Examples of SurfaceValue

com.opengamma.analytics.util.amount.SurfaceValue
Object to represent values linked to a surface (pair of doubles) for which the values can be added or multiplied by a constant. Used for different sensitivities (SABR, FX,...). The objects stored as a HashMap(DoublesPair, Double).
