Description
TStreamProc is a type of callback procedure called used by TFiler and descendant DefineBinaryProperty methods.
DefineBinaryProperty introduces an abstract method that allows descendants to read or write binary 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.
TStreamProc is the callback procedure parameter in that DefineBinaryProperty. When called, it supplies the TFiler or descendant object, allowing binary data read and write access.
