JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.

  • TBufferClosing
    The type of queryable observable sequence whose elements denote the closing of each produced buffer.

Parameters

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 .
