co.paralleluniverse.spacebase.geo.GeoRangeQuery<T>

All Implemented Interfaces:

FastSpatialQuery<T>, SpatialQuery<T>, Serializable

public class GeoRangeQuery<T>
extends IntersectGeoGrossGate<T>

A query that finds all elements whose AABBs are completely or partially within a given range from a given AABB. The matching elements do not necessarily lie completely within the range, but their AABBs contain at least one point that lies within the range.

Constructor Detail

GeoRangeQuery

public GeoRangeQuery(Datum datum,
             AABB aabb,
             double range)

Parameters:

aabb - The bounding-box from which the range is measured, in geo coordinates in radians.

range - The range.

Method Detail

toString

public String toString()

Overrides:

toString in class IntersectGeoGrossGate<T>

queryContainer

public co.paralleluniverse.db.tree.QueryResult queryContainer(IndexedAABB aabbs,
                                                     int index)

Description copied from interface: FastSpatialQuery

Called by SpaceBase to inquire whether any of the elements contained in the given AABB may match the query.

Specified by:

queryContainer in interface FastSpatialQuery<T>

Overrides:

queryContainer in class IntersectGeoGrossGate<T>

Parameters:

aabbs - An indexed bounding-box of a group of elements.

index - The index of the bounding box inside the given IndexedAABB

Returns:

A QueryResult specifying whether NONE of the elements within the box matches the query, ALL of them do, or SOME could possibly match.

Overrides:

queryContainer in class IntersectGeoGrossGate<T>

Parameters:

aabb - The bounding-box of the group of elements.

Returns:

A QueryResult specifying whether NONE of the elements within the box matches the query, ALL of them do, or SOME could possibly match.

queryElement

Specified by:

queryElement in interface SpatialQuery<T>

Overrides:

queryElement in class IntersectGeoGrossGate<T>

Parameters:

aabb - The element’s bounding-box.

elem - The element.

Returns:

true if the element matches the query, or false if it does not.
