Constructors
| Name | Description |
|---|---|
| AstDataflowTaskNode(IFrameworkItem) | Initializes a new instance of the AstDataflowTaskNode class with the specified parent node. |
Properties
| Name | Description |
|---|---|
| AutoAdjustBufferSize | This value specifies whether the size of the dataflow pipeline buffer should be set manually using the DefaultBufferSize property or if the buffer size should be automatically calculated based on the DefaultBufferMaxRows property and size of each row. |
| AutoAdjustBufferSizeDefaultValue | Gets the default value for the AutoAdjustBufferSize property |
| BlobTempStoragePath | This value specifies the location for temporary storage of binary large objects. These objects will by default include at least the contents of the TMP and TEMP environment variables. |
| BlobTempStoragePathDefaultValue | Gets the default value for the BlobTempStoragePath property |
| BufferTempStoragePath | This value specifies the location for temporary storage of buffer data. |
| BufferTempStoragePathDefaultValue | Gets the default value for the BufferTempStoragePath property |
| DefaultBufferMaxRows | This value specifies the number of rows that will be stored in the row buffer being processed by the dataflow task. The default value is 10,000 rows. |
| DefaultBufferMaxRowsDefaultValue | Gets the default value for the DefaultBufferMaxRows property |
| DefaultBufferSize | This value specifies the size of the buffer that will be used to store rows being processed by the dataflow task. The default value is 10 megabytes. This value may not exceed 100 megabytes. |
| DefaultBufferSizeDefaultValue | Gets the default value for the DefaultBufferSize property |
| EngineThreads | This value specifies how many threads can be used during execution. The default value is 10. This value may not be set lower than 3. Note that SSIS will only use as many threads as it determines it can use, even if this property is specified to be a higher number. Also note that in some circumstances, SSIS may use more threads than specified, if necessary. |
| EngineThreadsDefaultValue | Gets the default value for the EngineThreads property |
| FriendlyTypeName | Gets the friendly name of the type of this node |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| RunInOptimizedMode | This value specifies whether the task runs in optimized mode, meaning that unused columns, outputs, and components are removed from the data flow to improve performance. The default value is true. |
| RunInOptimizedModeDefaultValue | Gets the default value for the RunInOptimizedMode property |
| SsisAnnotations | This is a collection of SSIS annotations that will be rendered on the SSIS design surface within the parent dataflow object. |
| StaticUserDefinedItems | Specifies a collection of items that are common across all instances of the same type in the framework. |
| Transformations | Container for child dataflow transformations definitions. |
Methods
| Name | Description |
|---|---|
| BindingScopeBoundaries() | Retrieves the permitted scope boundaries to bind references from this node. |
| CanDropItemOfType(Type) | Gets a value to indicate whether items of the specified type can be dropped onto this item in the design surface |
| CopyFrom(IFrameworkItem, UnboundReferences) | Instructs the node to copy property values from the supplied node into itself. This method should only be used by the internal Biml framework. |
| DefinedAstNodes() | Retrieves a collection of nodes that have been defined as direct children of the current node. |
| Duplicate() | Creates a duplicate of the current node |
| Duplicate(Dictionary<IFrameworkItem, IFrameworkItem>) | Creates a duplicate of the current node with the scoped node mapping |
| Duplicate(IFrameworkItem) | Creates a duplicate of the current node with the specified parent item |
| Duplicate(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>) | Creates a duplicate of the current node with the specified parent item and scoped node mapping |
| DuplicateHusk(IFrameworkItem) | Creates an empty object into which the values from the current node will be duplicated. This method should only be used by the internal Biml framework |
| DuplicateInto(IFrameworkItem, Dictionary<IFrameworkItem, IFrameworkItem>) | Copies the values from the current node into a husk object with the specified scoped node mapping. This method should only be used by the internal Biml framework |
| EmitXmlForAction(AstEnginePropertyAction) | Instructs the node to make changes to its underlying Biml code that correspond to the provided action. This method should only be used by the internal Biml framework. |
| EmitXmlForProperty(String, Int32) | Instructs the node to make changes to its underlying Biml code that correspond to the provided property and index. This method should only be used by the internal Biml framework. |
| GetAllItemsReferencedByDefinedSuccessors() | Builds a list of all items referenced by this node and its successors. Each tuple in the returned list represents a FrameworkItemReference. The first item is the ReferencingItem, the second item is the property name, and the third item is the ReferencedItem. |
| GetBimlAttributeFragment(CulturedStringBuilder) | |
| GetBimlChildFragment(CulturedStringBuilder, Int32) | |
| GetBimlFragment(CulturedStringBuilder, Int32, Boolean) | Internal method used by the Biml engine to produce the XML code for the current object. |
| GetDefaultValue(String) | Retrieves the default value for the property with the name propertyName |
| GetDefaultValue<T>(String) | Retrieves the default value for the property with the name propertyName |
| GetJson(StringBuilder, ref Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean) | Generates a JavaScript Object Notation (JSON) representation of the current node |
| GetPotentialParentProperties() | Retrieves the reflection information for related properties of this node type. |
| GetPropertyValue(String) | Retrieves the current value for the property with the name propertyName |
| GetReflectionInfoFromXmlParsePath(String) | Retrieves the reflection information corresponding to the Xml parse path beginning at this node. |
| HasAnyBimlChildNodes() | |
| MergeFrom(IFrameworkItem, UnboundReferences, Boolean) | Instructs the node to merge property values from the supplied node into itself. This method should only be used by the internal Biml framework. |
| NotifyCollectionPropertyChanged(Object, String, NotifyCollectionChangedEventArgs) | Internal Biml framework method used to notify this node that the specified collection property value has changed. |
| ParseAttribute(XAttribute, ParserContext) | |
| ParseChild(XElement, ParserContext) | |
| StructureEquals(Object) | Compares this node to the provided object to determine if all defined children and references are equal. |
