Namespace: Cpp

Represents A node in the abstract syntax tree of your code

Since R2026a

Description

node class is a represent a generic node in the syntax tree. it is a super class. All syntax classes have an is a relationship with this class.

Objects of Node classes have access to the predicates in AstNodeProperties. In addition, Node objects have these properties:

Predicates Description

Predicates	Description
`is(required Node &node, Lang.String &kind, Node &parent, Lang.String &field)`	Retrieves a generic syntax node and returns it as `node`. The parent node in the syntax tree of `node` is returned as `parent`. The nature of the node is returned as `kind` and the field name of the node is returned as `field`. For example, consider the node `x` in this code: if (x) { foo(); } Here, for the node `x`: `kind` — identifier `parent` — the condition node `field` — condition
`isNode(required Node &node)`	Checks whether `node` is a generic syntax node.

is(required Node &node, Lang.String &kind, Node
                           &parent, Lang.String &field)

Retrieves a generic syntax node and returns it as node. The parent node in the syntax tree of node is returned as parent. The nature of the node is returned as kind and the field name of the node is returned as field. For example, consider the node x in this code:

if (x) { foo(); }

Here, for the node x:

kind — identifier
parent — the condition node
field — condition

isNode(required Node &node) Checks whether node is a generic syntax node.
