LoggerBase (Payara Project 5.193.1 API)

java.lang.Object
- org.apache.catalina.logger.LoggerBase

All Implemented Interfaces:

Lifecycle, Logger

Direct Known Subclasses:

FileLogger, SystemErrLogger, SystemOutLogger
```
public class LoggerBase
extends Object
implements Lifecycle, Logger
```
Convenience base class for Logger implementations. The only method that must be implemented is log(String msg), plus any property setting and lifecycle methods required for configuration.

```
public void log(Exception exception,

  - start
```
public void start()
           throws LifecycleException

    Specified by:
    
    start in interface Lifecycle
    
    Throws:
    
    LifecycleException - if this component detects a fatal error that prevents this component from being used
  - stop
```
public void stop()
          throws LifecycleException
