…when(cond) Offer.when(BooleanSupplier) writes the precondition onto the branch it belongs to, as occam, Ada, Erlang and Kotlin do, instead of leaving the association to the position of a flag. It returns a guarded copy, so offers stay immutable and reusable, and guards conjoin — with each other and with the flags of select(boolean...). The condition is a supplier rather than a boolean because it is consulted once per select() call: that is what lets a guarded select be built once and reused as the state it guards on changes. A guarded-off offer is not registered on its channel and keeps its position, and a select with no enabled offer fails with IllegalStateException whether the offers were disabled by guard or by flag. -- This is an automated message from the Apache Git Service.
