Cpp.CatchClause Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the catch_clause nodes in the syntax tree of your code

Since R2026a

Description

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 CatchClause &catchClause)`	Finds syntax nodes of the type `CatchClause` in your C++ code and returns them as `catchClause`. For example, in `catch (const std::exception& e) { bar(); }`, this predicate matches the catch clause node.
`isa(Cpp.Node.Node node)`	Checks if `node` is a `CatchClause`. Use this relation if you want to negate the condition (for example: `not Cpp.CatchClause.isa(n)`).
`cast(Cpp.Node.Node node, required CatchClause &cast)`	Finds syntax nodes of the type `CatchClause` from the nodes in `node`. Retrieval occurs if `node` is compatible with the `CatchClause` type. Use this relation if you need further `CatchClause` properties.
`parameters(CatchClause self, Cpp.Node.Node &child)`	Matches the parameter list of the catch clause. For example, in `catch (const std::exception& e) { ... }`, this predicate matches `(const std::exception& e)`.
`body(CatchClause self, Cpp.Node.Node &child)`	Matches the body of the catch clause. For example, in `catch (...) { bar(); }`, this predicate matches `{ bar(); }`.
`isEnclosedInCatchClause(Cpp.Node.Node child)`	Checks if `child` appears inside a `CatchClause`.
`getEnclosingCatchClause(Cpp.Node.Node child, required CatchClause &parent)`	Finds the nearest enclosing `CatchClause` ancestor of `child` and returns it as `parent`.
