CachedCRSAuthorityDecorator
public final class CachedCRSAuthorityDecorator
An authority factory that caches all objects created by the delegate CRSAuthorityFactory.
The behaviour of thecreateFoo(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 |

public CachedCRSAuthorityDecorator(CRSAuthorityFactory factory)
The provided authority factory must implement
DatumAuthorityFactory
, CSAuthorityFactory
,
CRSAuthorityFactory
and
CoordinateOperationAuthorityFactory
.
factory
- The factory to cache. Can not be null
.protected CachedCRSAuthorityDecorator(CRSAuthorityFactory factory, ObjectCache cache)
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.

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.
FactoryException
- if the finder can not be created.
