net.markenwerk.commons.iterators.SuffixedIterator<Payload>

Type Parameters:

Payload - The payload type.

All Implemented Interfaces:

Iterator<Payload>

public final class SuffixedIterator<Payload>
extends Object
implements Iterator<Payload>

A SuffixedIterator is an Iterator that can be wrapped around a given Iterator and yields some given suffix values after yielding all values yielded by the given Iterator.

Calling AbstractProtectedIterator.remove() calls Iterator.remove() removed on the wrapped Iterator, if, and only iff, the last call to AbstractIndexedIterator.next() didn't return a suffix value.

2.1.0
