DescendantsTreeIterator (MPS.Core (JetBrains MPS 2019.1.0))

java.lang.Object
- org.jetbrains.mps.util.DescendantsTreeIterator

All Implemented Interfaces:

Iterator<SNode>, TreeIterator<SNode>
```
public final class DescendantsTreeIterator
extends Object
implements TreeIterator<SNode>
```
Iterator for a SNode sub-tree.
Pre-order traversal, parent node is visited prior to any of its children, no sibling is visited prior to all children of its predecessor.
Iterator gives control over sub-tree iteration with skipChildren() method to completely skip processing of a sub-tree rooted at latest node returned from next().
At the moment, iterator doesn't support deletions.
