Class ConditionalExistenceCollections.ConditionalExistenceMap<K,​V>

  • Type Parameters:
    K - key type
    V - value type
    All Implemented Interfaces:
    java.util.Map<K,​V>
    Enclosing class:
    ConditionalExistenceCollections
    static final class ConditionalExistenceCollections.ConditionalExistenceMap<K,​V>
extends java.util.AbstractMap<K,​V>
    Mappings in this map only exist if the entry passes some condition.
