Cpp.Attribute Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the attribute nodes in the syntax tree of your code

Since R2026a

Description

Attribute class represents the C++ syntax node attribute in your code and contains predicates to query properties and children of this node.

Syntaxes

This class defines these predicates that act on the objects of this class. In addition, objects of this class can access the predicates defined by the base class AstNodeProperties. An object of this class is an object of AstNodeProperties class.

Predicates	Description
`is(required Attribute &attribute)`	Finds syntax nodes of the type `Attribute` in your C++ code and returns them as `attribute`. For example, in `[[nodiscard]]`, this predicate matches the `nodiscard` attribute node.
`isa(Cpp.Node.Node node)`	Checks if `node` is an `Attribute`. Use this relation if you want to negate the condition (for example: `not Cpp.Attribute.isa(n)`).
`cast(Cpp.Node.Node node, required Attribute &cast)`	Finds syntax nodes of the type `Attribute` from the nodes in `node`. Retrieval occurs if `node` is compatible with the `Attribute` type. Use this relation if you need further `Attribute` properties.
`name(Attribute self, Cpp.Node.Node &child)`	Matches the attribute name. For example, in `[[nodiscard]]`, this predicate matches `nodiscard`.
`prefix(Attribute self, Cpp.Node.Node &child)`	Matches the attribute prefix, when present. For example, in `[[gnu::always_inline]]`, this predicate matches `gnu`.
`argumentList(Attribute self, Cpp.Node.Node &child)`	Matches the argument list of the attribute, when present. For example, in `[[deprecated("use bar instead")]]`, this predicate matches `("use bar instead")`.
`isEnclosedInAttribute(Cpp.Node.Node child)`	Checks if `child` appears inside an `Attribute`.
`getEnclosingAttribute(Cpp.Node.Node child, required Attribute &parent)`	Finds the nearest enclosing `Attribute` ancestor of `child` and returns it as `parent`.
