- 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.
