java - Prefered way to reference super classes (typed languages) -


this problem comes quite bit actually. take instance model view. have 2 objects. simulation object , render object.

the class objectrsim (object, designated render sim) like:

class objectrssim {    var simobject:objectsim; }

objectrsim, uses properties/invalidation of objectsim.

there objects inherit objectrsim , objectsim:

posobjectrsim , posobjectsim (positional objects..)

class posobjectrsim extends objectrsim {    var possimobject:posobjectsim; }

or...

class objectrsim {    var simobject:dynamic; //dynamic untyped type haxe, compiler not check calls dynamic object.  }

should have reference each type in inheritance hierarchy of objectsim in objectrsim hierarchy classes, or should use simobject:dynamic?

it totally wrong use dynamic case. it's slow(for every haxe target except javascript guess), not inlined, , used interacting underlying platform or working serialization(yaml, json etc.).

talking solving problem...

if there aren't thousands of objects planned, i'd field lower-level class object. it's not clearest way oop perspective, results in simpler , clearer code me.

casting option(i don't like).

parameterization best way handle that, i'm not sure if have type restricted parameterization in haxe.
