Usage

From source file:therian.Operation.java

private static boolean init(Class<?> type) {
    final boolean valid;
    synchronized (type) {
        if (VALID_INFO.containsKey(type)) {
            valid = VALID_INFO.get(type).booleanValue();
        } else if (Modifier.isAbstract(type.getModifiers())) {
            valid = true;//from  w w  w .j av  a2s  . c  om
        } else {
            final Type resultType = TypeUtils.unrollVariables(TypeUtils.getTypeArguments(type, Operation.class),
                    TYPE_VARIABLE_RESULT);
            valid = !TypeUtils.containsTypeVariables(resultType);
            Validate.isTrue(valid, "%s does not fully bind type parameter %s from %s", type,
                    TYPE_VARIABLE_RESULT.getName(), Operation.class);
            VALID_INFO.put(type, Boolean.valueOf(valid));
        }
    }

    final Class<?> parent = type.getSuperclass();
    if (!Operation.class.equals(parent)) {
        init(parent.asSubclass(Operation.class));
    }
    return valid;
