备注
构造函数:
hash_map();
初始化控制序列没有元素,并且默认排序谓词使用默认 key_compare()和哈希函数。 使用它来指定空的初始序列,以控制默认排序谓词和哈希函数中。
构造函数:
explicit hash_map(key_compare^ pred);
初始化控制序列没有元素,与顺序的谓词使用默认 pred和哈希函数。 使用该指定一个空控件,使用初始序列指定顺序的谓词和默认哈希函数。
构造函数:
hash_map(key_compare^ pred, hasher^ hashfn);
初始化控制序列没有元素,与顺序的谓词使用哈希函数 pred和 hashfn。 使用该指定一个空控件,使用初始序列指定顺序的谓词和哈希函数。
构造函数:
hash_map(hash_map<Key, Mapped>% right);
初始化控制序列的序列 [right.(), right.hash_map::end (STL/CLR)hash_map::begin (STL/CLR)()),而默认排序谓词和具有默认哈希函数。 将它指定为复制由其中的顺序控制默认 hash_map right对象排序,谓词和哈希函数的初始序列控制。
构造函数:
hash_map(hash_map<Key, Mapped>^ right);
初始化控制序列的序列 [right->(), right->hash_map::end (STL/CLR)hash_map::begin (STL/CLR)()),而默认排序谓词和具有默认哈希函数。 将它指定为复制由其中的顺序控制默认 hash_map right对象排序,谓词和哈希函数的初始序列控制。
构造函数:
template<typename InIter>
hash_map(InIter first, InIter last);
初始化控制序列的序列 [first, last),其默认排序谓词和具有默认哈希函数。 使用会使控制序列复制另一个序列,其中包含默认排序谓词和哈希函数中。
构造函数:
template<typename InIter>
hash_map(InIter first, InIter last,
key_compare^ pred);
初始化控制序列的序列 [first, last),其顺序的谓词使用默认 pred和哈希函数。 使用会使控制序列复制其他序列,具有指定顺序的谓词和默认哈希函数。
构造函数:
template<typename InIter>
hash_map(InIter first, InIter last,
key_compare^ pred, hasher^ hashfn);
初始化控制序列的序列 [first, last),其顺序的谓词使用哈希函数 pred和 hashfn。 使用会使控制序列复制其他序列,具有指定顺序的谓词和哈希函数。
构造函数:
hash_map(System::Collections::Generic::IEnumerable<Key>^ right);
初始化控制序列的枚举数指定的 right序列,并默认排序谓词和具有默认哈希函数。 使用会使控制枚举数的序列描述复制另一个序列,其中包含默认排序谓词和哈希函数。
构造函数:
hash_map(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred);
初始化控制序列的枚举数指定的序列排序的谓词,right与 pred和与默认哈希函数。 使用会使控制枚举数的序列描述复制其他序列,具有指定顺序的谓词以及默认的哈希函数。
构造函数:
hash_map(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred, hasher^ hashfn);
初始化控制序列的枚举数的序列排序的谓词指定 right,与 pred和与哈希函数 hashfn。 使用会使控制枚举数的序列描述复制其他序列,具有指定顺序的谓词和哈希函数的。
