Struct amethyst_ui::EventRetriggerSystem

pub struct EventRetriggerSystem<T: EventRetrigger> { /* fields omitted */ }

Links up the given in- and output types' EventChannels listening to incoming events and calling apply on the respective Retrigger components.

Methods

impl<T> EventRetriggerSystem<T> where
    T: EventRetrigger, 

pub fn new(event_reader: ReaderId<T::In>) -> Self

Constructs a default EventRetriggerSystem. Since the event_reader will automatically be fetched when the system is set up, this should always be used to construct EventRetriggerSystems.

Trait Implementations

impl<T: Debug + EventRetrigger> Debug for EventRetriggerSystem<T> where
    T::In: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, 'b, T> SystemDesc<'a, 'b, EventRetriggerSystem<T>> for EventRetriggerSystemDesc<T> where
    T: EventRetrigger, 

fn build(self, world: &mut World) -> EventRetriggerSystem<T>

Builds and returns a System.

impl<'s, T> System<'s> for EventRetriggerSystem<T> where
    T: EventRetrigger, 

type SystemData = (Read<'s, EventChannel<T::In>>, Write<'s, EventChannel<T::Out>>, ReadStorage<'s, T>)

The resource bundle required to execute this system.

fn run(&mut self, (in_channel, out_channel, retrigger): Self::SystemData)

Executes the system with the required system data.

fn running_time(&self) -> RunningTime

Returns a hint how long the system needs for running. This is used to optimize the way they're executed (might allow more parallelization).

fn accessor(&'b self) -> AccessorCow<'a, 'b, Self>

Return the accessor from the [SystemData].

fn setup(&mut self, world: &mut World)

Sets up the World using Self::SystemData::setup.

fn dispose(self, world: &mut World)

Performs clean up that requires resources from the World. This commonly removes components from world which depend on external resources.
