Method Detail

• registerEntityId

  public void registerEntityId(String publicId,
                      URL entityURL)

  Registers the specified URL for the specified public identifier.

  This implementation maps PUBLICID's to URLs (from which the resource will be loaded). A common use case for this method is to register local URLs (possibly computed at runtime by a class loader) for DTDs and Schemas. This allows the performance advantage of using a local version without having to ensure every SYSTEM URI on every processed XML document is local. This implementation provides only basic functionality. If more sophisticated features are required, either calling XMLConfiguration.setDocumentBuilder(DocumentBuilder) to set a custom DocumentBuilder (which also can be initialized with a custom EntityResolver) or creating a custom entity resolver and registering it with the XMLConfiguration is recommended.

  Specified by:

  registerEntityId in interface EntityRegistry

  Parameters:

  publicId - Public identifier of the Entity to be resolved

  entityURL - The URL to use for reading this Entity

  Throws:

  IllegalArgumentException - if the public ID is undefined

• resolveEntity

  public InputSource resolveEntity(String publicId,
                          String systemId)
                            throws SAXException

  Resolves the requested external entity. This is the default implementation of the EntityResolver interface. It checks the passed in public ID against the registered entity IDs and uses a local URL if possible.

  Specified by:

  resolveEntity in interface EntityResolver

  Parameters:

  publicId - the public identifier of the entity being referenced

  systemId - the system identifier of the entity being referenced

  Returns:

  an input source for the specified entity

  Throws:

  SAXException - if a parsing exception occurs

• getRegisteredEntities

  public Map<String,URL> getRegisteredEntities()

  Returns a map with the entity IDs that have been registered using the registerEntityId() method.

  Specified by:

  getRegisteredEntities in interface EntityRegistry

  Returns:

  a map with the registered entity IDs
