Class BoundingBoxFilter

java.lang.Object

org.apache.accumulo.core.iterators.WrappingIterator

org.apache.accumulo.core.iterators.Filter

org.calrissian.accumulorecipes.geospatialstore.support.BoundingBoxFilter

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 BoundingBoxFilter
extends org.apache.accumulo.core.iterators.Filter

This filter will make sure no events pass through if they have geobounds that are no within the range of the given bounding box. This is just in case the quad tree range generation and the precision of overlap allowed do not leak out events that really aren't within the given bounding box.
