ExtensionMethodsNodeAggregateTValue, TTime Method Naiad Help

[This is preliminary documentation and is subject to change.]

Aggregates the values associated with each node using the given combiner independently for each time.

Namespace: Microsoft.Research.Naiad.Frameworks.GraphLINQ
Assembly: Microsoft.Research.Naiad.GraphLINQ (in Microsoft.Research.Naiad.GraphLINQ.dll) Version: 0.5.0.0 (0.5.0.0)
Syntax
C#
Copy
public static Stream<NodeWithValue<TValue>, TTime> NodeAggregate<TValue, TTime>(
	this Stream<NodeWithValue<TValue>, TTime> nodes,
	Func<TValue, TValue, TValue> combiner
)
where TTime : Object, Time<TTime>

Parameters

nodes
Type: Microsoft.Research.NaiadStreamNodeWithValueTValue, TTime
The stream of nodes with values.
combiner
Type: SystemFuncTValue, TValue, TValue
A function from current value and incoming value, to the new value.

Type Parameters

TValue
The type of value associated with each node.
TTime
The type of timestamp on each record.

Return Value

Type: StreamNodeWithValueTValue, TTime
The stream containing at most one aggregated value for each distinct node in nodes.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type StreamNodeWithValueTValue, TTime. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
This method aggregates values in each locigal time independently. To aggregate across times consider using StateMachineTValue, TState, TTime(StreamNodeWithValueTValue, TTime, FuncTValue, TState, TState).
