PackedStringArray
=================
:ref:`String<class_String>` 紧缩数组。
.. rst-class:: classref-introduction-group
描述
----
专门设计用于存放 :ref:`String<class_String>` 的数组。数据是紧密存放的，因此能够在数组较大时节省内存。
如果要连接数组中的字符串，请使用 :ref:`String.join<class_String_method_join>`\ 。
::
var string_array = PackedStringArray(["hello", "world"])
var string = " ".join(string_array)
print(string) # "hello world"
.. note::
通过 C# 使用这个 API 时有显著的不同。详见 :ref:`doc_c_sharp_differences`\ 。

:ref:`bool<class_bool>` **append** **(** :ref:`String<class_String>` value **)**
向数组末尾追加一个元素（\ :ref:`push_back<class_PackedStringArray_method_push_back>` 的别名）。
.. rst-class:: classref-item-separator
----

使用二进法查找已有值的索引（如果该值尚未存在于数组中，则为保持排序顺序的插入索引）。传递 ``before`` 说明符是可选的。如果该参数为 ``false``\ ，则返回的索引位于数组中该值的所有已有的条目之后。
\ **注意：**\ 在未排序的数组上调用 :ref:`bsearch<class_PackedStringArray_method_bsearch>` 会产生预料之外的行为。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_clear:
.. rst-class:: classref-method
void **clear** **(** **)**
清空数组。相当于调用 :ref:`resize<class_PackedStringArray_method_resize>` 时指定大小为 ``0``\ 。

.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_fill:
.. rst-class:: classref-method
void **fill** **(** :ref:`String<class_String>` value **)**

.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_has:
.. rst-class:: classref-method
:ref:`bool<class_bool>` **has** **(** :ref:`String<class_String>` value **)** |const|
如果该数组包含 ``value``\ ，则返回 ``true``\ 。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_insert:
.. rst-class:: classref-method
:ref:`int<class_int>` **insert** **(** :ref:`int<class_int>` at_index, :ref:`String<class_String>` value **)**
在数组中给定的位置插入一个新元素。这个位置必须是有效的，或者是在数组的末端（\ ``idx == size()``\ ）。

.. rst-class:: classref-method
:ref:`bool<class_bool>` **push_back** **(** :ref:`String<class_String>` value **)**
在数组的末尾追加字符串元素。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_remove_at:
.. rst-class:: classref-method
void **remove_at** **(** :ref:`int<class_int>` index **)**
从数组中删除位于索引的元素。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_resize:
.. rst-class:: classref-method
:ref:`int<class_int>` **resize** **(** :ref:`int<class_int>` new_size **)**
设置数组的大小。如果数组被增大，则保留数组末端的元素。如果数组被缩小，则将数组截断到新的大小。调用一次 :ref:`resize<class_PackedStringArray_method_resize>` 并分配新值比逐个添加新元素要快。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_reverse:
.. rst-class:: classref-method
void **reverse** **(** **)**
将数组中的元素逆序排列。
.. rst-class:: classref-item-separator

:ref:`int<class_int>` **rfind** **(** :ref:`String<class_String>` value, :ref:`int<class_int>` from=-1 **)** |const|
逆序搜索数组。还可以传递起始搜索位置索引。如果为负，则起始索引被视为相对于数组的结尾。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_set:
.. rst-class:: classref-method
void **set** **(** :ref:`int<class_int>` index, :ref:`String<class_String>` value **)**
更改给定索引处的 :ref:`String<class_String>`\ 。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_size:
.. rst-class:: classref-method
:ref:`int<class_int>` **size** **(** **)** |const|
返回数组中元素的个数。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_slice:
.. rst-class:: classref-method
:ref:`PackedStringArray<class_PackedStringArray>` **slice** **(** :ref:`int<class_int>` begin, :ref:`int<class_int>` end=2147483647 **)** |const|
返回该 **PackedStringArray** 的切片，是从 ``begin``\ （含）到 ``end``\ （不含）的全新 **PackedStringArray**\ 。
\ ``begin`` 和 ``end`` 的绝对值会按数组大小进行限制，所以 ``end`` 的默认值会切到数组大小为止（即 ``arr.slice(1)`` 是 ``arr.slice(1, arr.size())`` 的简写）。
如果 ``begin`` 或 ``end`` 为负，则表示相对于数组的末尾（即 ``arr.slice(0, -2)`` 是 ``arr.slice(0, arr.size() - 2)`` 的简写）。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_method_sort:
.. rst-class:: classref-method
void **sort** **(** **)**
将该数组中的元素按升序排列。
.. rst-class:: classref-item-separator

:ref:`PackedByteArray<class_PackedByteArray>` **to_byte_array** **(** **)** |const|
返回 :ref:`PackedByteArray<class_PackedByteArray>`\ ，每个字符串都被编码为字节。
.. rst-class:: classref-section-separator
----
.. rst-class:: classref-descriptions-group
操作符说明

.. rst-class:: classref-operator
:ref:`bool<class_bool>` **operator !=** **(** :ref:`PackedStringArray<class_PackedStringArray>` right **)**
如果数组内容不同，则返回 ``true``\ 。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_operator_sum_PackedStringArray:
.. rst-class:: classref-operator
:ref:`PackedStringArray<class_PackedStringArray>` **operator +** **(** :ref:`PackedStringArray<class_PackedStringArray>` right **)**
返回新的 **PackedStringArray**\ ，新数组的内容为此数组在末尾加上 ``right``\ 。为了提高性能，请考虑改用 :ref:`append_array<class_PackedStringArray_method_append_array>`\ 。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_operator_eq_PackedStringArray:
.. rst-class:: classref-operator
:ref:`bool<class_bool>` **operator ==** **(** :ref:`PackedStringArray<class_PackedStringArray>` right **)**
如果两个数组的内容相同，即对应索引号的 :ref:`String<class_String>` 相等，则返回 ``true``\ 。
.. rst-class:: classref-item-separator
----
.. _class_PackedStringArray_operator_idx_int:
.. rst-class:: classref-operator
:ref:`String<class_String>` **operator []** **(** :ref:`int<class_int>` index **)**
返回索引为 ``index`` 的 :ref:`String<class_String>`\ 。负数索引能从末尾开始访问元素。使用数组范围外的索引会导致出错。

.. |const| replace:: :abbr:`const (本方法没有副作用。不会修改该实例的任何成员变量。)`
.. |vararg| replace:: :abbr:`vararg (本方法除了在此处描述的参数外，还能够继续接受任意数量的参数。)`
.. |constructor| replace:: :abbr:`constructor (本方法用于构造某个类型。)`
.. |static| replace:: :abbr:`static (调用本方法无需实例，所以可以直接使用类名调用。)`
.. |operator| replace:: :abbr:`operator (本方法描述的是使用本类型作为左操作数的有效操作符。)`
.. |bitfield| replace:: :abbr:`BitField (这个值是由下列标志构成的位掩码整数。)`
