com.google.gdata.data.geo.GeoLong

All Implemented Interfaces:

Extension

public class GeoLong
extends ValueConstruct

Extension for a W3C geo:long element. It contains the getter/setter for specifying the longitude of a geo-coordinate. The coordinate is contained within the long element as: <geo:long>coordinate</geo:long>. Note that the longitude element does not need to be a child of the geo:Point element. Please see the W3C document http://www.w3.org/2003/01/geo for more information.

Constructor Detail

GeoLong

public GeoLong()

Creates an instance of the GeoLong extension without a longitude value set.

GeoLong

public GeoLong(java.lang.Double lon)
        throws java.lang.IllegalArgumentException

Creates an immutable instance of GeoLong extension with the coordinate set to the value passed in.

Parameters:

lon - The longitude coordinate reprensented by this element.

Throws:

java.lang.IllegalArgumentException - if the longitude is not between -180 and 180 degrees.

Method Detail

getLongitude

public java.lang.Double getLongitude()

Returns the actual double coordinate for longitude. Note this value is not rounded unlike the value returned by getValue().

Returns:

the longitude represented by this element.

setLongitude

public void setLongitude(java.lang.Double longitude)

Sets the longitude represented by this element.

Parameters:

longitude - the longitude of this element.

setValue

public void setValue(java.lang.String value)

Overrides base implementation by validating that the string represents a longitude coordinate between -180 and 180 degrees. Also formats the the string so that it has a consistent number of significant digits after the decimal point.

Overrides:

setValue in class ValueConstruct

Parameters:

value - new value for the value construct or null to reset.
