computeSafePath

public static File computeSafePath(File base,
 String pathName)

Compute a good file system location for a possibly path style name relative to some base folder. That is: Slashes will be kept in the path name but characters in path segments will be replaced if considered problematic. Furthermore, the first path segment will be augmented by a hash representation of the initial path name to ensure uniqueness. This method is not transitive, i.e.

 computeSafePath(base,"a/b")
 

is not equal to

 computeSafePath(new File(base,"a"),"b")
 

Parameters:

base -

pathName -

Returns:
