Gas-Pump components using a Model-Driven Architecture

Goal

   The goal of this project is to design three different GasPump components using a Model-Driven Architecture (MDA) and then 
   implementation of these GasPump components based on this design.

There are three GasPump components: GasPump-1, GasPump-2 and GasPump-3.

The GasPump-1 component supports the following operations:

• Activate (int a) // the gas pump is activated where a is the price of the gas per gallon
• Start() //start the transaction
• PayCredit() // pay for gas by a credit card
• Reject() // credit card is rejected
• Cancel() // cancel the transaction
• Approved() // credit card is approved
• PayCash(int c) // pay for gas by cash, where c represents prepaid cash
• StartPump() // start pumping gas
• PumpGallon() // one gallon of gas is disposed
• StopPump() // stop pumping gas

The GasPump-2 component supports the following operations:

• Activate (float a, float b) // the gas pump is activated where a is the price of the regular gas // and b is the price of super gas per gallon
• Start() //start the transaction
• PayCredit() // pay for gas by a credit card
• Reject() // credit card is rejected
• Cancel() // cancel the transaction
• Approved() // credit card is approved
• Super() // Super gas is selected
• Regular() // Regular gas is selected
• StartPump() // start pumping gas
• PumpGallon() // one gallon of gas is disposed
• StopPump() // stop pumping gas

The GasPump-3 component supports the following operations:

• Activate (float a, float b) // the gas pump is activated where a is the price of regular gas // and b is the price of premium gas per liter
• Start() //start the transaction
• PayCash(float c) // pay for gas by cash, where c represents prepaid cash
• Cancel() // cancel the transaction
• Premium() // Premium gas is selected
• Regular() // Regular gas is selected
• StartPump() // start pumping gas
• PumpLiter() // one liter of gas is disposed
• StopPump() // stop pumping gas
• Receipt() // Receipt is requested
• NoReceipt() // No receipt
