Cpp.DeclarationList Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the declaration_list 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 DeclarationList &declarationList)`	Finds syntax nodes of the type `DeclarationList` in your C/C++ code and returns them as `declarationList`. A `DeclarationList` groups multiple top-level or block-level declarations. For example, a list may contain a variable declaration, a function definition, and a namespace definition.
`isa(Cpp.Node.Node node)`	Checks if `node` is a `DeclarationList`. Use this relation if you want to negate the condition (for example: `not Cpp.DeclarationList.isa(n)`).
`cast(Cpp.Node.Node node, required DeclarationList &cast)`	Finds syntax nodes of the type `DeclarationList` from the nodes in `node`. Retrieval occurs if `node` is compatible with the `DeclarationList` type. Use this relation if you need further `DeclarationList` properties.
`declaration(DeclarationList self, Cpp.Node.Node &child)`	Matches a (non-template) declaration that appears as a direct child of the declaration list (for example, `int x;`).
`functionDefinition(DeclarationList self, Cpp.Node.Node &child)`	Matches a function definition that appears as a direct child of the declaration list (for example, `void foo() {}`).
`namespaceDefinition(DeclarationList self, Cpp.Node.Node &child)`	Matches a namespace definition that appears as a direct child of the declaration list (for example, `namespace N {}`).
`namespaceAliasDefinition(DeclarationList self, Cpp.Node.Node &child)`	Matches a namespace alias definition that appears as a direct child of the declaration list.
`linkageSpecification(DeclarationList self, Cpp.Node.Node &child)`	Matches a linkage specification that appears as a direct child of the declaration list (for example, `extern "C" { ... }`).
`templateDeclaration(DeclarationList self, Cpp.Node.Node &child)`	Matches a template declaration that appears as a direct child of the declaration list.
`templateInstantiation(DeclarationList self, Cpp.Node.Node &child)`	Matches a template instantiation that appears as a direct child of the declaration list.
`typeDefinition(DeclarationList self, Cpp.Node.Node &child)`	Matches a type definition that appears as a direct child of the declaration list (for example, `struct S { ... };` or `typedef ...;`).
`typeSpecifier(DeclarationList self, Cpp.Node.Node &child)`	Matches a type specifier that appears as a direct child of the declaration list.
`usingDeclaration(DeclarationList self, Cpp.Node.Node &child)`	Matches a `using` declaration that appears as a direct child of the declaration list.
`aliasDeclaration(DeclarationList self, Cpp.Node.Node &child)`	Matches an alias declaration that appears as a direct child of the declaration list (for example, `using Foo = Bar;`).
`conceptDefinition(DeclarationList self, Cpp.Node.Node &child)`	Matches a C++20 concept definition that appears as a direct child of the declaration list.
`staticAssertDeclaration(DeclarationList self, Cpp.Node.Node &child)`	Matches a `static_assert` declaration that appears as a direct child of the declaration list.
`statement(DeclarationList self, Cpp.Node.Node &child)`	Matches a statement that appears as a direct child of the declaration list (this can occur in certain contexts where statements are permitted among declarations).
`preprocCall(DeclarationList self, Cpp.Node.Node &child)`	Matches a preprocessor call-like construct that appears as a direct child of the declaration list.
`preprocDef(DeclarationList self, Cpp.Node.Node &child)`	Matches a preprocessor definition that appears as a direct child of the declaration list (for example, `#define ...`).
`preprocFunctionDef(DeclarationList self, Cpp.Node.Node &child)`	Matches a function-like preprocessor definition that appears as a direct child of the declaration list.
`preprocIf(DeclarationList self, Cpp.Node.Node &child)`	Matches a preprocessor `#if` construct that appears as a direct child of the declaration list.
`preprocIfdef(DeclarationList self, Cpp.Node.Node &child)`	Matches a preprocessor `#ifdef`/`#ifndef` construct that appears as a direct child of the declaration list.
`preprocInclude(DeclarationList self, Cpp.Node.Node &child)`	Matches a preprocessor `#include` directive that appears as a direct child of the declaration list.
`isEnclosedInDeclarationList(Cpp.Node.Node child)`	Checks if `child` appears inside a `DeclarationList`.
`getEnclosingDeclarationList(Cpp.Node.Node child, required DeclarationList &parent)`	Finds the nearest enclosing `DeclarationList` ancestor of `child` and returns it as `parent`.
