### EXPORTS

`next_one(Iterator) -> Return`

Types:

`Iterator = #objref`
`Return = {boolean(), #'CosFileTransfer_FileWrapper'{the_file = File file_type = Type}}`
`File = #objref`
`Type = nfile | ndirectory`

This opertion returns true if a `FileWrapper` exists at the current position and the out parameter contains a valid `File` reference. If false is returned the out parameter is a non-valid `FileWrapper`.

`next_n(Iterator, Max) -> Return`

Types:

`Iterator = #objref`
`Max = unsigned long()`
`Return = {boolean(), FileList}`
`FileList = [#'CosFileTransfer_FileWrapper'{the_file = File file_type = Type}]`
`File = #objref`
`Type = nfile | ndirectory`

This operation returns true if the requested number of `FileWrappers` can be delivered and there are additional `FileWrappers`. If false is returned a list, of length `Max` or less, containing the last valid `FileWrappers` associated with the target object.

`destroy(Iterator) -> ok`

Types:

`Iterator = #objref`

This operation terminates the target object.
