Re: [icu-design] Proposal for new way of setting callbacks in ICU4J

[Markus S. <mar...@gm...>]

The reason we use "context" parameters in C callbacks is that we are
trying to emulate passing an object (context=object pointer) and a
function that operates on that object.

If in Java the callback itself is an object (or an interface) then you
should not need a separate context reference/pointer. API-using code
should be able to instantiate an object of the right type and with the
desired context information and set that as the callback object.
