#replace_trigger(new_trigger, timing = :next) ⇒ Object

更新タイミングを計るトリガーオブジェクトを置き換える

現在実行しているトリガーを新しいトリガーオブジェクトに置き換える。 置き換えのタイミングは、以下の2種が選択可能(シンボルで指定)

:immediate

即時に置き換え。現在実行中のトリガーを停止して、引数で指定したトリガーに置き換えて実行を開始する

:next

次回更新時に置き換え。本メソッドが呼ばれた次の更新(updateメソッドが呼ばれた時)にトリガーを置き換える

new_trigger

置き換え対象のトリガーオブジェクト

timing

置き換えのタイミング。:immediateと:nextの2種類がある
