Public class DataTransformationConnection
Represents a connected DataTransformation. The connection is created when the transformation is bound to a DataRowReader that is used as input to the transformation.
Public class DataType
This class contains information about a TIBCO Spotfire data type and the properties of that data type. This is an enumeration class with one static instance for each of the supported data types.
Public class DataValue
An abstract base class for flyweight data value containers. More precisely, a DataValue instance contains a value of a particular DataType, and thus every DataValue has a corresponding DataType. (This is not necessarily true for the methods marked Obsolete in this class.) Instances of the generic subclass are normally used, often explicitly, and this non-generic base class is provided only for convenience in contexts where the generic type is not known, or variable. Note that this class is intended as a flyweight, that is, as a reusable container. This means that it is not optimized for memory and is unsuitable for representing arrays or matrices of data values, where a separate DataValue instance is used for each cell. Consider using a more compact representation of the values for such purposes. The DataValue class is not serializable and should not be used for persistent storage.
Public class DataValue T 
Generic flyweight data value container.
Public class DataValueCollection
A collection of the row values in a IDataColumn.
Public class DataValueCursor
Non-generic cursor class for efficient enumeration of data values.
Public class DataValueCursor T 
Generic cursor class for efficient enumeration of data values.
Public class DataValueProperties
A class holding properties for a data value.
Public class DataValueTuple
Represents a collection of data values that serves as input to produce a result value.
Public class DataView
A DataView is a derived view which values are derived from a DataTable. It cannot be added to the DataTableCollection. A DataView cannot be serialized to the document.
Public class DataView PropertyNames
Contains property name constants for the public properties of DataView.
Public class DistinctDataValue
A wrapper class that holds a value that can occur in the column of a data table. The class provides equality and an ordering of the values even if they are of different underlying types. Values of the class can therefore be used in UndoableList and UndoableDictionary.
Public class HierarchyColumn
An instance of this class can be retrieved from a DataColumn using the As T   method when the column type of the DataColumn is Hierarchy. This class is used for modifying the hierarchy column.
Public class HierarchyDefinition
This is a definition of a hierarchy.
Public class HighlightSelection
This is a highlight selection, it changes when the user moves the mouse cursor over the plots. A highlight selection is a special kind of selection which should only be used from user interface code and the events from this selection can only be received by external event handlers.
Public class HighlightSelection PropertyNames
Contains property name constants for the public properties of DataFilteringSelection.
Public class IndexSet
A bitset-like class that represents a collection of indices, typically a subset of the rows in a IDataColumn or similar.
Public class MutableValueCursor T 
A generic mutable cursor class that should be used when reading data from a DataRowReader.
Public class NameString
Provides static utility methods for validating and creating strings representing names.
These methods should be used when creating names for elements in the data manager, like a data table or a data column.
Public class NodeToRowIndexMap
A mapping between the rows in the column/table and the nodes in a hierarchy level.
Public class PartialDataLoadReport
Represents a report containing error messages from a data loading phase.

This is a wrapper class around a DataView which performs the code for serializing the DataView since a data view is not possible to persist.
Public class PersistentDataView PropertyNames
Contains property name constants for the public properties of PersistentDataView.
Public class ResultColumn
An instance of this class can be retrieved from a DataColumn using the As T   method when the column type of the DataColumn is Result. This class is used for modifying the result column.
Public class ResultProperties
Represents the metadata about the result from a data source, transformation or calculation. These properties are used to set properties on the resulting data table.
Public class RowSelection
This is a representation of a selection of rows in a table. It is currently created from an enumeration of row indexes or IndexSet but may be extended in the future to support symbolic marking.
Public class TagsColumn
An instance of this class can be retrieved from a DataColumn using the As T   method when the column type of the DataColumn is Tags. This class is used for modifying the tags column.
