Microsoft.Office.Server.ApplicationRegistry.Runtime 命名空间

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.

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.

类

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

接口

	接口	说明
	IDataSystemUtility	This class is reserved for future use.
	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.
	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.
	IInstance	Represents an instance in the Business Data Catalog. This class is reserved for future use.
	ISystemUtility	This class is reserved for future use.

枚举

	枚举	说明
	ComparisonFilter.Comparator	Represents the operator in a Comparison filter.
