Class PointDataImpl

java.lang.Object

com.google.gdata.data.geo.impl.PointDataImpl

All Implemented Interfaces:

PointData

public class PointDataImpl
extends java.lang.Object
implements PointData

Implementation of the PointData interface. Currently only supports a non-repeating Point extension. This class uses an ExtensionPoint that is passed in to store the Point extension.

Constructor Detail

PointDataImpl

public PointDataImpl(ExtensionPoint extensionPoint)

Construct a new implementation of PointData with the given extension point as the backing storage for data.

Method Detail

setGeoLocation

public void setGeoLocation(java.lang.Double lat,
                  java.lang.Double lon)
                    throws java.lang.IllegalArgumentException

Sets the geo-location of the entity based on the lat and long coordinates passed in.

Specified by:

setGeoLocation in interface PointData

Parameters:

lat - The latitude coordinate, between -90 and 90 degrees.

lon - The longitude coordinate, between -180 and 180 degrees.

Throws:

java.lang.IllegalArgumentException - if the latitude and longitude coordinates are invalid.

setGeoLocation

public void setGeoLocation(Point point)

Sets the geo-location of the entity based on the Point extension.

Specified by:

setGeoLocation in interface PointData

Parameters:

point - A point containing the latitude and longitude coordinates.

getGeoLocation

public Point getGeoLocation()

Gets the geo-location of the entity.

Specified by:

getGeoLocation in interface PointData

Returns:

a Point that contains the geo-coordinates (latitude and longitude).

clearPoint

public void clearPoint()

Description copied from interface: PointData

Clears the point data and removes the extension point.

Specified by:

clearPoint in interface PointData

declareExtensions

public void declareExtensions(ExtensionProfile extProfile)

setPoint

public static void setPoint(ExtensionPoint ext,
            Point point)

Sets the geo point of the extension passed in. This will first try to replace any existing point information. If there is no existing point, then it will simply add the point extension.

Parameters:

ext - The extension point to add the Point to.

point - The new point information.

getPoint

public static Point getPoint(ExtensionPoint ext)

Helper method to retrieve the Box extension point.

Parameters:

ext - The containing extension point.

Returns:

An extension point that implements the Box interface and contain box information.

clearPoint

public static void clearPoint(ExtensionPoint ext)

Removes the first Point extension found on the extension point. If the point extension is a GeoRssWhere, it will only remove the GeoRssWhere extension if it does not contain a Box/Envelope extension.

Parameters:

ext - The extension point from which to clear the Box extension.
