Constructor Detail

StandardRelaxNGProvider

public StandardRelaxNGProvider()
                        throws SchemaServiceException

Default constructor which uses the default manifest file.

Throws:

SchemaServiceException - Thrown if the input files are not found or could not be loaded.

Method Detail

getSchema

public InputStream getSchema(String namespaceURI)
                      throws IOException

Description copied from interface: RelaxNGProvider

Provides a RelaxNG resource by its namespace URI. null is returned if there is no resource available for this namespace. If only the existence shall be checked, the call RelaxNGProvider.isAvailable(String) should be used. Note: The provider contains only "top-level" XMP schemas (such as Dublin Core) and no XMP type schemas (such as Dimensions).

Specified by:

getSchema in interface RelaxNGProvider

Parameters:

namespaceURI - the namespace URI of the schema according to the XMP specification

Returns:

Returns the RelaxNG resource as stream

Throws:

IOException - Forwards exceptions that occur during schema file loading.

RelaxNGProvider.getSchema(java.lang.String)

getInclude

public InputStream getInclude(String includeName)
                       throws IOException

Description copied from interface: RelaxNGProvider

Provides a RelaxNG include, referenced by its name

Specified by:

getInclude in interface RelaxNGProvider

Returns:

Returns the RelaxNG resource as stream or null if it has not been found.

Throws:

IOException - Forwards exceptions that occur during schema file loading.

See Also:

RelaxNGProvider.getInclude(java.lang.String)

isAvailable

public boolean isAvailable(String namespaceURI)

Description copied from interface: RelaxNGProvider

Checks if a schema (identified by its URI) can be provided. The result of this call has to be symmetric to RelaxNGProvider.getSchema(String). Note: For all namespaces where isAvailable() returns true, the method getSchema() has to return a result as well. Note: a call to this method should only check whether the RelaxNG resource is available, and should not already load the resource.

Specified by:

isAvailable in interface RelaxNGProvider

Parameters:

namespaceURI - the namespace URI of the schema according to the XMP specification

Returns:

Returns true if the schema is registered. This does not imply that it can be loaded successfully.

See Also:

RelaxNGProvider.isAvailable(java.lang.String)

getNamespaces

public Set<String> getNamespaces()

Description copied from interface: RelaxNGProvider

Returns a list of all schema namespaces that this provider can deliver.

Specified by:

getNamespaces in interface RelaxNGProvider

Returns:

Returns a list of all available schema namespaces of this provider.

See Also:

RelaxNGProvider.getNamespaces()

getRuntimeDecorators

public Map<XMPPath,Map<QName,Map<String,String>>> getRuntimeDecorators()

No default runtime decorators.

Specified by:

getRuntimeDecorators in interface RelaxNGProvider

Returns:
