The stream of nodes with values. - restriction
- Type: Microsoft.Research.NaiadStreamNode, TTime
The stream of nodes that should appear in the output.
Type Parameters
- TValue
- The type of value associated with each node.
- TTime
- The type of timestamp on each record.
Return Value
Type: StreamNodeWithValueTValue, TTimeThe filtered stream of nodes with values that contains only nodes that are observed in restriction.
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).See Also
