Package javax.xml.catalog
package javax.xml.catalog
Provides the classes for implementing
 
     XML Catalogs OASIS Standard V1.1, 7 October 2005.
 
The Catalog API defines a standard solution for resolving external resources referenced by XML documents. It is fully supported by the XML Processors allowing application developers to configure a catalog through an XML processor or system property or the configuration file to take advantage of the feature.
The XML Catalog API defines the following interfaces:
- Catalog-- The- Cataloginterface represents an entity catalog as defined by the Catalog standard. A- Catalogobject is immutable. Once created, it can be used to find matches in a- system,- publicor- urientry. A custom resolver implementation may find it useful for locating local resources through a catalog.
- CatalogFeatures-- The- CatalogFeaturesclass holds all of the features and properties the Catalog API supports, including- javax.xml.catalog.files,- javax.xml.catalog.defer,- javax.xml.catalog.prefer, and- javax.xml.catalog.resolve.
- CatalogManager-- The- CatalogManagerclass manages the creation of XML catalogs and catalog resolvers.
- CatalogResolver-- The- CatalogResolverclass is a- Catalogresolver that implements- EntityResolver,- XMLResolver,- LSResourceResolver, and- URIResolver, and resolves external references using catalogs.
 Unless otherwise noted, passing a null argument to
 a constructor or method in any class or interface in this package will
 cause a NullPointerException to be thrown.
