Defines the clang::ASTContext interface.
A (possibly-)qualified type.
void print(raw_ostream &OS, const PrintingPolicy &Policy, const Twine &PlaceHolder=Twine(), unsigned Indentation=0) const
static ASTNodeKind getFromNode(const Decl &D)
Construct an identifier for the dynamic type of the node.
Stmt - This represents one statement.
StringRef asStringRef() const
String representation of the kind.
Decl - This represents one declaration (or definition), e.g.
The base class of the type hierarchy.
Describes how types, statements, expressions, and declarations should be printed. ...
Base wrapper for a particular "section" of type source info.
A C++ nested-name-specifier augmented with source location information.
ASTNodeKind()
Empty identifier. It matches nothing.
void dump(llvm::raw_ostream &OS, SourceManager &SM) const
Dumps the node to the given output stream.
const FunctionProtoType * T
Represents a C++ template name within the type system.
static ASTNodeKind getMostDerivedType(ASTNodeKind Kind1, ASTNodeKind Kind2)
Return the most derived type between Kind1 and Kind2.
SourceRange getSourceRange() const
For nodes which represent textual entities in the source code, return their SourceRange.
Represents a C++ nested name specifier, such as "\::std::vector<int>::".
TypeClass getTypeClass() const
bool isBaseOf(ASTNodeKind Other, unsigned *Distance=nullptr) const
Returns true if this is a base kind of (or same as) Other.
Represents a template argument.
static ASTNodeKind getMostDerivedCommonAncestor(ASTNodeKind Kind1, ASTNodeKind Kind2)
Return the most derived common ancestor between Kind1 and Kind2.
Dataflow Directional Tag Classes.
StmtClass getStmtClass() const
Represents a C++ base or member initializer.
Defines the C++ Decl subclasses, other than those for templates (found in DeclTemplate.h) and friends (in DeclFriend.h).
A trivial tuple used to represent a source range.
This class handles loading and caching of source files into memory.
void print(llvm::raw_ostream &OS, const PrintingPolicy &PP) const
Prints the node to the given output stream.
