 /**
  * Evaluates the data value at the specified field.
  * - If the data is an array, then the field is treated as an array index
  *   and the corresponding element value is returned; the field name can also include
  *   dots to access subarrays. For example a field named 'MyField.MySubField' will
  *   first try to access $data['MyField.MySubField'], then try $data['MyField']['MySubField'].
  * - If the data is a TMap or TList object, then the field is treated as a key
  *   into the map or list, and the corresponding value is returned.
  * - If the data is an object, the field is treated as a property or sub-property
  *   defined with getter methods. For example, if the object has a method called
  *   getMyValue(), then field 'MyValue' will retrieve the result of this method call.
  *   If getMyValue() returns an object which contains a method getMySubValue(),
  *   then field 'MyValue.MySubValue' will return that method call result.
  * @param mixed data containing the field value, can be an array, TMap, TList or object.
  * @param mixed field value
  * @return mixed value at the specified field
  * @throws TInvalidDataValueException if field or data is invalid
