PVideoControlInfo::P_DECLARE_STREAMABLE_ENUM | ( | Types | , |

) |
|
virtual |
Output the contents of the object to the stream.
The exact output is dependent on the exact semantics of the descendent class. This is primarily used by the standard operator<<
function.
The default behaviour is to print the class name.
Reimplemented from PObject.
