GeneralizingSAstVisitor<T> class

A visitor that adds category-level fallback methods between specific visit methods and visitNode.

The delegation chain for a concrete node mirrors the analyzer's type hierarchy. For example:

visitSimpleIdentifier → visitIdentifier → visitExpression
    → visitCollectionElement → visitNode

Override a category method to handle all nodes of that kind in one place.
