Parameters:

attrs - The attributes we want to fill with default values.

ext - The extension name.

into - The already built set of default values.

Returns:

A Hashtable, containing the augmented set of default attribute values.

 protected String[] getFileExtensions(String name)

 protected HTTPResource createFileResource(File directory,
                                           String name,

Parameters:

directory - The directory of the file.

name - The name of the file.

defs - A set of default attribute values.

Returns:

                                                Hashtable defs)

Create a default container resource for this directory (that exists).

Parameters:

directory - The parent directory.

name - The name of its sub-directory to index.

defaults - A set of default atribute values.

Returns:

An HTTP instance, or null if the indexer was unable to build a default resource for the directory.

 public HTTPResource createResource(ContainerResource container,
                                    Request request,
                                    File directory,

                                    Hashtable defs)

Try to create a resource for the given file. This method makes its best efforts to try to build a default resource out of a file.

Parameters:

directory - The directory the file is in.

name - The name of the file.

defs - Any default attribute values that should be provided to the created resource at initialization time.

Returns:

A Resource instance, or null if the given file can't be truned into a resource given our configuration database.
