方法

  名称 说明
公共方法 Cleanup Frees resources and completes the execution of a component.
公共方法 PerformUpgrade Upgrades the component metadata to the version of the component that is installed on the local computer.
公共方法 PostExecute Called at the end of the execution of a component. The developer can supply code that executes after the component's main processing.
公共方法 PreExecute Called after PrepareForExecute, and before PrimeOutput and ProcessInput. The developer can supply code that executes once before the component performs its main processing.
公共方法 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.
公共方法 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.
公共方法 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.

注释

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.
