    Properties

    $container?: AstNode

    The container node in the AST; every node except the root node has a container.

    $containerIndex?: number

    In case $containerProperty is an array, the array index is stored here.

    $containerProperty?: string

    The property of the $container node that contains this node. This is either a direct reference or an array.

    $cstNode?: CstNode

    The Concrete Syntax Tree (CST) node of the text range from which this node was parsed.

    $document?: LangiumDocument<AstNode>

    The document containing the AST; only the root node has a direct reference to the document.

    $type:
        | "AbstractElement"
