TDynamicProperty Class
Describes a runtime-defined property to be mapped to a database column or association without requiring a compile-time class modification.
Remarks
A dynamic property is stored inside an existing member of the entity class called the container (identified by ContainerName). The property is accessed by its logical name (PropertyName) and typed via PropertyType.
Mapping metadata is attached by calling AddColumn or AddAssociation after construction. Register the completed definition with TMappingExplorer.AddDynamicProperty before the mapping is first loaded.
