0001180: Need is_subclass_of()

Notes
(0001267) koreth 06-05-06 18:58	Here's an implementation (which I put in ClassesModule) that seems to work. /** * Returns true if one class is a subclass of another. */ public static boolean is_subclass_of(Env env, @ReadOnly Value value, @ReadOnly String className) { QuercusClass clazz; if (value instanceof Var) { Var var = (Var) value; value = var.getRawValue(); } if (value instanceof StringValue) { StringValue str = (StringValue) value; clazz = env.findClass(str.toString()); } else if (value instanceof ObjectValue) { ObjectValue obj = (ObjectValue) value; clazz = obj.getQuercusClass(); } else { return false; } while ((clazz = clazz.getParent()) != null) { if (clazz.getName().equals(className)) return true; } return false; }
