AccumuloRangeIDRetriever

public AccumuloRangeIDRetriever(AccumuloStore store,
                                OP operation,
                                User user,

                         throws StoreException

Use of the varargs parameter here will mean the usual default iterators wont be applied, (Edge Direction,Edge/Entity TypeDefinition and View Filtering) To apply them pass them directly to the varargs via calling your keyPackage.getIteratorFactory() and either getElementFilterIteratorSetting and/Or getEdgeEntityDirectionFilterIteratorSetting

Parameters:

store - the accumulo store

operation - the operation

user - the user executing the operation

iteratorSettings - the iterator settings

Throws:

StoreException - if any store issues occur
