备注
构造函数:
hash_multimap();
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,使用控制默认排序和哈希函数。
构造函数:
explicit hash_multimap(key_compare^ pred);
初始化控制序列没有元素,并且排序谓词使用默认 pred和哈希函数。 使用它来指定空的初始序列,使用控制指定排序和默认的哈希函数。
构造函数:
hash_multimap(key_compare^ pred, hasher^ hashfn);
初始化控制序列没有元素,并且排序谓词使用 pred和哈希函数hashfn。 使用它来指定空的初始序列,使用控制指定排序和哈希函数。
构造函数:
hash_multimap(hash_multimap<Key, Mapped>% right);
初始化控制序列,使用序列 [right.hash_multimap::begin (STL/CLR)(), right.hash_multimap::end (STL/CLR)()),使用默认排序谓词,和默认哈希函数。 可以使用它来指定初始化的控制序列,该序列是由该hash_multimap对象right控制序列的副本并使用默认的排序谓词和哈希函数。
构造函数:
hash_multimap(hash_multimap<Key, Mapped>^ right);
初始化控制序列,使用序列 [right->hash_multimap::begin (STL/CLR)(), right->hash_multimap::end (STL/CLR)()),使用默认排序谓词,和默认哈希函数。 可以使用它来指定初始化的控制序列,该序列是由该hash_multimap对象right控制序列的副本并使用默认的排序谓词和哈希函数。
构造函数:
template<typename InIter>
hash_multimap(InIter first, InIter last);
初始化控制序列,使用序列 [first, last),使用默认排序谓词,和默认哈希函数。 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_multimap(InIter first, InIter last,
key_compare^ pred);
初始化控制序列,使用序列 [first, last),使用排序谓词 pred,和默认哈希函数。 使用会使控制序列复制另一个序列,其中包含指定排序谓词和默认哈希函数中。
构造函数:
template<typename InIter>
hash_multimap(InIter first, InIter last,
key_compare^ pred, hasher^ hashfn);
初始化控制序列,使用序列 [first, last),使用排序谓词 pred, 和指定哈希函数hashfn. 使用会使控制序列复制另一个序列,其中包含指定排序谓词和哈希函数中。
构造函数:
hash_multimap(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。 使用它来为控制序列创建一个另一个由枚举器指定的序列副本,其中包含默认排序谓词和哈希函数。
构造函数:
hash_multimap(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred);
初始化控制序列的枚举数指定的 right序列,并默认排序谓词pred和具有默认哈希函数。 使用它来为控制序列创建一个另一个由枚举器指定的序列副本,其中包含指定排序谓词和默认哈希函数。
构造函数:
hash_multimap(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred, hasher^ hashfn);
初始化控制序列的枚举数指定的 right序列,并排序谓词pred和具认哈希函数hashfn。 使用它来为控制序列创建一个另一个由枚举器指定的序列副本,其中包含指定排序谓词和哈希函数。
