All Known Implementing Classes:

ProgressHelper, TextIndexer
```
public interface MonitoredAlgorithm
```
A MonitoredAlgorithm is an algorithm that can report on its progress as it completes. It supports a single listener (although that listener can chain to other listeners if needed) that will be notified as the algorithm progresses.

ProgressListener setProgressListener(ProgressListener li)
```
    Sets the progress listener that will listen for progress on this algorithm, replacing the existing listener (if any). A listener should only be set before the algorithm begins executing, not while it is already in progress.
    
    Parameters:
    
    li - the listener to set (may be null)
    
    Returns:
    
    the previous listener, or null
