-# Concurrent List
+# Thread-Safe Concurrent Container: ArrayList
 
-Create a concurrent `List` structure that can be passed as a thread parameter to sub-threads. It should be visible to other threads when read or written. For detailed features, refer to [Concurrent Map](thread/map.md).
+Creates a concurrent ArrayList structure that can be passed as a parameter to child threads. Read and write operations are visible across threads.
 
-## Usage
-`Thread\ArrayList` implements the `ArrayAccess` interface, so it can be used like an array directly.
-
-## Notes
-- `ArrayList` can only append elements and cannot perform random deletion or assignments.
+## Features
+- `Map`, `ArrayList`, and `Queue` automatically allocate memory and do not require fixed sizing like Table.
+- Built-in locking ensures thread safety at the underlying level.
+- Supported variable types are listed in the Data Types documentation.
+- Iterators are not supported. Use `toArray()` as an alternative.
+- `Map`, `ArrayList`, and `Queue` objects must be passed to child threads as parameters before thread creation.
+- `Thread\ArrayList` implements both the `ArrayAccess` and `Countable` interfaces, allowing array-style operations.
+- Only numeric index access is supported. Non-numeric keys will be forcibly cast to integers.

+## Methods
+
+### __construct()
+
+Initializes the ArrayList. Optionally accepts a list-type array to populate the container.
+```php
+Swoole\Thread\ArrayList::__construct(array $values = [])
+```
+* **Parameters**
+  * `array $valus`: Must be a list-type array (not associative). Use array_values() to convert associative arrays if needed.
+
+### incr()
+
+Atomically increments the value at a given index. If the index does not exist, it is initialized to 0.
+```php
+Swoole\Thread\ArrayList::incr(int $index, mixed $value = 1): int|float
+```
+* **Parameters**
+  * `int $index`: Must be a valid numeric index; otherwise, an exception is thrown.
+  * `mixed $value`: The amount to increment by (default is 1).
+
+### decr()
+
+Atomically decrements the value at a given index. If the index does not exist, it is initialized to 0.
+```php
+Swoole\Thread\ArrayList::decr(int $index, mixed $value = 1): int|float
+```
+* **Parameters**
+  * `int $index`: Must be a valid numeric index; otherwise, an exception is thrown.
+  * `mixed $value`: The amount to decrement by (default is 1).
+
+### count()
+
+Returns the number of elements in the ArrayList.
+```php
+Swoole\Thread\ArrayList::count(): int
+```
+
+* **Return Value**
+  * `int`: Total number of elements.
+
+### toArray()
+
+Converts the ArrayList to a standard PHP array.
+```php
+Swoole\Thread\ArrayList::toArray(): array
+```
+
+* **Return Value**
+  * `array`: All elements in the list.
+
+### clean()
+
+Removes all elements from the ArrayList.
+```php
+Swoole\Thread\ArrayList::clean(): void
+```
+
+### sort()
+
+Sorts the elements in the ArrayList by value. Behavior is consistent with PHP’s `sort()`.
+```php
+Swoole\Thread\ArrayList::sort(): void
+```
