Class Buffer<I,O>

java.lang.Object

org.daisy.common.transform.Buffer<I,O>

public class Buffer<I,O>
extends Object

Buffer to connect two XML transformer ports, one that pushes items and one that pulls items. The buffer is both a XMLInputValue and a XMLOutputValue. It is thread-safe in the sense that one thread can push and another thread can pull. The hasNext and next methods are blocking if a next item is not immediately available but the buffer is not closed yet.
