useAll

Runs block and then closes every resource in resources in reverse order.

The multi-resource counterpart of kotlin.use. Reverse order means the resource listed last, which is typically the one layered on top of the others, is closed first. Every resource is closed exactly once regardless of how many closes fail.

Failure handling uses Throwable.addSuppressed, which common Kotlin provides on every target:

• When block throws, that exception is rethrown and every close failure is attached to it as a suppressed exception.

• When block succeeds but closing fails, the first close failure (in the reverse close order) is thrown after all remaining resources have been closed, with any later close failures attached to it as suppressed exceptions.

Note that on platforms whose suppressed-exception support is a stdlib emulation the suppressed list is still populated; no failure is ever silently dropped.

useAll(source, buffer, cipher) { cipher.process(buffer.read(source)) }

Parameters

Runs block and then closes every resource in this collection in reverse iteration order.

Behaves exactly like the vararg useAll overload, including its reverse close order and its suppression rules; see that overload for the details.
