  - isFatalEnabled
```
public boolean isFatalEnabled()
```
    Description copied from interface: Log
    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.
    Specified by:
    isFatalEnabled in interface Log
    Returns:
    true if fatal is enabled in the underlying logger.
  - isErrorEnabled
```
public boolean isErrorEnabled()
```
    Description copied from interface: Log

    Specified by:
    isErrorEnabled in interface Log
    Returns:
    true if error is enabled in the underlying logger.
  - isWarnEnabled
```
public boolean isWarnEnabled()
```
    Description copied from interface: Log
    Is warn logging currently enabled?

    Specified by:
    isWarnEnabled in interface Log
    Returns:
    true if warn is enabled in the underlying logger.
  - isInfoEnabled
```
public boolean isInfoEnabled()
```
    Description copied from interface: Log
    Is info logging currently enabled?

    Returns:
    true if info is enabled in the underlying logger.
  - isDebugEnabled
```
public boolean isDebugEnabled()
```
    Description copied from interface: Log
    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.
    Specified by:

    Returns:
    true if debug is enabled in the underlying logger.
  - isTraceEnabled
```
public boolean isTraceEnabled()
```
    Description copied from interface: Log

    Specified by:
    isTraceEnabled in interface Log
    Returns:
    true if trace is enabled in the underlying logger.
