class Frame(object):
    """`Frame` object within a `Page`, holding onto a `Dataset` and a `Plot`.

    Parameters:
        uid (`integer <int>`, optional): This must be a *valid* unique ID
            number pointing internally to a Frame object or `None`. A new
            `Frame` is created if set to `None`. (default: `None`)
        page (`Page`, optional): The destination `Page` of this newly
            created `Frame`. If `None`, the currently active `Page` is used.
            (default: `None`)

    Warning:
        Though it is possible to create a `Frame` object using the
        constructor, it is usually sufficient to obtain a frame through
        `tecplot.active_frame()` or `Page.frame()`. One can also create a
        `Frame` using a `Page` handle with `Page.add_frame()`.

    The concept of the `Frame` is central to understanding the
    |Tecplot Engine|. The `Frame` is what connects a `Dataset` to a `Plot`
    handle from which one manipulates the desired image as well as accessing
    the attached data::

        >>> import tecplot
        >>> frame = tecplot.active_frame()
        >>> frame
        Frame(uid=11, Page(uid=1))
