Class ReadOnlyArrayMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>

    public final class ReadOnlyArrayMap<K,​V>
    extends java.util.AbstractMap<K,​V>
    A read-only view of an array of key-value pairs.

    This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.
