textInputFocus

Detached identity of the current editable focus interval, or null without committed editable focus.

Created and detached hosts return null, and reattachment requires a successful frame before publishing an interval. Adapters synchronize native input-method focus only after a host operation returns; native notifications may synchronously deliver preedit. The token retains no host, node, or native references.

Throws

when read from another thread, reentrantly, or after terminal failure or close.
