Classes & Methods

Extracting class declarations and expressions, classifying method kinds (regular, getters, setters, private), and maintaining parent class pointers.

Method Kinds & Classification

When extracting class methods, the extractor classifies the method into a specific MethodKind:

Method Kind	AST Node / Condition	Example Code
"method"	ClassMethod where kind === 'method'	class A { run() {} }
"get"	ClassMethod where kind === 'get'	class A { get total() { return 10; } }
"set"	ClassMethod where kind === 'set'	class A { set total(v) {} }
"private"	ClassPrivateMethod (PrivateName #key)	class A { #executeInternal() {} }

Private Method Extraction

ECMAScript private methods (#privateMethod()) use PrivateName AST nodes rather than standard Identifier nodes. The extractor unwraps the identifier name safely:

if (path.isClassPrivateMethod()) {
    const key = path.node.key;
    if (key.type === "PrivateName") {
        return key.id.name; // Extracts 'executeInternal' from '#executeInternal'
    }
}

private getMethodKind(path: NodePath<ClassMethod | ClassPrivateMethod | ObjectMethod>): MethodKind {
    if (path.isClassPrivateMethod()) return "private";
    return path.node.kind === "get" || path.node.kind === "set" ? path.node.kind : "method";
}

Parent Class Linking

Because ClassDeclaration is a container visitor, the class symbol is placed on symbolStack. When any ClassMethod is visited, its parentSymbolId is automatically set to the class ID.
