Prevent loading hxi when using encoded expansions

[d.healey]

I'm working on a plugin that loads encoded expansions (hxp). I want to prevent it loading hxis completely so that if the user intercepts the hxi before it has been converted to a hxp they can't do anything with it.

Is this already possible?

Never mind: expHandler.setAllowedExpansionTypes([expHandler.Encrypted]);
