# Class TDataFieldAccessor
TDataFieldAccessor class TDataFieldAccessor is a utility class that provides access to a field of some data. The accessor attempts to obtain the field value in the following order: If the data is an array, then the field is treated as an array index and the corresponding element value is returned; 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. Since: 3.0 Author: Qiang Xue <qiang.xue@gmail.com>
