Enum Class LogLevel

java.lang.Object

java.lang.Enum<LogLevel>

provided.logger.LogLevel

All Implemented Interfaces:

Serializable, Comparable<LogLevel>, Constable

public enum LogLevel
extends Enum<LogLevel>

Enumeration values for classifying log messages. Note that all enums (java.lang.Enum) derivatives implement the Comparable interface, so to compare them, use their inherited compareTo() method. The relative "size" of the log levels is defined by their order of declaration with the first declaration having the "smallest" value.
