Method removeEntryImpl

output/java_guava/1.4.17/Maps.java:3623–3628

Implements Collection.remove safely for forwarding collections of map entries. If o is an instance of Map.Entry, it is wrapped using #unmodifiableEntry to protect against a possible nefarious equals method. Note that c is backing (delegate) collection, rat

(Collection<Entry<K, V>> c, Object o)

  static <K, V> boolean removeEntryImpl(Collection<Entry<K, V>> c, Object o) {
    if (!(o instanceof Entry)) {
      return false;
    }
    return c.remove(unmodifiableEntry((Entry<?, ?>) o));
  }
