Detailed Description

FriendDecl - Represents the declaration of a friend entity, which can be a function, a type, or a templated function or type.

 template <typename T> class A {
   friend int foo(T);
   friend class B;
   friend T; // only in C++0x
   template <typename U> friend class C;
   template <typename U> friend A& operator+=(A&, const U&) { ... }
 };

The semantic context of a friend decl is its declaring class.

NamedDecl* clang::FriendDecl::getFriendDecl ( ) const [inline]

If this friend declaration doesn't name a type, return the inner declaration.

Definition at line 126 of file DeclFriend.h.

Referenced by getSourceRange(), MatchesFriend(), and clang::ASTDeclWriter::VisitFriendDecl().

SourceLocation clang::FriendDecl::getFriendLoc ( ) const [inline]

Retrieves the location of the 'friend' keyword.

Definition at line 131 of file DeclFriend.h.

Referenced by getSourceRange().

TypeSourceInfo* clang::FriendDecl::getFriendType ( ) const [inline]

If this friend declaration names an (untemplated but possibly dependent) type, return the type; otherwise return null. This is used for elaborated-type-specifiers and, in C++0x, for arbitrary friend type declarations.
