The derived classes should overrid this method and return true or false whether it was able to cast the past in view to a view that it can interface to. So if you are a projective view you might cast to an ossimProjection. The ownsTheView specifies whether or not it owns the passed in view pointer. This will specifiy whether or not the derived classes need to re-allocate the pointer or just delete its old pointer and set it to the passed in pointer.
