Class SerialMultiDataIterator

java.lang.Object
org.openspaces.persistency.support.SerialMultiDataIterator
All Implemented Interfaces:
DataIterator, Iterator, MultiDataIterator
public class SerialMultiDataIterator extends Object implements MultiDataIterator
A simple implementation wrapping several iterators and exposing them as a single (serial) iterator.

Note, this implementation assumes that hasNext() is called before next() is called. And that next() is called only when hasNext() returns true.
