--- Comment #3 from Yang Sun <eric.sun@huawei.com> ---
I think key or license is very similar, and even you want to update a license
or key, you still need to provide a new key or license.addKey() is very clear
about proivide key or license to CDM, what the confusion comes from?

So I think addKey() is clear enough to express its functionality, using
update() seems confusing me more than addKey(), because app developer will not
clearly know what can be "update" by update().

What's more, in webrtc, we have updateIce(), we also use update, but we know
that we are update configuration of ICE agent.
