lastInstance(): InstanceType;
The lastInstance method of the Class class returns a reference to the last instance of the class.
The code fragment in the following example shows the use of the lastInstance method.
if Customer.firstInstance = null then
instancesTable.text := "0010";
else // add 10 to last one used; that is, sequentially allocate
// the next free Customer number
instancesTable.text := (Customer.lastInstance.customerNumber +
10).String.padLeadingZeros(4);
endif;
