NodeViewMode (Apache Velocity 1.7 API)

java.lang.Object
- org.apache.velocity.runtime.visitor.BaseVisitor
- - org.apache.velocity.runtime.visitor.NodeViewMode

All Implemented Interfaces:

ParserVisitor
```
public class NodeViewMode
extends BaseVisitor
```
This class is simply a visitor implementation that traverses the AST, produced by the Velocity parsing process, and creates a visual structure of the AST. This is primarily used for debugging, but it useful for documentation as well.
