Function Documentation

◆ dropDefaultArgs()

static CallExpr::arg_range dropDefaultArgs ( CallExpr::arg_range  Args)

Definition at line 158 of file BuildTree.cpp.

◆ getDeclaratorRange()

static SourceRange getDeclaratorRange ( const SourceManager SM,
TypeLoc  T,
SourceLocation  Name,
SourceRange  Initializer 

Gets the range of declarator as defined by the C++ grammar.

E.g. int a; -> range of a, int *a; -> range of *a, int a[10]; -> range of a[10], int a[1][2][3]; -> range of a[1][2][3], int *a = nullptr -> range of *a = nullptr. int S::f(){} -> range of S::f(). FIXME: Name must be a source range.

Definition at line 292 of file BuildTree.cpp.

References clang::Initializer, clang::SourceLocation::isInvalid(), SM, and clang::T.

◆ getInitializerRange()

static SourceRange getInitializerRange ( Decl D)

Gets the range of the initializer inside an init-declarator C++ [dcl.decl].

int a; -> range of `, int *a = nullptr-> range of= nullptr. int a{}-> range of{}. int a()-> range of()`.

Definition at line 273 of file BuildTree.cpp.

◆ getOperatorNodeKind()

static syntax::NodeKind getOperatorNodeKind ( const CXXOperatorCallExpr E)

◆ getQualifiedNameStart()

static SourceLocation getQualifiedNameStart ( NamedDecl D)

Get the start of the qualified name.

In the examples below it gives the location of the ^: int ^a; int *^a; int ^a::S::f(){}
