Class MapEntrySetStore.SetIterator

  • All Implemented Interfaces:
    java.util.Iterator
    Enclosing class:
    MapEntrySetStore<K,​V>
    public abstract static class MapEntrySetStore.SetIterator
extends java.lang.Object
implements java.util.Iterator
    Inner class representing an iterator for the Set. TODO Provide an option where a PersistentClassROF is provided for key and/or value so we can load fetch plan fields rather than just id.
