virtual

Reads an object from the input stream.

Overloads the member function defined for the IlvManagerInputFile class. It adds information specific to each object in its description block. This information includes the layer index as well as the type of the object (node, link, or other type of object). The method is internally called by the IlvManagerInputFile::readAll method and is not to be called directly by the programmer.

Returns
The graphic object read from the input stream.

Reimplemented from IlvManagerInputFile.
