```
static Logger instance()
```
    Service access API
    
    Returns:
    
    Logger instance with default name and Level
  - atDebug
```
Logger atDebug()
```
    Service access API
    
    Returns:
    
    Logger instance with Level.DEBUG severity level
  - atError
```
Logger atError()
```
    Service access API
    
    Returns:
    
    Logger instance with Level.ERROR severity level
  - atInfo
```
Logger atInfo()
```
    Service access API
    
    Returns:
    
    Logger instance with Level.INFO severity level
  - atTrace
```
Logger atTrace()
```
    Service access API
    
    Returns:
    
    Logger instance with Level.TRACE severity level
  - atWarn
```
Logger atWarn()
```
    Service access API
    
    Returns:
    
    Logger instance with Level.WARN severity level
  - getLevel
```
Level getLevel()
```
    Service interface API
    
    Returns:
    
    Severity level of the logger instance
  - isEnabled
```
boolean isEnabled()
```
    Service interface API
    
    Returns:
    
    true if the active logging of this instance enabled per configuration, false otherwise
  - log
```
void log(Object message)
```
    Service interface API
    
    Parameters:
    
    message - to be logged. If the actual type is Supplier, the result of Supplier.get(), instead of the message itself, should be used to construct the final log message.
  - log
```
void log(String message,
         Object... args)
```
    Service interface API
    
    Parameters:
    
    message - to be logged
    
    args - the arguments to replace the placeholders in the message. If any of the argument's actual type is Supplier, the result of Supplier.get(), instead of the argument itself, should be used to construct the final log message.
  - log
```
void log(Throwable t)
```
    Service interface API
    
    Parameters:
    
    t - the Throwable to be logged
  - log
```
void log(Throwable t,
         Object message)
```
    Service interface API
    
    Parameters:
    
    t - the Throwable to be logged
    
    message - the message to be logged. If the actual type is Supplier, the result of Supplier.get(), instead of the message itself, should be used to construct the final log message.
  - log
```
void log(Throwable t,
         String message,
         Object... args)
```
    Service interface API
    
    Parameters:
    
    t - the Throwable to be logged
    
    message - the message to be logged
    
    args - the arguments to replace the placeholders in the message. If any of argument's actual type is Supplier, the result of Supplier.get(), instead of the argument itself, should be used to construct the final log message.
