LookaheadIterator (ch.usi.si.seart:java-tree-sitter 1.12.0 API)

java.lang.Object
- ch.usi.si.seart.treesitter.LookaheadIterator

All Implemented Interfaces:

AutoCloseable, Iterator<Symbol>
```
public class LookaheadIterator
extends Object
implements Iterator<Symbol>
```
Specialized iterator that can be used to generate suggestions and improve syntax error diagnostics. To get symbols valid in an ERROR node, use the lookahead iterator on its first leaf node state. For MISSING nodes, a lookahead iterator created on the previous non-extra leaf node may be appropriate.

Since:

1.12.0
