- org.apache.log4j.AppenderSkeleton
- - org.apache.log4j.nt.NTEventLogAppender

All Implemented Interfaces:

Appender, OptionHandler
```
public class NTEventLogAppender
extends AppenderSkeleton
```
Append to the NT event log system.
WARNING This appender can only be installed and used on a Windows system.
Do not forget to place NTEventLogAppender.dll, NTEventLogAppender.amd64.dll, NTEventLogAppender.ia64.dll or NTEventLogAppender.x86.dll as appropriate in a directory that is on the PATH of the Windows system. Otherwise, you will get a java.lang.UnsatisfiedLinkError.

```
public void close()
```
    Description copied from interface: Appender
    
    Release any resources allocated within the appender such as file handles, network connections, etc.
    It is a programming error to append to a closed appender.
  - activateOptions
```
public void activateOptions()
```
    Description copied from class: AppenderSkeleton
    
    Derived appenders should override this method if option structure requires it.
    
    Specified by:
    
    activateOptions in interface OptionHandler
    
    Overrides:
    
    activateOptions in class AppenderSkeleton
  - append
```
public void append(LoggingEvent event)
```
    Description copied from class: AppenderSkeleton
    
    Subclasses of AppenderSkeleton should implement this method to perform actual logging. See also AppenderSkeleton.doAppend method.
    
    Specified by:
    
    append in class AppenderSkeleton
  - finalize
```
public void finalize()
```
    Description copied from class: AppenderSkeleton
    
    Finalize this appender by calling the derived class' close method.

    finalize in class AppenderSkeleton
  - setSource
```
public void setSource(java.lang.String source)
```
    The Source option which names the source of the event. The current value of this constant is Source.
  - getSource
```
