public abstract class AbstractLogModel
extends Object
implements LogModel

A base implementation of the LogModel interface.

This class implements some of the basic functionality of the LogModel interface. You don't use this class directly, instead, you use one of its derived classes (such as SystemLogModel or DefaultLogModel). Alternatively, you can use this as a base class to create your own LogModel.
