PrettyTree (yangtools-docs 8.0.7 API)

java.lang.Object
- org.opendaylight.yangtools.concepts.PrettyTree

All Implemented Interfaces:

Supplier<String>

Direct Known Subclasses:

NormalizedNodePrettyTree
```
@Beta
public abstract class PrettyTree
extends Object
implements Supplier<String>
```
A capture of a tree-like construct, which can be formatted into a pretty-printed tree. The string can be acquired via get().
This concept is purposefully designed as an abstract class which defers its toString() to get(), as it allows convenient and light-weight use with logging:
```
   
     PrettyTreeAware treeLike;
     LOG.debug("Tree is {}", treeLike.prettyTree());
   
 
```
