Defines the base class for Receiver plugins.
Just as Appenders send logging events outside of the log4j environment (to files, to smtp, to sockets, etc), Receivers bring logging events inside the log4j environment.
Receivers are meant to support the receiving of remote logging events from another process.
Receivers can also be used to "import" log messages from other logging packages into the log4j environment.
Receivers can be configured to post events to a given LoggerRepository.
Subclasses of Receiver must implement the isActive(), activateOptions(), and shutdown() methods. The doPost() method is provided to standardize the "import" of remote events into the repository.
