Class
    Foam::IOOutputFilter

Description
    IOdictionary wrapper around OutputFilter to allow them to read from
    their associated dictionaries.

Note
    The IOobject or the objectRegistry will normally have to be
    derived from a fvMesh for a subsequent cast (within OutputFilter)
    to work correctly.
