Methods

Name Description
BeginInit() Suspends the query schema updates until the EndInit method is called.
CreateObjRef(Type) Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. Inherited from MarshalByRefObject.
Dispose() Releases all resources used by the Component. Inherited from Component.
EndInit() Resumes the query schema updates which are suspended by calling the BeginInit method.
Equals(Object) Determines whether the specified object is equal to the current object. Inherited from Object.
Equals(Object, Object) static Determines whether the specified object instances are considered equal. Inherited from Object.
Fill() Populates the data source with data.
Fill(IEnumerable<IParameter>) Populates the data source with data by running the queries with the specified parameters. Inherited from FederationDataSourceBase.
Fill(IEnumerable<IParameter>, String[]) Populates the data source with data by running the specified queries with the specified parameters. Inherited from FederationDataSourceBase.
Fill(String[]) Populates the data source with data by running the specified queries.
FillAsync() Populates the FederationDataSource in an asynchronous manner.
FillAsync(IEnumerable<IParameter>) Populates the FederationDataSource in an asynchronous manner and passes external parameters to the data source.
FillAsync(IEnumerable<IParameter>, String[]) Populates the FederationDataSource in an asynchronous manner and passes external parameters to the data source. You can specify which queries to execute.
FillAsync(IEnumerable<IParameter>, String[], CancellationToken) Populates the FederationDataSource in an asynchronous manner, passes external parameters to the data source, and uses the cancellationToken parameter to send the cancellation signal. You can specify which queries to execute.
FillAsync(IEnumerable<IParameter>, CancellationToken) Populates the FederationDataSource in an asynchronous manner, passes external parameters to the data source, and uses the cancellationToken parameter to send the cancellation signal.
FillAsync(String[]) Populates the FederationDataSource in an asynchronous manner. You can specify which queries to execute in order to populate the data source.
FillAsync(String[], CancellationToken) Populates the FederationDataSource in an asynchronous manner and uses the cancellationToken parameter to send the cancellation signal. You can specify which queries to execute.
FillAsync(CancellationToken) Populates the FederationDataSource in an asynchronous manner and uses the cancellationToken parameter to send the cancellation signal.
GetHashCode() Serves as the default hash function. Inherited from Object.
GetLifetimeService() Retrieves the current lifetime service object that controls the lifetime policy for this instance. Inherited from MarshalByRefObject.
GetService(Type) Gets the service object of the specified type. Inherited from DataComponentBase.
GetType() Gets the Type of the current instance. Inherited from Object.
InitializeLifetimeService() Obtains a lifetime service object to control the lifetime policy for this instance. Inherited from MarshalByRefObject.
LoadFromXml(XElement) Loads the Federation Data Source schema definition from XML. For internal use. Inherited from FederationDataSourceBase.
MemberwiseClone() protected Creates a shallow copy of the current Object. Inherited from Object.
MemberwiseClone(Boolean) protected Creates a shallow copy of the current MarshalByRefObject object. Inherited from MarshalByRefObject.
RebuildResultSchema() Validates and updates query nodes, joins and conditions in the federated queries.
ReferenceEquals(Object, Object) static Determines whether the specified Object instances are the same instance. Inherited from Object.
