  - - com.saxonica.ee.stream.feed.ItemFeed
    - - com.saxonica.ee.stream.feed.BufferingFeed

All Implemented Interfaces:

javax.xml.transform.Result, Receiver
```
public class BufferingFeed
extends ItemFeed
```
A BufferingFeed is used to wrap an expression that does not have intrinsic capability to accept streamed input. The expression must have been modified to read its input from a SuppliedParameterReference referring to the dynamic context stack. This feed buffers up the streamed input, and on its close() method calls the wrapped expression having placed the buffered input onto the context stack, from where the expression will now read it.
