Class AbstractLongHashMap.DelegatingMapIterator<T>

java.lang.Object

de.uni_hildesheim.sse.monitoring.runtime.utils.AbstractLongHashMap.DelegatingMapIterator<T>

Type Parameters:

T - the element type to iterate over

All Implemented Interfaces:

java.lang.Iterable<T>, java.util.Iterator<T>

Enclosing class:

AbstractLongHashMap

protected abstract static class AbstractLongHashMap.DelegatingMapIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>, java.lang.Iterable<T>

Implements an abstract delegating element iterator. This class is intended to support the realization of value or key iterators. It reuses the map iterator and provides the capability of projecting the result for each individual element. The next method is left open and should be implemented by return iter.next().doSomethingToGetT or equivalently return iter.findNext(true).doSomethingToGetT.
