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 flush().
