public final class CachedAuthorityDecorator
extends AbstractAuthorityFactory
implements AuthorityFactory, CRSAuthorityFactory, CSAuthorityFactory, DatumAuthorityFactory, CoordinateOperationAuthorityFactory, BufferedFactory

An authority factory that caches all objects created by delegate factories. This class is set up to cache the full complement of referencing objects: In many cases a single implementation will be used for several the authority factory interfaces - but this is not a requirement. The behaviour of the createFoo(String) methods first looks if a previously created object exists for the given code. If such an object exists, it is returned directly. The testing of the cache is synchronized and may block if the referencing object is under construction.

If the object is not yet created, the definition is delegated to the appropriate the AuthorityFactory authority factory and the result is cached for next time.

This object is responsible for owning a {{ReferencingObjectCache}}; there are several implementations to choose from on construction.

Constructor Detail

CachedAuthorityDecorator

public CachedAuthorityDecorator(AuthorityFactory factory)

Constructs an instance wrapping the specified factory with a default cache.

The provided authority factory must implement DatumAuthorityFactory, CSAuthorityFactory, CRSAuthorityFactory and CoordinateOperationAuthorityFactory .

Parameters:

factory - The factory to cache. Can not be null.

CachedAuthorityDecorator

protected CachedAuthorityDecorator(AuthorityFactory factory,
                                   ObjectCache<Object,Object> cache)

Constructs an instance wrapping the specified factory. The maxStrongReferences argument specify the maximum number of objects to keep by strong reference. If a greater amount of objects are created, then the strong references for the oldest ones are replaced by weak references.

This constructor is protected because subclasses must declare which of the DatumAuthorityFactory, CSAuthorityFactory, CRSAuthorityFactory SearchableAuthorityFactory and CoordinateOperationAuthorityFactory interfaces they choose to implement.

Parameters:

factory - The factory to cache. Can not be null.

cache - The cache to use

Method Detail

Description copied from class: AbstractAuthorityFactory

Returns an arbitrary object from a code. The returned object will typically be an instance of Datum, CoordinateSystem, CoordinateReferenceSystem or CoordinateOperation. The default implementation always throw an exception. Subclasses should override this method if they are capable to automatically detect the object type from its code.

Specified by:

createObject in interface AuthorityFactory

Overrides:

Parameters:

code - Value allocated by authority.

Returns:

The object for the given code.

Description copied from class: AbstractAuthorityFactory

Creates an operation from coordinate reference system codes. The default implementation returns an empty set. We do not delegate to some kind of coordinate operation factory method because the usual contract for this method is to extract the information from an authority database like EPSG, not to compute operations on-the-fly.

Rational: Coordinate operation factory backed by an authority will invoke this method. If this method invoked the coordinate operation factory in turn, the application could be trapped in infinite recursive calls.

Specified by:

createFromCoordinateReferenceSystemCodes in interface CoordinateOperationAuthorityFactory

Overrides:

createFromCoordinateReferenceSystemCodes in class AbstractAuthorityFactory

Parameters:

sourceCode - Coded value of source coordinate reference system.

targetCode - Coded value of target coordinate reference system.

Returns:

The operations from sourceCRS to targetCRS.

Throws:

NoSuchAuthorityCodeException - if a specified code was not found.

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

getIdentifiedObjectFinder

public IdentifiedObjectFinder getIdentifiedObjectFinder(Class<? extends IdentifiedObject> type)
                                                 throws FactoryException

Description copied from class: AbstractAuthorityFactory

Returns a finder which can be used for looking up unidentified objects. The finder fetchs a fully identified object from an incomplete one, for example from an object without identifier or "AUTHORITY[...]" element in Well Known Text terminology.

Overrides:

getIdentifiedObjectFinder in class AbstractAuthorityFactory

Parameters:

type - The type of objects to look for. Should be a GeoAPI interface like GeographicCRS.class, but this method accepts also implementation class. If the type is unknown, use IdentifiedObject.class. A more accurate type may help to speed up the search, since it reduces the amount of tables to scan in some implementations like the factories backed by EPSG database.

Returns:

A finder to use for looking up unidentified objects.

Throws:

FactoryException - if the finder can not be created.

dispose

public void dispose()
             throws FactoryException

Description copied from class: AbstractAuthorityFactory

Releases resources immediately instead of waiting for the garbage collector. Once a factory has been disposed, further create(...) invocations may throw a FactoryException. Disposing a previously-disposed factory, however, has no effect.

Overrides:

dispose in class AbstractAuthorityFactory

Throws:

FactoryException - if an error occured while disposing the factory.

getBackingStoreDescription

public String getBackingStoreDescription()
                                  throws FactoryException

Description copied from class: AbstractAuthorityFactory

Returns a description of the underlying backing store, or null if unknown. This is for example the database software used for storing the data. The default implementation returns always null.

Overrides:

getBackingStoreDescription in class AbstractAuthorityFactory

Returns:

The description of the underlying backing store, or null.

Throws:

FactoryException - if a failure occurs while fetching the engine description.
