# 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 jaxp.properties file to take advantage of the feature.

The XML Catalog API defines the following interfaces:

- `Catalog` -- The `Catalog` interface represents an entity catalog as defined by the Catalog standard. A `Catalog` object is immutable. Once created, it can be used to find matches in a `system`, `public` or `uri` entry. A custom resolver implementation may find it useful for locating local resources through a catalog.
- `CatalogFeatures` -- The `CatalogFeatures` class 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 `CatalogManager` class manages the creation of XML catalogs and catalog resolvers.
- `CatalogResolver` -- The `CatalogResolver` class is a `Catalog` resolver 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.
