The Aggregator2Group type exposes the following members.

Constructors

  NameDescription
Protected methodAggregator2Group
Constructs a new aggregator group.
Top
Properties

  NameDescription
Public propertyEmptyGroupsHaveValue
Gets whether the aggregator produces a value for empty groups.
Public propertyName
Gets the name of the aggregator group.

Methods

  NameDescription
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodTrySpecialize
Returns an aggregator for the specified element type.
Top
Remarks

Use the Aggregator2Group type to represent an aggregation operation that can operate on multiple operand types. This provides a means for specifying an aggregation operation on individual untyped columns of a data frame, or on a data frame as a whole.
