constructor

new AbstractVisitor<N extends VisitorNode<N>>(
factory: Factory<N, FactoryNodeClass<N>>,
): AbstractVisitor<N>
Create the node handler map by looking for methods with the correct names based on the node kinds available from the factory.
Type Parameters
- N extends VisitorNode<N>
Parameters
- factory: Factory<N, FactoryNodeClass<N>>
