public java.lang.String getFileName(java.net.URL url)
URLFileSystemHelper
URL
, not including any protocol, hostname authentication, directory path, anchor, or query. This simply returns the simple filename. For example, if you pass in an URL
whose string representation is:
protocol://host:1010/dir1/dir2/file.ext#anchor?query
the returned value is "file.ext
" (without the quotes).
The returned file name should only be used for display purposes and not for opening streams or otherwise trying to locate the resource indicated by the URL
.
getFileName
in class URLFileSystemHelper
public java.lang.String getPlatformPathName(java.net.URL url)
URLFileSystemHelper
URL
; the returned string should be considered acceptable for users to read. In general, the returned string should omit as many parts of the URL
as possible. For the "file" protocol, therefore, the platform pathname should just be the pathname alone (no protocol) using the appropriate file separator character for the current platform. For other protocols, it may be necessary to reformat the URL
string into a more human-readable form. That decision is left to each URLFileSystemHelper
implementor. The default implementation returns url.toString()
. If the URL
is null
, the empty string is returned.getPlatformPathName
