StructureProvider

All Known Implementing Classes:

AbstractStructureProvider
```
public interface StructureProvider
```
Provides a structural view of a model. This structure information can be used on client side, typically to allow a user selection as an argument of a service execution. A StructureProvider is contributed using the com.sodius.mdw.server.structureProvider extension point.
Clients may implement this interface. Clients are advised to use AbstractStructureProvider as base implementation.
