Methods created in this way, however, do not have access to any private properties or methods
of the Protean class. Moreover, even references to public properties or methods of the
class must be qualified with either the

Data type descriptions
The primitive data types include Boolean, int, Null, Number, String, uint, and void. The
ActionScript core classes also define the following complex data types: Object, Array, Date,
Error, Function, RegExp, XML, and XMLList.
Boolean data type
The Boolean data type comprises two values:
variables of Boolean type. The default value of a Boolean variable that has been declared but
not initialized is
false
int data type
The int data type is stored internally as a 32-bit integer and comprises the set of integers from

offered only the Number data type, which was used for both integers and floating point
numbers. In ActionScript 3.0, you now have access to low-level machine types for 32-bit
signed and unsigned integers. If your variable will not use floating point numbers, using the
int data type instead of the Number data type should be faster and more efficient.
For integer values outside the range of the minimum and maximum int values, use the
Number data type, which can handle values between positive and negative
9,007,199,254,740,992 (53-bit integer values). The default value for variables that are of the
data type int is 0.
