Method Detail
catalog
public static Catalog catalog(CatalogFeatures features, URI... uris)
Creates a Catalog
object using the specified feature settings and uri(s) to one or more catalog files.
If uris
is empty, system property javax.xml.catalog.files
, as defined in CatalogFeatures
, will be read to locate the initial list of catalog files.
If multiple catalog files are specified through the uris
argument or javax.xml.catalog.files
property, the first entry is considered the main catalog, while others are treated as alternative catalogs after those referenced by the nextCatalog
elements in the main catalog.
As specified in XML Catalogs, OASIS Standard V1.1, if a catalog entry is invalid, it is ignored. In case all entries are invalid, the resulting Catalog object will contain no Catalog elements. Any matching operation using the Catalog will return null.
- Parameters:
-
features
- the catalog features -
uris
- uri(s) to one or more catalogs. - Returns:
- an instance of a
Catalog
- Throws:
-
IllegalArgumentException
- if either the URIs are not absolute or do not have a URL protocol handler for the URI scheme -
CatalogException
- If an error occurs while parsing the catalog -
SecurityException
- if access to the resource is denied by the security manager
catalogResolver
public static CatalogResolver catalogResolver(Catalog catalog)
Creates an instance of a CatalogResolver
using the specified catalog.
- Parameters:
-
catalog
- the catalog instance - Returns:
- an instance of a
CatalogResolver
catalogResolver
public static CatalogResolver catalogResolver(CatalogFeatures features, URI... uris)
Creates an instance of a CatalogResolver
using the specified feature settings and uri(s) to one or more catalog files.
If uris
is empty, system property javax.xml.catalog.files
, as defined in CatalogFeatures
, will be read to locate the initial list of catalog files.
If multiple catalog files are specified through the uris
argument or javax.xml.catalog.files
property, the first entry is considered the main catalog, while others are treated as alternative catalogs after those referenced by the nextCatalog
elements in the main catalog.
As specified in XML Catalogs, OASIS Standard V1.1, if a catalog entry is invalid, it is ignored. In case all entries are invalid, the resulting CatalogResolver object will contain no valid catalog. Any resolution operation using the resolver therefore will return as no mapping is found. See CatalogResolver
for the behavior when no mapping is found.
- Parameters:
-
features
- the catalog features -
uris
- the uri(s) to one or more catalogs - Returns:
- an instance of a
CatalogResolver
- Throws:
-
IllegalArgumentException
- if either the URIs are not absolute or do not have a URL protocol handler for the URI scheme -
CatalogException
- If an error occurs while parsing the catalog -
SecurityException
- if access to the resource is denied by the security manager
