virtual FDO_API_COMMON FdoBoolean FdoIoFileStream::HasContext | ( |  | ) | `[virtual]`
returns whether the stream has any positional context. Streams without context can only be read and written in a forward-only manner. These streams do not allow position and length changes. Returns: Returns true if the stream has context. Returns false if it does not. When a stream does not have context, the SetLength(), Skip() and Reset() functions are not supported. Reimplemented from FdoIoStream.
