Microsoft.SqlServer.Dts.Pipeline Namespace

The Microsoft.SqlServer.Dts.Pipeline namespace contains managed classes that are used to develop managed data flow components. It contains the PipelineComponent class, which is the base class for managed data flow components, and the PipelineBuffer class, which is the managed implementation of the IDTSBuffer100 interface. The PipelineBuffer class marshals data flow buffers between the COM data flow engine and managed data flow components.

  ClassDescription
Public classBlobColumnDefines a column in a data flow buffer that contains data that has a SQL Server data type of text, ntext, or image.
Public classBufferDisconnectedExceptionThe exception that is thrown when an attempt to access a PipelineBuffer object fails.
Public classBufferNotFoundExceptionThe exception that is thrown when a PipelineBuffer is not found.
Public classCannotCreatePipelineComponentExceptionThe exception that is thrown when the data flow cannot create an instance of a Script component.
Public classCannotCreateUserComponentExceptionException thrown when the Script component cannot instantiate the class that contains the custom code that the developer creates in the Script component. The class is named ScriptMain by default.
Public classColumnIndexOutOfRangeExceptionThe exception that is thrown when an attempt to access a buffer column by using an index is outside the bounds of the collection of buffer columns.
Public classColumnIsNullExceptionThe exception that is thrown when using a specific data type column access method and the column value is null.
Public classComponentUpgradeFailedExceptionThe exception that is thrown when the PerformUpgrade method of a component fails.
Public classComponentVersionMismatchExceptionThe exception that is thrown when the component version stored in the package XML is higher than the version of the component installed on the current computer.
Public classDoesNotFitBufferExceptionThe exception that is thrown when a value that is too large to fit in the data area of a BufferColumn is written to the buffer.
Public classDtsPipelineComponentAttributeContains design-time information about a PipelineComponent object.
Public classInputNotFoundExceptionThe exception that is thrown when the Script Component is unable to find an IDTSInput100 object defined internally by the component.
Public classManagedComponentHostInfrastructure.
Public classNoCurrentRowExceptionThe exception that is thrown when the address of the beginning of a PipelineBuffer row is null.
Public classNotOutputBufferExceptionThe exception that is thrown when a method that is restricted to Output objects is called on an InputPipelineBuffer.
Public classOutputNotFoundExceptionThe exception that is thrown by the ScriptComponent when an IDTSOutput100 cannot be found in its IDTSOutputColumnCollection100.
Public classPipelineBufferProvides an in-memory data store containing rows and columns of data.
Public classPipelineComponentDefines the base class that is used when developing managed data flow components.
Public classPipelineComponentHResultExceptionException raised by the Script component when it encounters a COM exception.
Public classReadOnlyVariablesNotAvailableExceptionException raised by the Script component when the ReadOnlyVariables collection is not available.
Public classReadWriteVariablesNotAvailableExceptionException raised by the Script component when the ReadWriteVariables collection is not available.
Public classRowIndexOutOfRangeExceptionThe exception that is thrown when an invalid index is supplied when accessing a row in a PipelineBuffer.
Public classScriptBufferServes as the base class for the read-only classes representing the input and the outputs that are generated by the Script component in the BufferWrapper project item in a Script component project.
Public classScriptComponentServes as the base class for the read-only UserComponent class generated by the Script component in the ComponentWrapper project item in a Script component project.
Public classScriptComponentHostInfrastructure.
Public classScriptingLanguageNotFoundExceptionThe exception that is thrown by the Script component when the scripting language is not found.
Public classSSISScriptComponentEntryPointAttributeInfrastructure.
Public classUnsupportedBufferDataTypeExceptionThe exception that is thrown when assigning a value to a buffer column that contains the incorrect data type.
Public classUnsupportedDataRecordTypeExceptionThe exception that is thrown when an unsupported parameter value is passed to the DataRecordTypeToBufferType method.
Public classUnsupportedValueTypeForTextStreamColumnExceptionThe exception that is thrown when the type of the value that is being assigned to a column in a PipelineBuffer is not a string or byte array.
Public classVSTAComponentScriptingEngineInfrastructure.

  StructureDescription
Public structureBufferColumnProvides read-only metadata for a PipelineBuffer column.

  InterfaceDescription
Public interfaceIVSTAScriptComponentUIInfrastructure.

  EnumerationDescription
Public enumerationComponentTypeSpecifies the three types of data flow components.
Public enumerationPipelineBufferModeContains values used to identify a PipelineBuffer as an input or output buffer.
