Class ApplicationContext.ResourceCacheDictionary

  • All Implemented Interfaces:
    java.lang.Iterable<java.net.URL>, Dictionary<java.net.URL,​java.lang.Object>
    Enclosing class:
    ApplicationContext
    public static final class ApplicationContext.ResourceCacheDictionary
extends java.lang.Object
implements Dictionary<java.net.URL,​java.lang.Object>, java.lang.Iterable<java.net.URL>
    Resource cache dictionary implementation.

    Note that this implementation does not have a way to limit the number of elements it contains, so the cache continues to grow. To keep it small you have to manually remove old elements from it when they are no longer necessary.
