For interfaces and abstract methods it is generally a good practice to add a @return annotation even if it is just @return void or @return null, so that implementors know what to do in the overridden method.

	/**
	 * Pre-parser
	 *
	 * The bbcode you receive is already sanitized, which means: a
	 * ny replacements you do here won't be sanitized any further. Take care!
	 * Do anything here to the unparsed bbcode, just don't touch newlines
	 * - these will be replaced with a placeholder after this step.
	 *
	 * @param string $bbcode bbcode
	 *
	 * @return string preparsed bbcode
	 */
	public function pre(string $bbcode):string;

	/**
	 * Post-parser
	 *
	 * Use this method in case you want to alter the parsed bbcode.
	 * The newline placeholders are still available and any remaining will
	 * be removed in the last step before output
	 *
	 * Example: you want the "img" bbcode to use database images instead of user URLs.
	 * You'd replace any occurence with a unique placeholder like {__IMG#ID__}.
	 * Now the post-parser gets into play: you preg_match_all() out all your placeholders,
	 * grab the images in a single query from the database and replace them with their respective <img> tag
	 * or whatever replacement and any corrupt id with a placeholder image. Profit!
	 *
	 * @param string $bbcode bbcode
	 *
	 * @return string postparsed bbcode
