WhitespaceRule (jEdit API Documentation)

java.lang.Object
- org.gjt.sp.jedit.indent.WhitespaceRule

All Implemented Interfaces:

IndentRule
```
public class WhitespaceRule
extends java.lang.Object
implements IndentRule
```
Whitespace rule. This rule cancels all indent actions in the following case:
- The previous line is all whitespace
- The current line is not empty
The result is that this rule won't allow the indentation to be increased, only decreased (by rules triggered by unindentThisLine). If the requirements above do not apply, this rule does nothing.
Since:

jEdit 4.3pre10
