Instance Method Details

#expected_value(base_node) ⇒ String

Get the expected value.

Examples:

if the source code of the node is @id = id,
and the @value is "@{{right_vaue}}",
then it returns "@id".

Parameters:

  • base_node (Node) —

    the base node for evaluated value

Returns:

  • (String) —

    the expected string, if it contains evaluated value, evaluate the node value.

def expected_value(base_node)
  NodeQuery::Helper.evaluate_node_value(base_node, @value, @adapter)
end

#is_equal?(actual, expected) ⇒ Boolean

Check if the actual value equals the node value.

Parameters:

  • node (Node) —

    the node

  • base_node (Node) —
