Class MicroMap<K,​V>

  • Type Parameters:
    K - Key type
    V - Value type
    All Implemented Interfaces:
    Serializable, Map<K,​V>
    @Deprecated(forRemoval=true,
            since="9.0.0")
public final class MicroMap<K,​V>
extends Object
implements Map<K,​V>, Serializable
    Deprecated, for removal: This API element is subject to removal in a future version.
    Please use Map.of(Object, Object) instead
    An implementation of the java.util.Map interface which can only hold a single object. This is particularly useful to control memory usage in Wicket because many containers hold only a single component.
