Microsoft.Office.Server.ApplicationRegistry.Runtime Namespace

Contains classes and base classes that offer an intuitive, object-oriented interface to Business Data Catalog client applications.

The Runtime namespace abstracts the underlying data sources and insulates the clients from having to learn application-specific coding paradigms, and allows them to access all business applications in a single, simplified way. When using the Business Data Catalog, the Runtime namespace makes the experience of calling a method on an SAP application feel the same as calling a method on Siebel or executing an SQL query.

NoteNote

The Business Data Catalog does not perform the actual method execution or back-end application plumbing. It merely delegates the client invocation to the appropriate Microsoft ADO.NET provider for databases and Web services proxy for Web services.

The Runtime namespace, with the Microsoft.Office.Server.ApplicationRegistry.MetadataModel, comprises the Runtime object model in the Business Data Catalog. The MetadataModel namespace allows you to read the metadata objects from the metadata database and execute the business logic described in the metadata database. Because it is cached and fast, clients that need only to query the metadata database for metadata information should use the Runtime object model.

  ClassDescription
Public classAbstractEntityInstanceRepresents the base class for all entity instances in the Business Data Catalog. This is an abstract class and cannot be instantiated.
Public classAbstractInstanceRepresents the base class for all instances in the Business Data Catalog. This is an abstract class and cannot be instantiated.
Public classBackendNullReturnExceptionRepresents an exception that is thrown when the back-end method returns a null reference (Nothing in Visual Basic).
Public classCannotConnectExceptionRepresents an exception that is thrown when the Business Data Catalog cannot successfully make a connection to the back-end business application.
Public classComparisonFilterRepresents a filter that limits the instances returned to those that meet the comparison operator condition.
Public classConnectionPoolFullExceptionRepresents an exception that is thrown when the maximum number of connections that are modeling in metadata for an LobSystemInstance is exceeded.
Public classEntityDataTableAdapterTransforms an IEntityInstanceEnumerator object into a Microsoft ADO.NET DataTable object. Each data row in the table represents an entity instance in the enumerator.
Public classEntityInstanceCollectionRepresents a collection of IEntityInstance objects.
Public classEntityInstanceEnumeratorBaseProvides a base class for entity instance enumerators in the Business Data Catalog.
Public classFilterBaseProvides an abstract base class for filters in the Business Data Catalog.
Public classFilterCollectionRepresents a collection of FilterDescriptor objects. A Method can have many filters that are user settable before executing the method. Calling Method.GetFilters returns a FilterCollection of available filters.
Public classLimitFilterRepresents a Limit filter in the Business Data Catalog.
Public classLobGenericExceptionRepresents an exception that occurs when there is a general line-of-business (LOB) error.
Public classObjectNotFoundExceptionRepresents an exception that is thrown when the Business Data Catalog cannot find an object.
Public classRuntimeExceptionRepresents a run-time exception in the Business Data Catalog.
Public classSharedEntityStateRepresents the shared entity state information for an entity's instances.
Public classSystemFilterProvides a base class for all system filters in the Business Data Catalog.
Public classUserInputFilterProvides a base class for all User Input filters in the Business Data Catalog.
Public classWildcardFilterRepresents a filter that limits the instances returned to those where field like value, where value may contain the asterisk (*) wildcard character.

  InterfaceDescription
Public interfaceIDataSystemUtilityThis class is reserved for future use.
Public interfaceIEntityInstanceRepresents instances of business objects, for example, customer #88697 and order #1000 in a back-end business application. The most important implementor of this interface is AbstractEntityInstance, which in turn is subclassed by WebServiceEntityInstance and DbEntityInstance.
Public interfaceIEntityInstanceEnumeratorWraps a native object returned by the back-end that represents a collection or a stream as entity instances and supports a single iteration over the entity instance collection.
Public interfaceIInstanceRepresents an instance in the Business Data Catalog. This class is reserved for future use.
Public interfaceISystemUtilityThis class is reserved for future use.

  EnumerationDescription
Public enumerationComparisonFilter.ComparatorRepresents the operator in a Comparison filter.
