Class BufferIterator<T>

java.lang.Object
com.github.basking2.sdsai.itrex.iterators.BufferIterator<T>
All Implemented Interfaces:
Iterator<T>
public class BufferIterator<T> extends Object implements Iterator<T>
A buffer iterator pulls elements from a source iterator and store N elements. This is useful when the down-stream may pull data more slowly form us and the up-stream can product data quickly. This is also useful to build a list of Futures and then consume them, though that use is not intrinsic to this class's operation.
