Class LazyIteratorChain<T>
java.lang.Object
org.apache.jackrabbit.commons.iterator.LazyIteratorChain<T>
- Type Parameters:
T
- type of values iterating over
- All Implemented Interfaces:
- Iterator<T>
public class LazyIteratorChain<T>
- extends Object
- implements Iterator<T>
This class implements the concatenation of iterators. The implementation
is lazy in the sense that advancing of any iterator is deferred as much
as possible. Specifically no iterator is fully unwrapped at one single
point of time.
