Overview

Handle returned by #tick. Mirrors the public surface of EventQueue::Ticker (‘cancel`, `cancelled?`) but does not auto-fire —the host Tuile::FakeEventQueue drives firing via #tick_once.

Instance Method Details

#cancel ⇒ void

This method returns an undefined value.

Marks the ticker cancelled. Idempotent. Subsequent #fire calls are no-ops; Tuile::FakeEventQueue#tick_once also prunes the ticker on its next pass.

def cancel
  @cancelled = true
end

#cancelled? ⇒ Boolean

Returns true once #cancel has been called.

Returns:

  • (Boolean) —

    true once #cancel has been called.

def cancelled? = @cancelled

#fire ⇒ void

This method returns an undefined value.

Invokes the user block with the current tick counter, then advances. No-op when #cancelled?. Typically driven by Tuile::FakeEventQueue#tick_once; safe to call directly from a test that wants to drive a single ticker.
