<dl class="function">
<dt><a name="arrayutil.contains"></a><strong>arrayutil.contains</strong>&nbsp;(array, item, equals)</dt>
<dd>
Gets if the given array contains the given item.
<h3>Parameters</h3>
<ul>
<li>
array: The array to search in.
</li>
<li>
item: The item to search for, can either be an item or another array.
</li>
<li>
equals: Optional. The function to determine if items equal each other, defaults to tableutil.equals.
</li>
</ul>
<h3>Return value:</h3>
true if the array contains the given item.
</dd>
<dt><a name="arrayutil.index"></a><strong>arrayutil.index</strong>&nbsp;(array, item, equals)</dt>
<dd>
Gets the index of the item in the given array.
<h3>Parameters</h3>
<ul>
<li>
array: The array to search in.
</li>
<li>
item: The item to search for, can either be an item or another array.
</li>
<li>
equals: Optional. The function to determine if items equal each other, defaults to tableutil.equals.
</li>
</ul>
<h3>Return value:</h3>
The index of the given item or array, -1 if it was not found.
</dd>
<dt><a name="arrayutil.next_matching_column"></a><strong>arrayutil.next_matching_column</strong>&nbsp;(array, start_index, matcher, reverse)</dt>
<dd>
Finds the next matching column.
<h3>Parameters</h3>
<ul>
<li>
array: The 2D array to search.
</li>
<li>
start_index: Optional. The index at which to start. Defaults to 1, or if the direction is reversed, the number of columns in the array.
</li>
<li>
matcher: Optional. The function that is used to determine if the column matches or not. Is expected to take one argument, the item, and return a boolean. The column matches if any of its items matches this condition. Defaults to not nil and not empty string.
</li>
<li>
reverse: Optional. If the array should be serched backwards. Defaults to false.
</li>
</ul>
<h3>Return value:</h3>
The index of the matching column. -1 if none was found.
</dd>

<dd>
Finds the next matching row.
<h3>Parameters</h3>
<ul>
<li>
array: The 2D array to search.
</li>
<li>
start_index: Optional. The index at which to start. Defaults to 1, or if the direction is reversed, the number of rows in the array.
</li>
<li>
matcher: Optional. The function that is used to determine if the row matches or not. Is expected to take one argument, the item, and return a boolean. The row matches if any of its items matches this condition. Defaults to not nil and not empty string.
</li>
<li>
reverse: Optional. If the array should be serched backwards. Defaults to false.
</li>
</ul>
<h3>Return value:</h3>
The index of the matching row. -1 if none was found.

<dd>
Finds the previous matching column.
<h3>Parameters</h3>
<ul>

array: The 2D array to search.
</li>
<li>
start_index: Optional. The index at which to start. Defaults to the number columns in the array.
</li>
<li>
matcher: Optional. The function that is used to determine if the column matches or not. Is expected to take one argument, the item, and return a boolean. The column matches if any of its items matches this condition. Defaults to not nil and not empty string.
</li>
</ul>
<h3>Return value:</h3>
The index of the matching column. -1 if none was found.

<h3>Parameters</h3>
<ul>
<li>
array: The 2D array to search.
</li>
<li>
start_index: Optional. The index at which to start. Defaults to the number rows in the array.
</li>
<li>
matcher: Optional. The function that is used to determine if the row matches or not. Is expected to take one argument, the item, and return a boolean. The row matches if any of its items matches this condition. Defaults to not nil and not empty string.

<h3>Parameters</h3>
<ul>
<li>
array: The array.
</li>
<li>
is_empty: Optional. The function used for determining if the item is empty. By default nil and an empty string is considered empty. Expected is a function that takes one item and returns a boolean.
