SourceBuffer (java-gnome 4.1.3 API Documentation)

Object
- org.freedesktop.bindings.Pointer

      - org.gnome.sourceview.SourceBuffer

```
public class SourceBuffer
extends TextBuffer
```
SourceBuffer is the model used in a SourceView. It extends GTK's TextBuffer and adds features typical for text editors. SourceBuffer contains the actual text that is displayed in the view and allows its manipulation.
Usage
The following example shows how a SourceBuffer is created and its initial content is set:
```
 TextTagTable table;
 SourceBuffer buffer;
 ...
 
 table = new TextTagTable();
 buffer = new SourceBuffer();
 buffer.setText("Insert text here...");
 
```
The language used for syntax highlighting has to be obtained from the LanguageManager:
```
 manager = LanguageManager.getDefault();
 language = manager.getLanguage("java");
 buffer.setLanguage(language);
 
```

4.0.12
