The IRepositoryDispatch interface is an enhanced IDispatch interface; in addition to all of the standard IDispatch methods, IRepositoryDispatch also provides access to the Properties collection. The Properties collection gives you a convenient mechanism to enumerate through all of the persistent properties and collections of an interface.
When you instantiate an Automation object that represents an object from your information model, and that object conforms to a class for which there is no custom implementation (in other words, you have provided no software implementation of the class), Microsoft® Repository will provide an interface implementation for you. This interface implementation uses IRepositoryDispatch as its dispatch interface.
Use the IRepositoryDispatch interface to access the properties and collections of a Repository object, when no custom implementation is available.
| IUnknown Method | Description |
| QueryInterface | Returns pointers to supported interfaces. |
| AddRef | Increments the reference count. |
| Release | Decrements the reference count. |
| IDispatch Method | Description |
| GetIDsOfNames | Maps a single member and a set of argument names to a corresponding set of dispatch identifiers. |
| GetTypeInfo | Retrieves a type information object, which can be used to get the type information for an interface. |
| GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). |
| Invoke | Provides access to properties and methods exposed by an Automation object. |
| IRepositoryDispatch Method | Description |
| get_Properties | Retrieves the IReposProperties interface pointer. The IReposProperties interface provides access to the Properties collection. |
The Repository engine will only supply an interface implementation for you if your interface is defined to inherit from IDispatch or IRepositoryDispatch.
