Q:

JavaPoet check if TypeName is instance of List

In JavaPoet I can get a TypeName from every Class like this as an example for the List class.
TypeName TYPE_LIST = ClassName.get(List.class);

But how can I check now if a given TypeName is an instance of a List?  Let's say I have a method which returns a List<String>. I can get the return type by using:
TypeName returnTyoe = TypeName.get(method.getReturnType());

How can I check if tis method reurns a List? I do not care if it is a List<String> I only want to know if it is at least a List and ignore the generic parameter completely.

A:

Found an even better way. For everyone also struggling with that use below code:
TypeName TYPE_LIST = ClassName.get(List.class);
boolean isList = isFromType(type, TYPE_LIST)

public static boolean isFromType(TypeName requestType, TypeName expectedType) {
    if(requestType instanceof ParameterizedTypeName) {
        TypeName typeName = ((ParameterizedTypeName) requestType).rawType;
        return (typeName.equals(expectedType));
    }

    return false;
}
