		### Traversing the CST

		See relevant [Chevrotain documentation on CST Traversal](http://sap.github.io/chevrotain/docs/guide/concrete_syntax_tree.html#traversing).

		```javascript
		const {
		BaseJavaCstVisitor,
		BaseJavaCstVisitorWithDefaults
		} = require("java-parser");

		// Use "BaseJavaCstVisitor" if you need to implement all the visitor methods yourself.
		class LambdaArrowsPositionCollector extends BaseJavaCstVisitorWithDefaults {

		super();
		this.result = [];
		this.validateVisitor();
		}

		lambdaExpression(ctx) {
		// Collects all the starting offsets of lambda arrows in lambdas with short (no parenthesis)
		// single argument lists: e.g:
		// - n -> n*n (will be collected)
		// - (n) -> n*n (not collected)
		if (ctx.lambdaParameters.children.Identifier.length > 0) {
		this.result.push(ctx.Arrow[0].startOffset);
		}
		}
		}

		// The CST result from the previous code snippet
		lambdaArrowsCollector.visit(cst);
		lambdaArrowsCollector.result.forEach(arrowOffset => {
