rename

String rename(String currentPath,

              throws RegistryException

Rename a resource in the registry. This is equivalent to 1) delete the resource, then 2) add the resource by the new name. The operation is atomic, so if it fails the old resource will still be there.

Parameters:

currentPath - current path of the resource

newName - the name of the new resource

Returns:

the actual path for the new resource

RegistryException - if something went wrong

copy

String copy(String sourcePath,
            String targetPath)
