Class MeasurableLinkedHashMap<K,​V extends Measurable>

  • All Implemented Interfaces:
    Measurable, java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​V>
    public class MeasurableLinkedHashMap<K,​V extends Measurable>
extends java.util.LinkedHashMap<K,​V>
implements Measurable
    A subclass of LinkedHashMap which does a best-effort attempt at guessing its size on heap + the size of its values. Several assumptions are made which could make this imprecise in some contexts. See the usage in PubSubMessageHeaders for the usage it was originally intended for...
