“聪明”的名称是什么？字典（哈希表）？
我正在为自定义字典寻找一个好名称，如果所请求的键不存在，它会使用委托自动初始化该值。索引器实现应该有助于理解它的作用：
public V this[K key]
{
get
{
V value;
if (!_dictionary.TryGetValue(key, out value))
{
value = _defaultValueGenerator(key);
_dictionary[key] = value;
}
return value;
}
set
{
_dictionary[key] = value;
}
}
我的问题不在于代码，代码工作正常，但我似乎找不到此类的正确名称...我想到了 AutoInitDictionary ，但这听起来不对，并且并没有真正传达“所有键都可以假设存在”的想法。
你会如何命名这样一个类？任何建议将不胜感激。
PS：如何使用它的示例：
var charFrequencies = new AutoInitDictionary<char, int>(key => 0);
foreach(char c in text)
charFrequencies[c]++;
I'm looking for a good name for a custom dictionary which automatically initializes the value for a requested key if it doesn't exist, using a delegate. The indexer implementation should help understand what it does :
public V this[K key]
{
get
{
V value;
if (!_dictionary.TryGetValue(key, out value))
{
value = _defaultValueGenerator(key);
_dictionary[key] = value;
}
return value;
}
set
{
_dictionary[key] = value;
}
}
My problem is not about the code, which works fine, but I can't seem to find a proper name for this class... I thought about AutoInitDictionary, but it doesn't sound right, and doesn't really conveys the idea that "all keys can be assumed to exist".
How would you name such a class ? Any suggestion would be appreciated.
PS: an example of how it could be used :
var charFrequencies = new AutoInitDictionary<char, int>(key => 0);
foreach(char c in text)
charFrequencies[c]++;

Python 正是有这种字典，他们称之为
defaultdict< /代码>。Python has exactly this kind of dictionary, and they call it a
defaultdict.我建议使用 FactoryDictionary 选项。
I would suggest FactoryDictionary option.
VirtualDictionary怎么样？所有 4 个定义在某种程度上与您的实现相关。
编辑：即使是
DynamicDictionary也会很好。What about
VirtualDictionary?All 4 definitions somewhat relate to your implementation.
EDIT: Even
DynamicDictionarywill be good.智能词典怎么样？我认为你的主题足够好。 ;)
How about SmartDictionary? I thought your subject was good enough. ;)
全词典？
FullDictionary ?
