```
  - ALL_INTEGER
```
public static final Integer 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.
  - levelInt
```
public final int levelInt
```
  - levelStr
```
public final String levelStr
```
- Method Detail
  - 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:
    
    levelInt - An integer value representing a level as defined in LocationAwareLogger
    
    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:
    
    1.0.1
