Arney’s Algorithm Previously in Java MathCAD Results Does not match Java Results
State Pattern • Increases extendibility of the program by encapsulating different behaviors that a single class will exhibit into external “state” classes • Reduces large clumps of “if…else” blocks and case statements, thus making the code easier to read and understand
Phidget Controller and Listeners • The Phidgets controller already comes with a library of functions to plug into the program • The program will make use of these various Listener interfaces to implement complete User control of the motors, needed in adjusting zoom, focus, and f-stop
Strategy Pattern • The Strategy pattern will again improve the program’s modularity and extendibility by encapsulating the gloss measurement algorithm as a separate. • Future revisions to the program will allow more than one algorithm to be used and selected amongst others
Builder Pattern • The Builder pattern separates data representation from manipulation so as to de-couple as many class dependencies as possible. • It will be used in the program to efficiently implement a means of providing multiple forms of output using the same resulting data
