		<method name="clear_highlighting_cache">
			<return type="void">

			<description>
				Clears all cached syntax highlighting data.
				Then calls overridable method [method _clear_highlighting_cache].

		</method>
		<method name="get_line_syntax_highlighting">
			<return type="Dictionary">
			</return>
			<argument index="0" name="line" type="int">
			</argument>
			<description>
				Returns syntax highlighting data for a single line. If the line is not cached, calls [method _get_line_syntax_highlighting] to calculate the data.
				The return [Dictionary] is column number to [Dictionary]. The column number notes the start of a region, the region will end if another region is found, or at the end of the line. The nested [Dictionary] contains the data for that region, currently only the key "color" is supported.
				[b]Example return:[/b]
				[codeblock]
				var color_map = {
				    0: {
				        "color": Color(1, 0, 0)
				    },
				    5: {
				        "color": Color(0, 1, 0)
				    }
				}
				[/codeblock]
				This will color columns 0-4 red, and columns 5-eol in green.
