritiesFactory

public MultiAuthoritiesFactory(Iterable<? extends CRSAuthorityFactory> crsFactories,
                               Iterable<? extends CSAuthorityFactory> csFactories,
                               Iterable<? extends DatumAuthorityFactory> datumFactories,
                               Iterable<? extends CoordinateOperationAuthorityFactory> copFactories)

Creates a new multi-factories instance using the given lists of factories. Calls to create­Foo(String) methods will scan the supplied factories in their iteration order when first needed. The first factory having the requested namespace will be used.

Requirements

Multi­Authorities­Factory may iterate over the same Iterable more than once. Each iteration shall return the same instances than previous iterations, unless reload() has been invoked.

The Iterables do not need to be thread-safe. Multi­Authorities­Factory will use them only in blocks synchronized on the Iterable instance. For example all usages of crs­Factory will be done inside a synchronized(crs­Factory) block.

Name collision

If an Iterable contains more than one factory for the same namespace and version, then only the first occurrence will be used. All additional factories for the same namespace and version will be ignored, after a warning has been logged.

Caching

Multi­Authorities­Factory caches the factories found from the given Iterables, but does not cache the objects created by those factories. This constructor assumes that the given factories already do their own caching.

Parameters:

crs­Factories - the factories for creating Coordinate­Reference­System objects, or null if none.

cs­Factories - the factories for creating Coordinate­System objects, or null if none.

datum­Factories - the factories for creating Datum objects, or null if none.

cop­Factories - the factories for creating Coordinate­Operation objects, or null if none.

Method Detail

isLenient

public boolean isLenient()

Returns whether this factory should relax some rules when processing a given authority code. If this value is true, then the behavior of this Multi­Authorities­Factory is changed as below:

• If a version is specified in a URN but there is no factory for that specific version, then fallback on a factory for the same authority but the default version.

The default value is false, which means that an exception will be thrown if there is no factory specifically for the requested version.

Returns:

whether this factory should relax some rules when processing a given authority code.

setLenient

public void setLenient(boolean lenient)

Sets whether this factory should relax some rules when processing a given code.

Parameters:

lenient - whether this factory should relax some rules when processing a given authority code.

getAuthority

public Citation getAuthority()

Returns the database or specification that defines the codes recognized by this factory. The default implementation returns null since Multi­Authorities­Factory is not about a particular authority.

Specified by:

get­Authority in interface Authority­Factory

Specified by:

get­Authority in class Geodetic­Authority­Factory

Returns:

the organization responsible for definition of the database, or null if unknown.

See Also:

Abstract­Factory.get­Vendor()

getAuthorityCodes

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

Returns the set of authority codes for objects of the given type. This method returns the union of codes returned by all factories specified at construction time.

The Set.contains(Object) method of the returned set is lenient: it accepts various ways to format a code even if the iterator returns only one form. For example the contains(Object) method may return true for "EPSG:4326", "EPSG::4326", "urn:ogc:def:crs:EPSG::4326", etc. even if the iterator returns only "EPSG:4326".

Warnings:

• Callers should not retain a reference to the returned collection for a long time, since it may be backed by database connections (depending on the factory implementations).
• The returned set is not thread-safe. Each thread should ask its own instance and let the garbage collector disposes it as soon as the collection is not needed anymore.
• Call to the Set.size() method on the returned collection should be avoided since it may be costly.

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.

Throws:

Factory­Exception - if access to an underlying factory failed.

getCodeSpaces

public Set<String> getCodeSpaces()

Returns the code spaces of all factories given to the constructor.

Implementation note: the current implementation may be relatively costly since it implies instantiation of all factories.

Overrides:

get­Code­Spaces in class Geodetic­Authority­Factory

Returns:

the code spaces of all factories.
