Cpp.CompoundRequirement Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the compound_requirement nodes in the syntax tree of your code

Since R2026a

Description

CompoundRequirement class represents the C++ syntax node compound_requirement 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 CompoundRequirement &cr)	Finds syntax nodes of the type CompoundRequirement in your C++ code and returns them as cr. A CompoundRequirement represents a compound requirement used in C++20 concepts.
isa(Cpp.Node.Node node)	Checks if node is a CompoundRequirement. Use this relation if you want to negate the condition (for example: not Cpp.CompoundRequirement.isa(n)).
cast(Cpp.Node.Node node, required CompoundRequirement &cast)	Finds syntax nodes of the type CompoundRequirement from the nodes in node. Retrieval occurs if node is compatible with the CompoundRequirement type. Use this relation if you need further CompoundRequirement properties.
expression(CompoundRequirement self, Cpp.Node.Node &child)	Matches the expression part of a compound requirement. For example, in { x + y } -> int, this predicate matches the expression x + y.
trailing_return_type(CompoundRequirement self, Cpp.Node.Node &child)	Matches the trailing return type of a compound requirement. For example, in { x + y } -> int, this predicate matches the -> int part.
isEnclosedInCompoundRequirement(Cpp.Node.Node child)	Checks if child appears inside a CompoundRequirement.
getEnclosingCompoundRequirement(Cpp.Node.Node child, required CompoundRequirement &parent)	Finds the nearest enclosing CompoundRequirement ancestor of child and returns it as parent.
