    Return the name of this Logger instance.
    
    Specified by:
    
    getName in interface Logger
    
    Returns:
    name of this logger instance
  - isTraceEnabled
```
public boolean isTraceEnabled()
```
    Description copied from interface: Logger
    
    Is the logger instance enabled for the TRACE level?
    
    Specified by:
    
    isTraceEnabled in interface Logger
    
    Returns:
    True if this Logger is enabled for the TRACE level, false otherwise.
  - trace
```
public void trace(String msg)
```
    Description copied from interface: Logger
    
    Log a message at the TRACE level.
    
    Specified by:
    
    trace in interface Logger
    
    Parameters:
    msg - the message string to be logged
  - trace
```
public void trace(String format,
         Object arg)
```
    Description copied from interface: Logger
    
    Log a message at the TRACE level according to the specified format and argument.
    
    This form avoids superfluous object creation when the logger is disabled for the TRACE level.
    
    Specified by:
    
    trace in interface Logger
    
    Parameters:
    format - the format string
    arg - the argument
  - trace
```
public void trace(String format,
         Object arg1,
         Object arg2)
```
    Description copied from interface: Logger
    
    Log a message at the TRACE level according to the specified format and arguments.
    
    This form avoids superfluous object creation when the logger is disabled for the TRACE level.
    
    Specified by:
    
    trace in interface Logger
    
    Parameters:
    format - the format string

public void info(Marker marker,

        Throwable t)
```
    Description copied from interface: Logger
    
    This method is similar to Logger.info(String, Throwable) method except that the marker data is also taken into consideration.
    
    Specified by:
    
    info in interface Logger
    
    Parameters:
    marker - the marker data for this log statement
    msg - the message accompanying the exception
    t - the exception (throwable) to log
  - isWarnEnabled
```
public boolean isWarnEnabled()
```
    Description copied from interface: Logger
    
    Is the logger instance enabled for the WARN level?
    
    Specified by:
    
    isWarnEnabled in interface Logger
    
    Returns:
    True if this Logger is enabled for the WARN level, false otherwise.
  - warn
```
public void warn(String msg)
```
    Description copied from interface: Logger
    
    Log a message at the WARN level.
    
    Specified by:
    
    warn in interface Logger
    
    Parameters:
    msg - the message string to be logged
  - warn
```
public void warn(String format,
        Object arg)
```
    Description copied from interface: Logger
    
    Log a message at the WARN level according to the specified format and argument.
    
    This form avoids superfluous object creation when the logger is disabled for the WARN level.
    
    Specified by:
    
    warn in interface Logger
    
    Parameters:
    format - the format string
    arg - the argument
  - warn
```
public void warn(String format,
        Object arg1,
        Object arg2)
```
    Description copied from interface: Logger
    
    Log a message at the WARN level according to the specified format and arguments.
    
    This form avoids superfluous object creation when the logger is disabled for the WARN level.
    
    Specified by:
    
    warn in interface Logger
    
    Parameters:
    format - the format string
    arg1 - the first argument
    arg2 - the second argument
  - warn
```
public void warn(String format,
        Object... arguments)
```
    Description copied from interface: Logger
    
    Log a message at the WARN level according to the specified format and arguments.
    
    This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for WARN. The variants taking one and two arguments exist solely in order to avoid this hidden cost.
    
    Specified by:
    
    warn in interface Logger
    
    Parameters:
    format - the format string
    arguments - a list of 3 or more arguments
  - warn
```

    Parameters:
    msg - the message accompanying the exception
    t - the exception (throwable) to log
