    from a frame filter object.  This is a fail free function as it is
    used in sorting and filtering.  If a badly implemented frame
    filter does not implement the priority attribute, return zero
    (otherwise sorting/filtering will fail and prevent other frame
    filters from executing).

    Arguments:
        filter_item: An object conforming to the frame filter
                     interface.

    Returns:
        The priority of the frame filter from the "priority"
        attribute, or zero.

r6cCst|||d�S)a/Helper function that will execute the chain of frame filters.
    Each filter is executed in priority order.  After the execution
    completes, slice the iterator to frame_low - frame_high range.  An
    iterator is always returned.  The iterator will always yield
    frame decorator objects, but note that these decorators have
    slightly different semantics from the ordinary ones: they will
    always return a fully-qualified 'filename' (if possible) and will
    never substitute the objfile name.

    Arguments:
        frame: The initial frame.

        frame_low: The low range of the slice, counting from 0.  If
        this is a negative integer then it indicates a backward slice
        (ie bt -4) which counts backward from the last frame in the
        backtrace.

        frame_high: The high range of the slice, inclusive.  If this
        is -1 then it indicates all frames until the end of the stack
        from frame_low.

    Returns:
        frame_iterator: The sliced iterator after all frame
        filters have had a chance to execute.

rr3�sr3cCst|||d�S)aDInternal function called from GDB that will execute the chain
    of frame filters.  Each filter is executed in priority order.
    After the execution completes, slice the iterator to frame_low -
    frame_high range.

    Arguments:
        frame: The initial frame.

        frame_low: The low range of the slice, counting from 0.  If
        this is a negative integer then it indicates a backward slice

        is -1 then it indicates all frames until the end of the stack
        from frame_low.

    Returns:
        frame_iterator: The sliced iterator after all frame
        filters have had a chance to execute, or None if no frame
        filters are registered.
