A dynamically typed AST node container.

Stores an AST node in a type safe way. This allows writing code that works with different kinds of AST nodes, despite the fact that they don't have a common base class.

Use create(Node) to create a [DynTypedNode](classclang%5F1%5F1DynTypedNode.html "A dynamically typed AST node container.") from an AST node, and [get<T>()](classclang%5F1%5F1DynTypedNode.html#a5577aae931c4e6d37a8d330190e09ffe "Retrieve the stored node as type T.") to retrieve the node as type T if the types match.

See [ASTNodeKind](classclang%5F1%5F1ASTNodeKind.html "Kind identifier.") for which node base types are currently supported; You can create DynTypedNodes for all nodes in the inheritance hierarchy of the supported base types.

◆ create()

template<typename T >

static DynTypedNode clang::DynTypedNode::create ( const T & Node)	inlinestatic

◆ dump()

void DynTypedNode::dump	(	llvm::raw_ostream &	OS,
const ASTContext &	Context
)	const

◆ get()

template<typename T >

const T * clang::DynTypedNode::get ( ) const	inline

Retrieve the stored node as type T.

Returns NULL if the stored node does not have a type that is convertible to T.

For types that have identity via their pointer in the AST (like [Stmt](classclang%5F1%5F1Stmt.html "Stmt - This represents one statement."), [Decl](classclang%5F1%5F1Decl.html "Decl - This represents one declaration (or definition), e.g."), [Type](classclang%5F1%5F1Type.html "The base class of the type hierarchy.") and [NestedNameSpecifier](classclang%5F1%5F1NestedNameSpecifier.html "Represents a C++ nested name specifier, such as "\::std::vector<int>::".")) the returned pointer points to the referenced AST node. For other types (like [QualType](classclang%5F1%5F1QualType.html "A (possibly-)qualified type.")) the value is stored directly in the [DynTypedNode](classclang%5F1%5F1DynTypedNode.html "A dynamically typed AST node container."), and the returned pointer points at the storage inside DynTypedNode. For those nodes, do not use the pointer outside the scope of the DynTypedNode.
