InputStreamLineListener (Norconex Commons Lang 2.1.0 API)

java.lang.Object
- com.norconex.commons.lang.io.InputStreamLineListener

All Implemented Interfaces:

IInputStreamListener
```
public abstract class InputStreamLineListener
extends Object
implements IInputStreamListener
```
Listener that is being notified every time a line is processed from a given stream. Not thread-safe. Use a new instance for each thread or at a minimum, make sure to give a unique type argument to each InputStreamConsumer to prevent lines content being mixed up.
