public class Level
extends Priority
implements Serializable

Defines the minimum set of levels recognized by the system, that is OFF, FATAL, ERROR, WARN, INFO, DEBUG, TRACE, and ALL.

The Level class may be subclassed to define a larger level set.

Field Summary
static Level ALL
          The ALL has the lowest possible rank and is intended to turn on all logging.
static Level DEBUG
          The DEBUG Level designates fine-grained informational events that are most useful to debug an application.
static Level ERROR
          The ERROR level designates error events that might still allow the application to continue running.
static Level FATAL
          The FATAL level designates very severe error events that will presumably lead the application to abort.
static Level INFO
          The INFO level designates informational messages that highlight the progress of the application at coarse-grained level.
static Level OFF
          The OFF has the highest possible rank and is intended to turn off logging.
static Level TRACE
          The TRACE Level designates finer-grained informational events than the DEBUG
static int TRACE_INT
          TRACE level integer value.
static Level WARN
          The WARN level designates potentially harmful situations.

Constructor Detail

Level

protected Level(int level,
                String levelStr,
                int syslogEquivalent)
Instantiate a level object.
Parameters:
level - The integer level value
levelStr - The level name
syslogEquivalent - The UNIX SystLog level equivalent
Method Detail

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.
Parameters:
sArg - The level name
Returns:
The matching Level object

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.
Parameters:
val - The level integer value
Returns:
The matching Level object

equals

public boolean equals(Object o)
Two Levels (formerly Priorities) are equal if their level integer value fields are equal. If the argument is not a Level, this method returns False.
Overrides:
equals in class Priority
Parameters:
o - The other Level
Returns:
boolean True if equals
Since:
1.2

hashCode

public int hashCode()
The hashCode of a Level (i.e. Priority) is its level field.
Overrides:
hashCode in class Object
Returns:
The integer level value

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.
Parameters:
val - The integer value
defaultLevel - The Level to return if no match is found
Returns:
The matching Level

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 defaultLevel.
Parameters:
sArg - The Level name
defaultLevel - Level to return if no match is found
Returns:
The matching Level
