[static]

Returns the class info.

This static function, redefined for each subclass of IlvMapGeometry returns the IlvClassInfo of the class.

Returns:

An IlvClassInfo that should not be modified nor deleted.

Reimplemented from IlvMapArea.

virtual IlBoolean IlvMapRing::contains

(

const IlvCoordinate &

coordinate

)

const [pure virtual]
