Property storage mechanism.

Declaration

Inheritance

Description

TPropsStorage provides a mechanism to store properties from any class which has published properties (usually a TPersistent descendent) in a storage mechanism.

TPropsStorage does not handle the storage by itself, instead, the storage is handled through a series of callbacks to read and/or write strings. Conversion of property types to string is handled by TPropsStorage itself: all that needs to be done is set the 3 handlers. The storage mechanism is assumed to have the structure of an .ini file : sections with key/value pairs. The three callbacks should take this into account, but they do not need to create an actual .ini file.
