Method	Description
AddCollectionProperty ( System.Data.Services.Providers.ResourceType resourceType, string name, System.Data.Services.Providers.ResourceType itemType ) : void	Adds a collection of complex or primitive items property.
AddCollectionProperty ( System.Data.Services.Providers.ResourceType resourceType, string name, Type itemType ) : void	Adds a collection of primitive items property.
AddComplexProperty ( System.Data.Services.Providers.ResourceType resourceType, string name, System.Data.Services.Providers.ResourceType complexType ) : void	Adds a complex property to the specified resourceType.
AddComplexType ( string name ) : System.Data.Services.Providers.ResourceType	Adds a new complex type (without any properties).
AddEntityType ( string name ) : System.Data.Services.Providers.ResourceType	Adds a new entity type (without any properties).

AddResourceReferenceProperty ( System.Data.Services.Providers.ResourceType resourceType, string name, System.Data.Services.Providers.ResourceSet targetResourceSet ) : void	Adds a resource reference property to the specified resourceType. This creates a property pointing to a single resource in the target resource set.
AddResourceSet ( string name, System.Data.Services.Providers.ResourceType entityType ) : System.Data.Services.Providers.ResourceSet	Adds a resource set to the metadata definition.
AddResourceSetReferenceProperty ( System.Data.Services.Providers.ResourceType resourceType, string name, System.Data.Services.Providers.ResourceSet targetResourceSet ) : void	Adds a resource set reference property to the specified resourceType. This creates a property pointing to multiple resources in the target resource set.
Clone ( ) : object
DSPMetadata ( string containerName, string namespaceName ) : System	Creates new empty metadata definition.
GetDerivedTypes ( System.Data.Services.Providers.ResourceType resourceType ) : System.Collections.Generic.IEnumerable	Returns list of all types derived (directly or indirectly) from the specified resourceType. Note that this method will get called even if the HasDerivedTypes returns false. The implementation should be reasonably fast as it can be called to process a query request. (Aside from being called for the $metadata processing).
GetResourceAssociationSet ( System.Data.Services.Providers.ResourceSet resourceSet, System.Data.Services.Providers.ResourceType resourceType, System.Data.Services.Providers.ResourceProperty resourceProperty ) : System.Data.Services.Providers.ResourceAssociationSet	Gets the ResourceAssociationSet instance when given the source association end. This method returns a ResourceAssociationSet representing a reference which is specified by the resourceProperty on the resourceType for instances in the resourceSet.
HasDerivedTypes ( System.Data.Services.Providers.ResourceType resourceType ) : bool	Returns true if the specified type has some derived types. The implementation should be fast as it will get called during normal request processing.
TryResolveResourceSet ( string name, System.Data.Services.Providers.ResourceSet &resourceSet ) : bool	Returnes a resource set specified by its name. The implementation of this method should be very fast as it will get called for almost every request. It should also be fast for non-existing resource sets to avoid possible DoS attacks on the service.
TryResolveResourceType ( string name, System.Data.Services.Providers.ResourceType &resourceType ) : bool	Returnes a resource type specified by its name. The implementation of this method should be very fast as it will get called for many requests. It should also be fast for non-existing resource types to avoid possible DoS attacks on the service.
TryResolveServiceOperation ( string name, System.Data.Services.Providers.ServiceOperation &serviceOperation ) : bool	Returns a service operation specified by its name. The implementation of this method should be very fast as it will get called for many requests. It should also be fast for non-existing service operations to avoid possible DoS attacks on the service.
