Field Details

instancers

protected final Map<InstancerKey<?>,N extends AbstractInstancer<?>> instancers

A map of instancer keys to instancers.

This map is populated as instancers are requested and contains both initialized and uninitialized instancers.

initializationQueue

protected final Queue<DrawManager.UninitializedInstancer<N extends AbstractInstancer<?>,?>> initializationQueue

A list of instancers that have not yet been initialized.

All new instancers land here before having resources allocated in render(dev.engine_room.flywheel.backend.engine.LightStorage, dev.engine_room.flywheel.backend.engine.embed.EnvironmentStorage).

createAndDeferInit

protected final Function<InstancerKey<?>,N extends AbstractInstancer<?>> createAndDeferInit

Function object to pass into computeIfAbsent.

Create once and cache to avoid allocating every time.
