All Implemented Interfaces:: java.lang.Runnable, ErrorAware, LogTarget, Closeable

public class AsyncLogTarget
extends AbstractWrappingTarget
implements java.lang.Runnable

An asynchronous LogTarget that sends entries on in another thread. It is the responsibility of the user of this class to start the thread etc.

 LogTarget mySlowTarget = ...;
 AsyncLogTarget asyncTarget = new AsyncLogTarget( mySlowTarget );
 Thread thread = new Thread( asyncTarget );
 thread.setPriority( Thread.MIN_PRIORITY );
 thread.start();

 logger.setLogTargets( new LogTarget[] { asyncTarget } );

  - AsyncLogTarget
```
public AsyncLogTarget(LogTarget logTarget)
```
    Creation of a new async log target.
    
    Parameters:
    
    logTarget - the underlying target
  - AsyncLogTarget
```
public AsyncLogTarget(LogTarget logTarget,
                      int queueSize)
```
    Creation of a new async log target.
    
    Parameters:
    
    logTarget - the underlying target
    
    queueSize - the queue size
  - AsyncLogTarget
```
public AsyncLogTarget(LogTarget logTarget,
                      boolean closeTarget)
```
    Creation of a new async log target.
    
    Parameters:
    
    logTarget - the underlying target
    
    closeTarget - close the underlying target when this target is closed. This flag has no effect unless the logTarget implements Closeable.
  - AsyncLogTarget
```
public AsyncLogTarget(LogTarget logTarget,
                      int queueSize,
                      boolean closeTarget)
```
    Creation of a new async log target.
    
    Parameters:
    
    logTarget - the underlying target
    
    queueSize - the queue size
    
    closeTarget - close the underlying target when this target is closed. This flag has no effect unless the logTarget implements Closeable.
