    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `addPropertyMutations(Object... keyValues)` This method doesn't do anything as `drop()` doesn't take property mutation arguments.
    `protected boolean` | `filter(Traverser.Admin<S> traverser)`
    `CallbackRegistry<Event>` | `getMutatingCallbackRegistry()` Gets the callback registry for events that the step raises.
