Constructors
| AstAggregateColumnNode(IFrameworkItem) | Initializes a new instance of the AstAggregateColumnNode class with the specified parent node. |
Fields
| IsScopeImported |
Properties
| ComparisonFlags | This value specifies a collection of flags that determine specific behaviors of the Aggregate component when comparing column values. |
| ComparisonFlagsDefaultValue | Gets the default value for the ComparisonFlags property |
| ComposedComparisonFlags | Gets or sets a single ComparisonFlags value that consists of the collection of items in the ComparisonFlags property |
| CountDistinctKeys | This value specifies exactly how many distinct values the transformation can count in a column. If values are specified for both CountDistinctScale and CountDistinctKeys, CountDistinctKeys takes precedence. |
| CountDistinctKeysDefaultValue | Gets the default value for the CountDistinctKeys property |
| CountDistinctScale | This value specifies approximately how many distinct values the transformation can count in a column. The default value is Unspecified. If values are specified for both CountDistinctScale and CountDistinctKeys, CountDistinctKeys takes precedence. |
| CountDistinctScaleDefaultValue | Gets the default value for the CountDistinctScale property |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| Operation | This value specifies which aggregation operation will be used. |
| OperationDefaultValue | Gets the default value for the Operation property |
| Name | Gets or sets the Name of the column mapping, which corresponds directly to the SourceColumn property |
| SourceColumn | This value specifies the name of the source column in the data flow path mapping. |
| TargetColumn | This value specifies the name of the destination column in the data flow path mapping. |
| IsUsed | This value specifies whether the dataflow column is used. |
| SortKeyPosition | This value specifies where the parent column is situated in the sort order. For example if the rows were first sorted by 2 other columns, then the value would be 3. If this column was not used for sorting, it's value should be 0. |
| SourceColumnDefaultValue | Gets the default value for the SourceColumn property |
| TargetColumnDefaultValue | Gets the default value for the TargetColumn property |
| IsUsedDefaultValue | Gets the default value for the IsUsed property |
| SortKeyPositionDefaultValue | Gets the default value for the SortKeyPosition property |
| Guid | |
| Annotations | This is a collection of annotation items that can be used to specify documentation, tags, or other information. Annotations are particularly useful for storing information about nodes that can be used by BimlScript code. |
| ObjectTag | This property provides a general purpose storage mechanism for .NET objects to be associated with AstNode objects. It supplements the annotation system, which is intended for use with string-based metadata. |
| BimlFile | This value specifies the BimlFile in which the Biml code that defines AstNode resides. |
| ItemLabel | Gets a label that can be used to identify this node |
| ParentItem | This value specifies the parent of the current node. All nodes must have a valid parent in the Biml framework, except for the root node. |
