Method Detail

getGridCoverageFactory

public static GridCoverageFactory getGridCoverageFactory(Hints hints)
                                                  throws FactoryRegistryException

Returns the first implementation of GridCoverageFactory matching the specified hints. If no implementation matches, a new one is created if possible or an exception is thrown otherwise.

Parameters:

hints - An optional map of hints, or null if none.

Returns:

The first grid coverage factory that matches the supplied hints.

Throws:

FactoryRegistryException - if no implementation was found or can be created for the GridCoverageFactory interface.

public static Set<GridCoverageFactory> getGridCoverageFactories(Hints hints)

Returns a set of all available implementations for the GridCoverageFactory interface.

Parameters:

hints - An optional map of hints, or null if none.

Returns:

Set of available grid coverage factory implementations.

scanForPlugins

public static void scanForPlugins()

Scans for factory plug-ins on the application class path. This method is needed because the application class path can theoretically change, or additional plug-ins may become available. Rather than re-scanning the classpath on every invocation of the API, the class path is scanned automatically only on the first invocation. Clients can call this method to prompt a re-scan. Thus this method need only be invoked by sophisticated applications which dynamically make new plug-ins available at runtime.
