  • hashfn
    對應的金鑰雜湊函式到 Bucket。

  • last

備註

建構函式:

hash_map();

初始化受控制序列中沒有項目,使用預設定序述詞 key_compare()以及預設的雜湊函式。 您會用它來指定一個空的初始控制序列,與預設定序述詞和雜湊函式。

建構函式:

explicit hash_map(key_compare^ pred);

初始化受控制序列中沒有項目,與定序述詞 pred以及預設的雜湊函式。 您會用它來指定一個空的初始控制序列,以指定的順序述詞以及預設的雜湊函式。

建構函式:

hash_map(key_compare^ pred, hasher^ hashfn);

初始化受控制序列中沒有項目,與定序述詞 pred和雜湊函式 hashfn。 您會用它來指定一個空的初始控制序列,以指定的順序述詞和雜湊函式。

建構函式:

hash_map(hash_map<Key, Mapped>% right);

初始化控制序列與序列 [right.hash_map::begin (STL/CLR)(),right.hash_map::end (STL/CLR)()),具有預設定序述詞以及預設的雜湊函式。 您會用它來指定要複製順序由與預設定序述詞和雜湊函式的 right, hash_map 物件的初始控制順序。

建構函式:

hash_map(hash_map<Key, Mapped>^ right);

初始化控制序列與序列 [right->hash_map::begin (STL/CLR)(),right->hash_map::end (STL/CLR)()),具有預設定序述詞以及預設的雜湊函式。 您會用它來指定要複製順序由與預設定序述詞和雜湊函式的 right, hash_map 物件的初始控制順序。

建構函式:

template<typename InIter>

hash_map(InIter first, InIter last);

初始化控制序列與序列 [first,last),具有預設定序述詞以及預設的雜湊函式。 您會用它來做受控制序列複製另一個序列,與預設定序述詞和雜湊函式。

建構函式:

template<typename InIter>

hash_map(InIter first, InIter last,

key_compare^ pred);

初始化控制序列與序列 [first,last),與定序述詞 pred以及預設的雜湊函式。 您會用它來做受控制序列複製另一個序列,以指定的順序述詞以及預設的雜湊函式。

建構函式:

template<typename InIter>

hash_map(InIter first, InIter last,

key_compare^ pred, hasher^ hashfn);

初始化控制序列與序列 [first,last),與定序述詞 pred和雜湊函式 hashfn。 您會用它來做受控制序列複製另一個序列,以指定的順序述詞和雜湊函式。

建構函式:

hash_map(System::Collections::Generic::IEnumerable<Key>^ right);

初始化控制序列與列舉值所指定的 right序列,與預設定序述詞以及預設的雜湊函式。 您會用它來做受控制序列的列舉值所描述的複製另一個序列中,有預設定序述詞和雜湊函式的。

建構函式:

hash_map(System::Collections::Generic::IEnumerable<Key>^ right,

key_compare^ pred);

初始化控制序列與列舉值所指定的順序,與 right定序述詞 pred以及預設的雜湊函式。 您會用它來做受控制序列的列舉值所描述的複製另一個序列,以指定的順序述詞和預設雜湊函式的。

建構函式:

hash_map(System::Collections::Generic::IEnumerable<Key>^ right,

key_compare^ pred, hasher^ hashfn);

初始化控制序列與列舉值所指定的順序,與 right定序述詞 pred和雜湊函式 hashfn。 您會用它來做受控制序列的列舉值所描述的複製另一個序列,以指定的順序述詞和雜湊函式的。
