Send, Self and Super

Send, self and super are used to call methods in Classes and instances.

send

can call methods from any class or instance.

self

calls methods from it’s own class or instance’s methods.

super

calls methods from it’s superclass.

Syntax:

(send <ClassName>:
        <MethodName>([params])
        ...
)

If you refer directly to an instance of class, you do not need the send keyword.

Examples:

// you can access classes directly like this...
(ClassX:
        init()
        doit()
)

// you can call it directly...
(SomeInstance:foo())

// or indirectly...
= InstancePtr SomeInstance
(send InstancePtr:foo())

// or a shortcut to the indirect way...
(send (= InstancePtr SomeInstance):foo())

(self:init())

(super:doit())
