    • ALL_INTEGER

    • OFF

      public static final Level OFF
      The OFF is used to turn off logging. It is intended to be used for logging system configuration. Warning: it should never be passed as an argument to logger methods in a regular log statement.

    • ERROR

      public static final Level ERROR
      The ERROR level designates error events which may or not be fatal to the application.

    • WARN

      public static final Level WARN
      The WARN level designates potentially harmful situations.

    • INFO

      public static final Level INFO
      The INFO level designates informational messages highlighting overall progress of the application.

    • DEBUG

      public static final Level DEBUG
      The DEBUG level designates informational events of lower importance.

    • TRACE

      public static final Level TRACE
      The TRACE level designates informational events of very low importance.

    • ALL

      public static final Level ALL
      Deprecated.
      with no replacement

      The ALL is used to turn on all logging. The ALL level is vestigial from log4j 1.x.

      In logback, where the Level class is final, logging can be turned on for all levels by setting a logger's level to TRACE.

      Thus, the ALL level is marked as deprecated.

  • Method Details

    • toString

      public String toString()
      Returns the string representation of this Level.
      Overrides:
      toString in class Object

    • toInt

      public int toInt()
      Returns the integer representation of this Level.

    • convertAnSLF4JLevel

      public static Level convertAnSLF4JLevel(org.slf4j.event.Level slf4jLevel)

    • toInteger

      public Integer toInteger()
      Convert a Level to an Integer object.
      Returns:
      This level's Integer mapping.

    • isGreaterOrEqual

      public boolean isGreaterOrEqual(Level r)
      Returns true if this Level has a higher or equal Level than the Level passed as argument, false otherwise.

    • toLevel

      public static Level toLevel(String sArg)
      Convert the string passed as argument to a Level. If the conversion fails, then this method returns DEBUG.

    • valueOf

      public static Level valueOf(String sArg)
      This method exists in order to comply with Joran's valueOf convention.
      Parameters:
      sArg -
      Returns:

    • toLevel

      public static Level toLevel(int val)
      Convert an integer passed as argument to a Level. If the conversion fails, then this method returns DEBUG.

    • toLevel

      public static Level toLevel(int val, Level defaultLevel)
      Convert an integer passed as argument to a Level. If the conversion fails, then this method returns the specified default.

    • toLevel

      public static Level toLevel(String sArg, Level defaultLevel)
      Convert the string passed as argument to a Level. If the conversion fails, then this method returns the value of defaultLevel.

    • fromLocationAwareLoggerInteger

      public static Level fromLocationAwareLoggerInteger(int levelInt)
      Convert one of the integer values defined in LocationAwareLogger interface to an instance of this class, i.e. a Level.
      Parameters:

      Returns:
      an instance of this class, i.e. a Level.
      Since:
      1.0.1

    • toLocationAwareLoggerInteger

      public static int toLocationAwareLoggerInteger(Level level)
      Convert this level instance to an integer value defined in the LocationAwareLogger interface.
      Parameters:
      level - The level to convert to LocationAwareLogger integer
      Returns:
      int An integer corresponding to this level as defined in LocationAwareLogger
      Since:
