Cpp.UnaryExpression Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the unary_expression nodes in the syntax tree of your code

Since R2026a

Description

The PQL class UnaryExpression represents the node unary_expression in the syntax tree of your code.

int x = +1;

In this code, the unary_expression node corresponds to the unary operator applied to the operand +1 in the C++ source.

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 UnaryExpression &ue)`	Retrieves syntax nodes of the type `UnaryExpression` for your C/C++ code and stores it in `ue`.
`isa(Cpp.Node.Node node)`	Checks if `node` is a `unary_expression`.
`cast(Cpp.Node.Node node, required UnaryExpression &cast)`	Retrieves syntax nodes of the type `UnaryExpression` from the nodes in `node`. Retrieval occurs if `node` is compatible with `UnaryExpression` type.
`operator(UnaryExpression self, Cpp.Node.Node &op)`	Matches the operator node used in the `unary` expression.
`operand(UnaryExpression self, Cpp.Node.Node &op)`	Matches the operand of the `unary` expression.
`argument(UnaryExpression self, Cpp.Node.Node &child)`	Matches the operand of the `unary` expression.
`isEnclosedInUnaryExpression (Cpp.Node.Node child)`	Checks if `node` is inside a `unary` expression.
`getEnclosingUnaryExpression (Cpp.Node.Node child, required UnaryExpression &parent)`	Finds the nearest `UnaryExpression` ancestor of `node` and returns it as `parent`.
