Class Variable	`abstract`	Undocumented

Inherited from Node (via Expr):

Method	`find`	Find the first node of a given type. If no such node exists the return value is `None`.
Method	`find_all`	Find all the nodes of a given type. If the type is a tuple, the check is performed for any of the tuple items.
Method	`iter_child_nodes`	Iterates over all direct child nodes of the node. This iterates over all fields and yields the values of they are nodes. If the value of a field is a list all the nodes in that list are returned.
Method	`iter_fields`	No summary
Method	`set_ctx`	No summary
Method	`set_environment`	Set the environment for all nodes.
Method	`set_lineno`	Set the line numbers of the node and children.

overrides jinja2.nodes.Expr.as_const

An EvalContext can be provided, if none is given a default context is created which requires the nodes to have an attached environment.

Changed in version 2.4: the eval_ctx parameter was added.
