Description

TFPGInterfacedObjectMap is a generic map class. It can be used to specialize a map for any key type, with associated data type that requires manual reference counting: any type which implements IInterface. For non-reference counted objects, TFPGMap should be used.

This map class is entirely equivalent to TFPGMap, but operates on data items that require additional reference counting code on the data.
