=={{header|Phix}}==

Phix is not object orientated, but this sort of thing is fairly easy to emulate.

<lang Phix>enum METHODS, PROPERTIES

sequence all_methods = {}

function method_visitor(object key, object /*data*/, object /*user_data*/)

all_methods = append(all_methods,key)

return 1

end function

function get_all_methods(object o)

all_methods = {}

traverse_dict(routine_id("method_visitor"),0,o[METHODS])

return all_methods

end function

--class X: Xmethods emulates a vtable

constant Xmethods = new_dict()

function exists()

return "exists"

end function

setd("exists",routine_id("exists"),Xmethods)

--class X: destructor

procedure destructor(object o)

destroy_dict(o[PROPERTIES])

end procedure

constant r_destroy = routine_id("destructor")

--class X: create new instances

function newX(object x,y)

integer Xproperties = new_dict()

setd("x",x,Xproperties)

setd("y",y,Xproperties)

object res = delete_routine({Xmethods,Xproperties},r_destroy)

return res

end function

object x = newX(2,"string")

?get_all_methods(x)</lang>
