Objects

Objects in Coldmud have four characteristics: a database reference (called a dbref) which identifies the object, a list of parent dbrefs which determine what default behavior the object inherits, variables which store information, and methods which determine how the object responds to messages. Objects refer to each other using dbrefs, and interact with each other by sending messages. The objects which a Coldmud server has to work with are known collectively as the object database.

Coldmud gives special status to two objects, the system object and the root object. The system object is allowed to call administrative functions and receives startup and heartbeat messages from the server. The root object is the only object without parents, and is thus an ancestor of every object.
