Overview
We have a little conceptual idea of an MVC. And are understanding may be fuzzy, but that is fine, remember iterative learning.
We'll now code up our first MVC application.
Note that most of our work will be in the model for the
reasons discussed here
.
Things To Learn
Even though you may find this example conceptually simple, there is a ton of things to learn including:
class
constructor
method parameters
getter
setter
this
ivars
instance methods
toString
mvc
model
view
controller
intro to debugging
Before Starting -- Ivars 💡
Before we begin our first project, we want to have a fair understanding of
js
ivars, as they can be non-intuitive.
We want to study these topics:
ivars
implicit ivars
Now we're ready to code.
Counter MVC Example
Overview
This is a minimal example that demonstrates input fields, output fields and action buttons.
Model:
Counter
input:
count
output:
count, log
actions:
increment, decrement
Mockup of View
View
Quick mockup of view
Model (Counter)
We'll work in this order: M-V-C.
Model Code
The model source code is listed here...
The public methods are shown here. We will use these in the unit test and also the
ui
.
getters: getCount getLog setters: setCount actions: increment decrement
📋
Test Case
The test case code is listed here...
We should code the test case in parallel with the model.
User Interface (UI)
Once we have the model green (tests passing) we move to the UI:
First we code view
Next the controller
