Cpp.CommaExpression Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the comma_expression nodes in the syntax tree of your code

Since R2026a

Description

The PQL class CommaExpression represents the node comma_expression in the syntax tree of your code.

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 CommaExpression &commaExpression)`	Finds syntax nodes of the type `CommaExpression` in your C/C++ code and returns them as `commaExpression`. For example, in `(foo(), bar())`, this predicate matches the comma expression node for `foo(), bar()`.
`isa(Cpp.Node.Node node)`	Checks if `node` is a `CommaExpression`. Use this relation if you want to negate the condition (for example: `not Cpp.CommaExpression.isa(n)`).
`cast(Cpp.Node.Node node, required CommaExpression &cast)`	Finds syntax nodes of the type `CommaExpression` from the nodes in `node`. Retrieval occurs if `node` is compatible with the `CommaExpression` type. Use this relation if you need further `CommaExpression` properties.
`left(CommaExpression self, Cpp.Node.Node &child)`	Matches the left side of the comma expression. For example, in `foo(), bar()`, this predicate matches `foo()`.
`right(CommaExpression self, Cpp.Node.Node &child)`	Matches the right side of the comma expression. For example, in `foo(), bar()`, this predicate matches `bar()`.
`isEnclosedInCommaExpression(Cpp.Node.Node child)`	Checks if `child` appears inside a `CommaExpression`.
`getEnclosingCommaExpression(Cpp.Node.Node child, required CommaExpression &parent)`	Finds the nearest enclosing `CommaExpression` ancestor of `child` and returns it as `parent`.
