Instance Method Details

#resolve(raise_on_reassign = true, reserved = false) ⇒ self, false

Makes the event resolved, which triggers all dependent futures.

Parameters:

  • raise_on_reassign (Boolean) (defaults to: true) —

    should method raise exception if already resolved

  • reserved (true, false) (defaults to: false) —

    Set to true if the resolvable is #reserved by you, marks resolution of reserved resolvable events and futures explicitly. Advanced feature, ignore unless you use Resolvable#reserve from edge.

Returns:

  • (self, false) —

    false is returner when raise_on_reassign is false and the receiver is already resolved.

def resolve(raise_on_reassign = true, reserved = false)
  resolve_with RESOLVED, raise_on_reassign, reserved
end

#wait(timeout = nil, resolve_on_timeout = false) ⇒ self, ...

Behaves as AbstractEventFuture#wait but has one additional optional argument resolve_on_timeout.

Parameters:

  • resolve_on_timeout (true, false) (defaults to: false) —

    If it times out and the argument is true it will also resolve the event.

Returns:

  • (self, true, false)
