LoggerWrapper (MMBase 1.9-SNAPSHOT

java.lang.Object
- org.mmbase.util.logging.LoggerWrapper

All Implemented Interfaces:

Logger
```
public class LoggerWrapper
extends Object
implements Logger
```
Wraps a logger instance. This can be used for static logger instances which might be instatatied before logging itself is configured. After configurating logging, all static 'wrappers' can then be called to wrap another logger instance.

MMBase-1.7

    Logs the message m with trace priority. For detailled debugging.

  - debug
```
public final void debug(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with debug priority. Everything a non-developer never wants to see, but you do, to * keep track of what is happening. There can be a lot of them in the code, so it is important that you well protect them with `isDebugEnabled's, to minimize overhead.

  - service
```
public final void service(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with service priority. An interested system administrator might want to see these things. For examples all queries to the database could be logged with `service' priority. Or if a image is calculated, that could be logged as a `service'. One would get a fairly good idea what MMBase is doing if `service' is switched on.

  - info
```
public final void info(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with info priority. As `service', but focussed on things system administrators are usually most interested in, like authorisation issues. For example changes on the database could be logged, such that one can see in the logs what happened.
    
    Specified by:

public final void info(Object m,

  - warn
```
public final void warn(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with warn priority. Something strange happened, but it is not necessarily an error.
    
    Specified by:
    
    warn in interface Logger
  - warn
```
public final void warn(Object m,

  - error
```
public final void error(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with error priority. Something is definitely wrong. An inconsistency was detected. It might be unpredictable what will happen.
    
    Specified by:
    
    error in interface Logger
  - error
```
public final void error(Object m,

  - fatal
```
public final void fatal(Object m)
```
    Description copied from interface: Logger
    
    Logs the message m with fatal priority. The progam could not function any more. Normally, you would throw an exception, which then will be logged with fatal priority. I've made an arangement in `Logger' that logs uncatched exceptions with fatal priority, but nevertheless it's better to always catch all exceptions in a more regulated way.
    
    Specified by:

  - fatal

public final void fatal(Object m,

public final boolean isTraceEnabled()
```
    Description copied from interface: Logger
    
    Returns true if for this category (Logger), a call to trace would do something.

  - isDebugEnabled
```
public final boolean isDebugEnabled()
```
    Description copied from interface: Logger

    Description copied from interface: Logger

  - setLevel
```
public final void setLevel(Level p)
```
    Description copied from interface: Logger
    
    If you want to override the level in the configuration file fixed for this category, you can do it with this method. This could be usefull for example to switch on all debug logging when something has gone wrong.
    
    Specified by:
    
    setLevel in interface Logger
    
    Parameters:
    
    p - The level of the priority. One of the constants Level.TRACE, Level.DEBUG, Level.SERVICE, Level.INFO, Level.WARN, Level.ERROR or Level.FATAL.
