Overrides:

finalize in class Object

Throws:

Throwable

onStreamClosed

public CompletionStage<Void> onStreamClosed()

Returns a future that completes when the underlying OutputStream has been closed. Importantly, calling this method does not trigger the close process. Callers are expected to call close().
