Returns:

Returns true, if the DataObjects correspond in each value, else returns false

distance

double distance(DataObject dataObject)

Calculates the distance between dataObject and this.dataObject

Parameters:

dataObject - The DataObject, that is used for distance-calculation with this.dataObject

Returns:

double-value The distance between dataObject and this.dataObject

getInstance

Instance getInstance()

Returns the original instance

Returns:

originalInstance

getKey
