PoolColorArray
==============

A pooled array of :ref:`Color<class_Color>`\ s.

.. rst-class:: classref-introduction-group

Description
-----------

An array specifically designed to hold :ref:`Color<class_Color>`. Optimized for memory usage, does not fragment the memory.

\ **Note:** This type is passed by value and not by reference. This means that when *mutating* a class property of type **PoolColorArray** or mutating a **PoolColorArray** within an :ref:`Array<class_Array>` or :ref:`Dictionary<class_Dictionary>`, changes will be lost:

::

    var array = [PoolColorArray()]
    array[0].push_back(Color(0.1, 0.2, 0.3, 0.4))
    print(array)  # [[]] (empty PoolColorArray within an Array)

Instead, the entire **PoolColorArray** property must be *reassigned* with ``=`` for it to be changed:

::

    var array = [PoolColorArray()]
    var pool_array = array[0]
    pool_array.push_back(Color(0.1, 0.2, 0.3, 0.4))
    array[0] = pool_array
    print(array)  # [[(0.1, 0.2, 0.3, 0.4)]] (PoolColorArray with 1 element inside an Array)

Method Descriptions
-------------------

.. _class_PoolColorArray_method_PoolColorArray:

.. rst-class:: classref-method

:ref:`PoolColorArray<class_PoolColorArray>` **PoolColorArray** **(** :ref:`Array<class_Array>` from **)**

Constructs a new **PoolColorArray**. Optionally, you can pass in a generic :ref:`Array<class_Array>` that will be converted.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_append:

.. rst-class:: classref-method

void **append** **(** :ref:`Color<class_Color>` color **)**

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

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_append_array:

.. rst-class:: classref-method

void **append_array** **(** :ref:`PoolColorArray<class_PoolColorArray>` array **)**

Appends a **PoolColorArray** at the end of this array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_clear:

.. rst-class:: classref-method

void **clear** **(** **)**

Clears the array. This is equivalent to using :ref:`resize<class_PoolColorArray_method_resize>` with a size of ``0``.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_count:

.. rst-class:: classref-method

:ref:`int<class_int>` **count** **(** :ref:`Color<class_Color>` value **)**

Returns the number of times an element is in the array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_empty:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **empty** **(** **)**

Returns ``true`` if the array is empty.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_fill:

.. rst-class:: classref-method

void **fill** **(** :ref:`Color<class_Color>` color **)**

Assigns the given value to all elements in the array. This can typically be used together with :ref:`resize<class_PoolColorArray_method_resize>` to create an array with a given size and initialized elements.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_find:

.. rst-class:: classref-method

:ref:`int<class_int>` **find** **(** :ref:`Color<class_Color>` value, :ref:`int<class_int>` from=0 **)**

Searches the array for a value and returns its index or ``-1`` if not found. Optionally, the initial search index can be passed. Returns ``-1`` if ``from`` is out of bounds.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_has:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has** **(** :ref:`Color<class_Color>` value **)**

Returns ``true`` if the array contains the given value.

\ **Note:** This is equivalent to using the ``in`` operator.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_insert:

.. rst-class:: classref-method

:ref:`int<class_int>` **insert** **(** :ref:`int<class_int>` idx, :ref:`Color<class_Color>` color **)**

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

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_invert:

.. rst-class:: classref-method

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

Reverses the order of the elements in the array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_push_back:

.. rst-class:: classref-method

void **push_back** **(** :ref:`Color<class_Color>` color **)**

Appends a value to the array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_remove:

.. rst-class:: classref-method

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

Removes an element from the array by index.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_resize:

.. rst-class:: classref-method

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

Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_rfind:

.. rst-class:: classref-method

:ref:`int<class_int>` **rfind** **(** :ref:`Color<class_Color>` value, :ref:`int<class_int>` from=-1 **)**

Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array. If the adjusted start index is out of bounds, this method searches from the end of the array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_set:

.. rst-class:: classref-method

void **set** **(** :ref:`int<class_int>` idx, :ref:`Color<class_Color>` color **)**

Changes the :ref:`Color<class_Color>` at the given index.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_size:

.. rst-class:: classref-method

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

Returns the number of elements in the array.

.. rst-class:: classref-item-separator

----

.. _class_PoolColorArray_method_sort:

.. rst-class:: classref-method

void **sort** **(** **)**

Sorts the elements of the array in ascending order.
