Class GeoSearchUtil

java.lang.Object
  no.sesat.search.mode.command.GeoSearchUtil

public final class GeoSearchUtil
extends Object

Utility class for Geographical bounding box and circle transformations. Converts a bounding box to a centerpoint with radius. An example usecase is from map's current bounding box to be able to using the centerpoint with radius to search in this geographical area.

Method Detail

getCenter

public static String getCenter(ParametersDataObject requestParameters)

Calcluates a center point from minX,maxX,minY,maxY parameters. If a centerpoint is given in the request, return new LatLong converted centerpoint.

Parameters:

requestParameters - Parameters for the request.

Returns:

The center point in latlong format.

isGeoSearch

public static boolean isGeoSearch(ParametersDataObject requestParameters)

Responsible for checking if the parameters found in the ParameterDataObject is enough to calculate getCenter(..) getRadiusRestriction(..)

Parameters:

requestParameters -

Returns:

true if the given parameter object contains minX,maxX,minY,maxY values.

hasCenterPoint

public static boolean hasCenterPoint(ParametersDataObject requestParameters)

Responsible for checking if a ParameterDataObject has parameters for centerpoint.

Parameters:

requestParameters - The ParameterDataObject to check.

Returns:

true if the given object has x,y and restriction radius.

getRadiusRestriction

public static String getRadiusRestriction(ParametersDataObject pdo)

Retruns the radius to search from a given centerpoint or map selection.

Parameters:

pdo - The ParameterDataObject.

Returns:

The radius from the centerpoint to search.
