ActiveLineRangeListener (rsyntaxtextarea 2.5.8 API)

All Superinterfaces:

EventListener
```
public interface ActiveLineRangeListener
extends EventListener
```
Listens for "active line range" events from an RSyntaxTextArea. If a text area contains some semantic knowledge of the programming language being edited, it may broadcast ActiveLineRangeEvents whenever the caret moves into a new "block" of code. Listeners can listen for these events and respond accordingly.
See the RSTALanguageSupport project at http://fifesoft.com for some LanguageSupport implementations that may broadcast these events. Note that if an RSTA/LanguageSupport does not support broadcasting these events, the listener will simply never receive any notifications.
