Method | find |
Find the first node of a given type. If no such node exists the return value is `None`. |
Method | find |
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 |
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 |
This method iterates over all fields that are defined and yields ``(key, value)`` tuples. Per default all fields are returned, but it's possible to limit that to some fields by providing the `only` parameter or to exclude some using the `exclude` parameter... |
Method | set |
Reset the context of a node and all child nodes. Per default the parser will all generate nodes that have a 'load' context as it's the most common one. This method is used in the parser to set assignment targets and other nodes to a store context. |
Method | set |
Set the environment for all nodes. |
Method | set |
Set the line numbers of the node and children. |

jinja2.nodes.Expr.as_const
Return the value of the expression as constant or raise :exc:`Impossible` if this was not possible. An :class:`EvalContext` can be provided, if none is given a default context is created which requires the nodes to have an attached environment. .. versionchanged:: 2.4 the `eval_ctx` parameter was added.
