Static Functions and Variables
The syntax for static functions is equal to the one of instance function with the insertion of the keyword
static between the access modifier and the function keyword.
The syntax to declare a static variable is the one depicted in Figure 5 - 5 .
private static var name : Type = assignament;
access
modifier
variable
name
optional value
assignament name
variable
type

Chapter 5: Delving Into Object-Oriented Programming
Values for static variables can be assigned in the variable declaration; when this is the case it is possible
to omit the variable type because the compiler is capable of inferring the correct type from the assigned
value. Contrary to many other languages, the values for static variables are computed during the
execution bootstrap and not when they are first invoked.
