String Array. Array of strings. Can only contain strings. Optimized for memory usage, can't fragment the memory.

Member Function Description
---------------------------

.. _class_PoolStringArray_PoolStringArray:

- :ref:`PoolStringArray<class_poolstringarray>`  **PoolStringArray**  **(** :ref:`Array<class_array>` from  **)**

Create from a generic array.

.. _class_PoolStringArray_append:

- void  **append**  **(** :ref:`String<class_string>` string  **)**

Append an element at the end of the array (alias of :ref:`push_back<class_PoolStringArray_push_back>`).

.. _class_PoolStringArray_append_array:

- void  **append_array**  **(** :ref:`PoolStringArray<class_poolstringarray>` array  **)**

Append an StringArray at the end of this array.

.. _class_PoolStringArray_insert:

- :ref:`int<class_int>`  **insert**  **(** :ref:`int<class_int>` idx, :ref:`String<class_string>` string  **)**

Insert a new element at a given position in the array. The position must be valid, or at the end of the array (pos==size()).

.. _class_PoolStringArray_invert:

- void  **invert**  **(** **)**

.. _class_PoolStringArray_join:

- :ref:`String<class_string>`  **join**  **(** :ref:`String<class_string>` string  **)**

Reverse the order of the elements in the array (so first element will now be the last).

.. _class_PoolStringArray_push_back:

- void  **push_back**  **(** :ref:`String<class_string>` string  **)**

Append a string element at end of the array.

.. _class_PoolStringArray_remove:

- void  **remove**  **(** :ref:`int<class_int>` idx  **)**

Remove an element from the array by index.

.. _class_PoolStringArray_resize:

- void  **resize**  **(** :ref:`int<class_int>` idx  **)**

Set the size of the StringArray. If larger than the current size it will reserve some space beforehand, and if it is smaller it will cut off the array.

.. _class_PoolStringArray_set:

- void  **set**  **(** :ref:`int<class_int>` idx, :ref:`String<class_string>` string  **)**

Change the :ref:`String<class_string>` at the given index.

.. _class_PoolStringArray_size:

- :ref:`int<class_int>`  **size**  **(** **)**

Return the size of the array.
