public final class LogManager extends Object
By default, all context(s) are logged by the LogManager. The messages that the LogManager actually records and sends to the destinations can be controlled using two different and orthogonal parameters. The first is a message level that filters messages based upon detail, and the second is a message context that filters messages based upon origin. The LogManager tracks only those context(s) that should NOT be logged. Only if a message (which also is defined with these two parameters) passes both filters will it be sent to the destinations.
Each message is submitted with one of the following levels (determined by the particular method used to submit the message), sorted from the least detailed to the greatest:
The context for a message is any application-specified String. Again, only those message contexts that match those in the LogManager's configuration will be sent to the destinations.
