Interface PointersSupplier<T>

Type Parameters:
T - the type
public sealed interface PointersSupplier<T>
A supplier of Pointers that allows for the implementation of pointers in a static context without having to manually create a new pointers instance for each instance of a given type.

An example of how this could be implemented is as follows:

public class MyPointeredObject extends SomePointeredParent implements Pointered {
  private static final PointersSupplier<MyPointeredObject> POINTERS = PointersSupplier.builder()
    .parent(SomePointeredParent.POINTERS) // Fallback to the parent to get pointers from.
    .resolving(Identity.UUID, MyPointeredObject::getUniqueId)
    .resolving(Identity.DISPLAY_NAME, MyPointeredObject::getDisplayName)
    .build();

  @Override
  public Pointers pointers() {
    return POINTERS.view(this);
  }
}
