Méthodes publiques

Méthode	Description
DSPResourceQueryProvider ( ) : System	Constructor.
GetOpenPropertyValue ( object target, string propertyName ) : object	Gets a value of open property for the specified resource. The method will only be called for properties which are not declared on the resource's resource type. Properties can have null values. The type of the property is determined from the returned object, only primitive types are supported for now.
GetOpenPropertyValues ( object target ) : object>>.IEnumerable	Gets a list of all open properties for the specified resource. This method should only return open properties. Properties declared in metadata for this resource's resource type must not be returned by this method. Properties can have null values. The type of the property is determined from the returned object, only primitive types are supported for now.
GetPropertyValue ( object target, System.Data.Services.Providers.ResourceProperty resourceProperty ) : object	Gets a value of a declared property for a resource. The returned value's type should match the type declared in the resource's resource type.
GetQueryRootForResourceSet ( System.Data.Services.Providers.ResourceSet resourceSet ) : System.Linq.IQueryable	Returns a query which can be used to retrive resource from the specified resource set. The data service will use the LINQ to build the actual query required for the resource set. It's up to this provider to return an IQueryable which can handle such queries. If the resource set is not recognized by the provider it should return null.
GetResourceType ( object target ) : System.Data.Services.Providers.ResourceType	Returns a resource type for the specified resource. The method should throw if the resource is not recognized. If it returns null the data service will throw instead.
InvokeServiceOperation ( System.Data.Services.Providers.ServiceOperation serviceOperation, object parameters ) : object	Invokes the specified service operation.
