Description

TObjectField encapsulates the fundamental behavior common to fields that are a composite of simpler types. These include ADT fields and array fields, which are built up of subfields, and dataset fields and reference fields, which refer to another dataset. TObjectField introduces the Fields property and the FieldValues property for accessing the subfields that make up the composite (or that reside in the dataset that is the field's value). 

Do not create instances of TObjectField. It is intended only as a base class.
