put method

void put(K key, V value)

Associates the key with the given value.

If the key was already in the cache, its associated value is changed. If the cache is full, the least recently used item is evicted.

Implementation

void put(K key, V value) {
  if (_cache.containsKey(key)) {
    _cache.remove(key);
  } else if (_cache.length >= maxSize) {
    _cache.remove(_cache.keys.first);
  }
  _cache[key] = value;
}
