Microsoft.Office.Server.ApplicationRegistry.Runtime, espace de noms

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.

Notes

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.

Classes

  Classe Description
Classe publique AbstractEntityInstance Represents the base class for all entity instances in the Business Data Catalog. This is an abstract class and cannot be instantiated.
Classe publique AbstractInstance Represents the base class for all instances in the Business Data Catalog. This is an abstract class and cannot be instantiated.
Classe publique BackendNullReturnException Represents an exception that is thrown when the back-end method returns null.
Classe publique CannotConnectException Represents an exception that is thrown when the Business Data Catalog cannot successfully make a connection to the back-end business application.
Classe publique ComparisonFilter Represents a filter that limits the instances returned to those that meet the comparison operator condition.
Classe publique ConnectionPoolFullException Represents an exception that is thrown when the maximum number of connections that are modeling in metadata for an LobSystemInstance is exceeded.
Classe publique EntityDataTableAdapter Transforms an IEntityInstanceEnumerator object into a Microsoft ADO.NET DataTable object. Each data row in the table represents an entity instance in the enumerator.
Classe publique EntityInstanceCollection Represents a collection of IEntityInstance objects.
Classe publique EntityInstanceEnumeratorBase Provides a base class for entity instance enumerators in the Business Data Catalog.
Classe publique FilterBase Provides an abstract base class for filters in the Business Data Catalog.
Classe publique FilterCollection Represents 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.
Classe publique LimitFilter Represents a Limit filter in the Business Data Catalog.
Classe publique LobGenericException Represents an exception that occurs when there is a general line-of-business (LOB) error.
Classe publique ObjectNotFoundException Represents an exception that is thrown when the Business Data Catalog cannot find an object.
Classe publique RuntimeException Represents a run-time exception in the Business Data Catalog.
Classe publique SharedEntityState Represents the shared entity state information for an entity's instances.
Classe publique SystemFilter Provides a base class for all system filters in the Business Data Catalog.
Classe publique UserInputFilter Provides a base class for all User Input filters in the Business Data Catalog.
Classe publique WildcardFilter Represents a filter that limits the instances returned to those where field like value, where value may contain the asterisk (*) wildcard character.

Interfaces

  Interface Description
Interface publique IDataSystemUtility This class is reserved for future use.
Interface publique IEntityInstance Represents 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.
Interface publique IEntityInstanceEnumerator Wraps 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.
Interface publique IInstance Represents an instance in the Business Data Catalog. This class is reserved for future use.
Interface publique ISystemUtility This class is reserved for future use.

Énumérations

  Énumération Description
Énumération publique ComparisonFilter.Comparator Represents the operator in a Comparison filter.
