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.
