Defining Members

Not all class members are created equal. Using special keywords, members can be

configured in various ways, allowing you to specify how the member is accessed and the

scope of its influence. Next, we'll discuss what this means and how you can use this

functionality when creating class members.

Public and Private Members

By default, all members of a class (its properties and methods) are public. This means

that the property or methods of that class can be accessed by instances of that class. Look

again at our State class definition:

class State {

var statePopulation:Number;

function State() {

//Constructor

}

function setPopulation(num:Number) {

statePopulation = num + (num * .05);

}

function getPopulation():Number {

return statePopulation;

}

}
