org.calrissian.accumulorecipes.rangestore.iterator.OverlappingScanFilter

All Implemented Interfaces:

org.apache.accumulo.core.iterators.OptionDescriber, org.apache.accumulo.core.iterators.SortedKeyValueIterator<org.apache.accumulo.core.data.Key,org.apache.accumulo.core.data.Value>

public class OverlappingScanFilter
extends org.apache.accumulo.core.iterators.Filter

Filters out all intervals that have an upper bound less than or equal to the criteria upper bound. This should only be run against data that is lower bound indexed.
