Almost any custom object can support calculations implementing Essential Calculate's ICalcData interface.

Essential Calculate lets you add calculation support to objects by implementing an interface, ICalcData. CalcQuick and CalcDataGrid both implement ICalcData which gives them their calculation support. ICalcData is designed around a rectangular array of data. But you can hide this rectangular design as CalcQuick does.

There are only four members of the ICalcData interface, three methods and one event.

Two of the methods are used to get and set values, one method gives you access to the object after it has been created, and the event is used to notify listeners when values change.
