## com.saxonica.stream.feed
Class BufferingFeed

    java.lang.Object
      com.saxonica.stream.feed.ItemFeed
          com.saxonica.stream.feed.BufferingFeed

All Implemented Interfaces:
  Feed

    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.

Constructor Summary
`BufferingFeed(Expression expr, Feed result, Stack<XPathContext> contextStack)`

Method Summary
