Class AbstractMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>
    Direct Known Subclasses:
    EquivalentHashMap, FastCopyHashMap
    public abstract class AbstractMap<K,​V>
extends java.lang.Object
implements java.util.Map<K,​V>
    Similar to the JDK's AbstractMap, this provides common functionality for custom map implementations. Unlike JDK's AbstractMap, there is no support for null keys.
