Boolean.toString( ) Method
Flash 5
the value of the Boolean object converted to a string
booleanObject.toString()
Returns
The string "true" if the primitive value of booleanObject is true; "false" if the primitive value of booleanObject is false. The value of the Boolean object is specified when the object is constructed, and it is stored internally thereafter. Although the internal value of a Boolean object is obtainable via valueOf( ), we can use toString( ) to convert it to its string equivalent.
Description
The toString( ) method retrieves the primitive value of a Boolean object, converts that value to a string, and returns the resulting string.
Example
x = new Boolean(true); trace(x.toString()); // Displays: "true"
