navigate

public DataResource navigate(String relativePath)
                      throws ResourceUriUndefinedException

This method creates a new DataResource pointing to the given resourcePath based on this resource.
E.g. if this resource points to the file "/etc/init.d/rc" and relativePath would be "../apt/sources.list" the resulting resource would point to "/etc/apt/sources.list".

Specified by:

navigate in interface DataResource

Overrides:

navigate in class AbstractDataResourceProxy

Parameters:

relativePath - is the absolute or relative path pointing to a new resource. If it is a relative path, it is interpreted relative to the parent URI (directory) of this resource.

Returns:

is the resource pointing to the given path (relative to this resource).

Throws:

ResourceUriUndefinedException - if the given resourcePath leads to an undefined or illegal URI.
