Type Parameters
- TSource
The type of source.
Parameters
- source
Type: System.Reactive.Linq.IQbservable<TSource>
The source sequence to produce buffers over.
- timeSpan
Type: System.TimeSpan
The length of each buffer.
- timeShift
Type: System.TimeSpan
The interval between creation of consecutive buffers.
- scheduler
Type: System.Reactive.Concurrency.IScheduler
The scheduler to run buffering timers on.
Return Value
Type: System.Reactive.Linq.IQbservable<IList<TSource>>
The queryable observable sequence of buffers.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IQbservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
