Class ModelCache<A,​B>

  • Type Parameters:
    A - Some Model type that implements Object.equals(java.lang.Object) and Object.hashCode().
    B - Some useful type that may be expensive to create (URL, file path, etc).
    public class ModelCache<A,​B>
extends java.lang.Object
    A simple cache that can be used by ModelLoader and ModelLoaderFactory to cache some data for a given model, width and height. For a loader that takes a model and returns a url, the cache could be used to safely memoize url creation based on the width and height of the view.
