Class ApacheCatalogResolver

public class ApacheCatalogResolver extends CatalogResolver

This class extends the CatalogResolver class provided by Norman Walsh's resolver library in xml-commons. It provides the bridge between the Ant XMLCatalog datatype and the xml-commons Catalog class. XMLCatalog calls methods in this class using Reflection in order to avoid requiring the xml-commons resolver library in the path.

The {@link org.apache.tools.ant.types.resolver.ApacheCatalog ApacheCatalog} class is used to parse external catalog files, which can be in either plain text format or XML format.

For each entry found in an external catalog file, if any, an instance of {@link org.apache.tools.ant.types.ResourceLocation ResourceLocation} is created and added to the controlling XMLCatalog datatype. In this way, these entries will be included in XMLCatalog's lookup algorithm. See XMLCatalog.java for more details.

Since: Ant 1.6

Method Summary
voidaddPublicEntry(String publicid, String systemid, URL base)

Add a PUBLIC catalog entry to the controlling XMLCatalog instance.

voidaddURIEntry(String uri, String altURI, URL base)

Add a URI catalog entry to the controlling XMLCatalog instance.

voidparseCatalog(String file)
XMLCatalog calls this to add an external catalog file for each file within a <catalogfiles> fileset.
voidsetXMLCatalog(XMLCatalog xmlCatalog)
Set the XMLCatalog object to callback.

Method Detail

addPublicEntry

public void addPublicEntry(String publicid, String systemid, URL base)

Add a PUBLIC catalog entry to the controlling XMLCatalog instance. ApacheCatalog calls this for each PUBLIC entry found in an external catalog file.

Parameters: publicid The public ID of the resource systemid The system ID (aka location) of the resource base The base URL of the resource. If the systemid specifies a relative URL/pathname, it is resolved using the base. The default base for an external catalog file is the directory in which the catalog is located.

addURIEntry

public void addURIEntry(String uri, String altURI, URL base)

Add a URI catalog entry to the controlling XMLCatalog instance. ApacheCatalog calls this for each URI entry found in an external catalog file.

Parameters: uri The URI of the resource altURI The URI to which the resource should be mapped (aka the location) base The base URL of the resource. If the altURI specifies a relative URL/pathname, it is resolved using the base. The default base for an external catalog file is the directory in which the catalog is located.

parseCatalog

public void parseCatalog(String file)
XMLCatalog calls this to add an external catalog file for each file within a <catalogfiles> fileset.

setXMLCatalog

public void setXMLCatalog(XMLCatalog xmlCatalog)
Set the XMLCatalog object to callback.
