Description
TReaderProc is a type of callback procedure called used by TFiler and descendant DefineProperty methods.
DefineProperty introduces an abstract method that allows descendants to read or write data like a property.
Each descendant filer object declares a DefineProperty method that defines the data that the descendant object will read or write as if the data were a property.
TReaderProc is the callback procedure parameter in that DefineProperty. When called, it supplies the TFiler or descendant object, allowing read access.
