Namespace: Cpp
Superclasses: AstNodeProperties

Represents the update_expression nodes in the syntax tree of your code

Since R2026a

Description

The PQL class UpdateExpression represents the node update_expression in the syntax tree of your code.

a = b++ ;

In this code, the update_expression node corresponds to the post-increment operation on a 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 UpdateExpression &ue)`	Retrieves syntax nodes of the type `UpdateExpression` for your C/C++ code and stores it in `ue`.
`isa(Cpp.Node.Node node)`	Checks if `node` is an `update_expression`.
`cast(Cpp.Node.Node node, required UpdateExpression &cast)`	Retrieves syntax nodes of the type `UpdateExpression` from the nodes in `node`. Retrieval occurs if `node` is compatible with `UpdateExpression` type.
`argument(UpdateExpression self, Cpp.Node.Node &child)`	Matches the operand of the update expression.
`operator(UpdateExpression self, Cpp.Node.Node &child)`	Matches the operator node used in the update expression.
`isEnclosedInUpdateExpression (Cpp.Node.Node child)`	Checks if `node` is inside an `update` expression.
`getEnclosingUpdateExpression (Cpp.Node.Node child, required UpdateExpression &parent)`	Finds the nearest `UpdateExpression` ancestor of `node` and returns it as `parent`.
