JScript does not support generic types and methods.
Type Parameters
- TSource
The type of source.
- TBufferOpening
The type of queryable observable sequence whose elements denote the opening of each produced buffer.
- TBufferClosing
The type of queryable observable sequence whose elements denote the closing of each produced buffer.
Parameters
- source
Type: System.Reactive.Linq.IQbservable<TSource>
The source sequence to produce buffers over.
- bufferOpenings
Type: System.IObservable<TBufferOpening>
The queryable observable sequence whose elements denote the creation of new buffers.
- bufferClosingSelector
Type: System.Linq.Expressions.Expression<Func<TBufferOpening, IObservable<TBufferClosing>>>
The function invoked to define the closing of each produced buffer.
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 .
