<brief_description>
Wrapper class for SQLite databases.
</brief_description>
<description>
A wrapper class that lets you perform SQL statements on an SQLite database file.
For queries that involve arbitrary user input, you should use methods that end in [code]*_with_args[/code], as these protect against SQL injection.
</description>
<tutorials>

<methods>
<method name="close">
<return type="void">

<method name="fetch_array">
<return type="Array">
</return>
<argument index="0" name="statement" type="String">
</argument>
<description>
Returns the result of [code]statement[/code] as an [Array] of rows.
Each row is a [Dictionary], and each column can be accessed with either its name or its column position.
