Base Syntax highlighter resource for [TextEdit].
</brief_description>
<description>
Base syntax highlighter resource all syntax highlighters extend from, provides syntax highlighting data to [TextEdit].
The associated [TextEdit] node will call into the [SyntaxHighlighter] on a as needed basis.
[b]Note:[/b] Each Syntax highlighter instance should not be shared across multiple [TextEdit] nodes.

<methods>
<method name="_clear_highlighting_cache" qualifiers="virtual">
<return type="void" />
<description>
Virtual method which can be overridden to clear any local caches.
</description>
</method>
<method name="_get_line_syntax_highlighting" qualifiers="virtual const">
<return type="Dictionary" />
<param index="0" name="line" type="int" />
<description>
Virtual method which can be overridden to return syntax highlighting data.
See [method get_line_syntax_highlighting] for more details.
</description>
</method>
<method name="_update_cache" qualifiers="virtual">
<return type="void" />
<description>
Virtual method which can be overridden to update any local caches.
</description>
</method>
<method name="clear_highlighting_cache">
<return type="void" />
<description>
Clears all cached syntax highlighting data.
Then calls overridable method [method _clear_highlighting_cache].
</description>
</method>
<method name="get_line_syntax_highlighting">
<return type="Dictionary" />
<param index="0" name="line" type="int" />
<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.
</description>
</method>
<method name="get_text_edit">
<return type="TextEdit" />
<description>
Returns the associated [TextEdit] node.
</description>
</method>
<method name="update_cache">
<return type="void" />
<description>
Clears then updates the [SyntaxHighlighter] caches. Override [method _update_cache] for a callback.
[b]Note:[/b] This is called automatically when the associated [TextEdit] node, updates its own cache.
