- Method Detail
  - isDebugEnabled
```
boolean isDebugEnabled()
```
    Is debug logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.
    
    Returns:
    true if debug is enabled in the underlying logger.
  - isErrorEnabled
```
boolean isErrorEnabled()
```
    Is error logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than error.
    
    Returns:
    true if error is enabled in the underlying logger.
  - isFatalEnabled
```
boolean isFatalEnabled()
```
    Is fatal logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than fatal.
    
    Returns:
    true if fatal is enabled in the underlying logger.
  - isInfoEnabled
```
boolean isInfoEnabled()
```
    Is info logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than info.
    
    Returns:
    true if info is enabled in the underlying logger.
  - isTraceEnabled
```
boolean isTraceEnabled()
```
    Is trace logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than trace.
    
    Returns:
    true if trace is enabled in the underlying logger.
  - isWarnEnabled
```
boolean isWarnEnabled()
```
    Is warn logging currently enabled?
    
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than warn.
    
    Returns:
    true if warn is enabled in the underlying logger.
