getEntryPaths

public java.util.Enumeration getEntryPaths(java.lang.String path)
Description copied from class: BundleFile
Allows to access the entries of the bundle. Since the bundle content is usually a jar, this allows to access the jar contents. GetEntryPaths allows to enumerate the content of "path". If path is a directory, it is equivalent to listing the directory contents. The returned names are either files or directories themselves. If a returned name is a directory, it finishes with a slash. If a returned name is a file, it does not finish with a slash.

Specified by:
getEntryPaths in class BundleFile
Parameters:
path - path of the entry to locate in the bundle
Returns:
an Enumeration of Strings that indicate the paths found or null if the path does not exist.
