AccumuloSingleIDRetriever

public AccumuloSingleIDRetriever(AccumuloStore store,
                                 OP operation,
                                 User user,
                                 boolean includeMatchedVertex,

                          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 get operation

user - the user executing the operation

includeMatchedVertex - true if the matched vertex field should be set

iteratorSettings - the iterator settings

Throws:

StoreException - if any store issues occur
