Method Detail

getResourceDescription

public abstract MetadataRevisionNoteDescriptor.ResourceDescription getResourceDescription(MetadataRevisionNoteURI uri)

Returns the description of the resource identified by a MetadataRevisionNoteURI or null if this service cannot resolve the URI.

Parameters:

uri - the URI that identifies a resource associated with a metadata revision

Returns:

the description of the resource identified by the URI; null if this service cannot resolve the give URI

newServiceLoader

public static java.util.ServiceLoader<MetadataRevisionNoteDescriptor> newServiceLoader()

Creates a new loader for iterating through all available providers found by the context classloader. This is convenience method for creating a java.util.ServiceLoader instance for this class. Clients that need to resolve a list of MetadataRevisionNoteURI objects are recommended to create a loader only once and call resolve(Iterator, MetadataRevisionNoteURI) with a new iterator each time to improve performance.

Returns:

a new loader that loads all instances of this class found by the context classloader

resolve

public static MetadataRevisionNoteDescriptor.ResourceDescription resolve(java.util.Iterator<MetadataRevisionNoteDescriptor> iterator,
                                                                         MetadataRevisionNoteURI uri)

Resolves a MetadataRevisionNoteURI object using a list of MetadataRevisionNoteDescriptors. This method first consults MetadataRevisionSupport to see if a non-null ResourceDescription can be obtained; if so, the non-null ResourceDescription is returned immediately. If not, the first non-null ResourceDescription returned by a MetadataRevisionNoteDescriptor from the iterator is returned. If none of the MetadataRevisionNoteDescriptors can resolve the given URI, a default ResourceDescription whose subject is the String representation of the URI is returned.

Parameters:

iterator - the list of MetadataRevisionNoteDescriptors

uri - the URI to be resolved

Returns:

the first non-null ResourceDescription from MetadataRevisionSupport, the iterator or the default ResourceDescription whose subject is the String representation of the URI. This method never returns null.

resolve

public static MetadataRevisionNoteDescriptor.ResourceDescription resolve(MetadataRevisionNoteURI uri)

Resolves a MetadataRevisionNoteURI URI using a new ServiceLoader object. Clients should avoid using this method for resolution of multiple URIs to avoid the overhead of reloading the service providers each time.

Parameters:

uri - the URI to be resolved

Returns:

the description of the resource identified by the URI
