Enum Class LogLevel

java.lang.Object
java.lang.Enum<LogLevel>
org.daiitech.naftah.playground.utils.logging.LogLevel
All Implemented Interfaces:
Serializable, Comparable<LogLevel>, Constable
public enum LogLevel extends Enum<LogLevel>
Defines the logging levels supported by the playground logging system.

Levels are ordered by severity, from ERROR (highest severity) to TRACE (most verbose). Each level is associated with a numeric rank used to determine whether a log message should be emitted.

For example, a logger configured with INFO will allow ERROR, WARN, and INFO messages, but will suppress DEBUG and TRACE messages.

    • rank

      final int rank
      Internal rank used to compare logging levels.

  • Constructor Details

    • LogLevel

      private LogLevel(int rank)
      Creates a logging level with the specified rank.
      Parameters:
      rank - the numeric rank associated with the level

  • Method Details

    • values

      public static LogLevel[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static LogLevel valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • allows

      public boolean allows(LogLevel other)
      Determines whether this logging level permits messages of the specified level.

      A level allows itself and all levels with higher severity.

      Parameters:
      other - the message level to evaluate
      Returns:
      true if messages at other level should be logged; false otherwise

    • fromString

      public static LogLevel fromString(String s)
      Converts a string representation into a LogLevel.

      The comparison is case-insensitive. If the supplied value is null, empty, or does not correspond to a valid logging level, INFO is returned.

      Parameters:
      s - the string representation of the log level
      Returns:
      the corresponding LogLevel, or INFO if the input is invalid
