Type Annotation Syntax

Kirikiri Z can run TJS with type annotations. Annotations only keep the parser from raising an error; the script behaves exactly the same as without them. They are used, for example, to take advantage of editor IntelliSense.

The syntax looks like the examples below.

Variable declarations

Append a colon to the variable name, followed by the type.

var i:int;
var win:Window = new Window();

Function definitions

Append a colon to an argument name, followed by the type. The return type can be given after the argument list.

function add(param1:int, param2:int) : int {
    return param1 + param2;
}

Function expressions

Argument and return types can be given the same way as in function definitions.

var f = function(param1:string) : void {};

Property definitions

You can specify the type of the setter argument and of the getter return value separately.

property prop {
    setter(value:int) {}
    getter:int { return 0; }
}
