is selected if no other implementation class name can be discovered. Its primary purpose is to create (as necessary) and return Log instances in response to calls to the getInstance() method. The default implementation uses the following rules: At most one Log instance of the same name will be created. Subsequent getInstance() calls to the same LogFactory instance, with the same name or Class parameter, will return the same Log instance. When a new Log instance must be created, the default LogFactory...
