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 jaxp.properties file to take advantage of the feature.
The XML Catalog API defines the following interfaces:
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
urientry. A custom resolver implementation may find it useful for locating local resources through a catalog.
CatalogFeaturesclass holds all of the features and properties the Catalog API supports, including
CatalogManagerclass manages the creation of XML catalogs and catalog resolvers.
CatalogResolverclass is a
Catalogresolver that implements
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
NullPointerException to be thrown.
