Свойства

	Имя	Описание
	BufferManager	Sets the IDTSBufferManager100 of a pipeline component.
	ComponentMetaData	Sets the IDTSComponentMetaData100 for a component.
	EventInfos	Sets the IDTSEventInfos100 collection of the PipelineComponent object.
	LogEntryInfos	Provides the IDTSLogEntryInfos100 object to a component.
	ReferenceTracker	Sets the IDTSObjectReferenceTracker100.
	RequiredProductLevel	Gets a value indicating the required SQL Server product level for the data flow component.
	VariableDispenser	Sets the IDTSVariableDispenser100 of a data flow component.

Методы

	Имя	Описание
	Cleanup	Frees resources and completes the execution of a component.
	PerformUpgrade	Upgrades the component metadata to the version of the component that is installed on the local computer.
	PostExecute	Called at the end of the execution of a component. The developer can supply code that executes after the component's main processing.
	PreExecute	Called after PrepareForExecute, and before PrimeOutput and ProcessInput. The developer can supply code that executes once before the component performs its main processing.
	PrepareForExecute	Called prior to PreExecute. The developer can supply code that executes once before the component performs its main processing and before the input buffers are available.
	PrimeOutput	Called during package execution for components that add rows to the IDTSBuffer100; including source components and transformation components with asynchronous IDTSOutput100 objects. The developer needs to supply the code that adds the rows to the output buffers.
	ProcessInput	Called on transformation and destination components that have IDTSInput100 objects that are connected to an upstream component. The developer needs to supply the code that processes the input buffers.

Замечания

The IDTSRuntimeComponent100 interface defines the methods and properties that are called during execution of a data flow component. This interface is one of the two interfaces that all data flow components implement; the other is the IDTSDesigntimeComponent100 interface.

Managed component developers do not need to implement this interface directly but instead derive the methods from the PipelineComponent base class and override its implementation of these methods.
