VarTemplateDecl * VarDecl::getDescribedVarTemplate ( ) const

Retrieves the variable template that is described by this variable declaration.

Every variable template is represented as a VarTemplateDecl and a VarDecl. The former contains template properties (such as the template parameter lists) while the latter contains the actual description of the template's contents. VarTemplateDecl::getTemplatedDecl() retrieves the VarDecl that from a VarTemplateDecl, while getDescribedVarTemplate() retrieves the VarTemplateDecl from a VarDecl.

InitializationStyle clang::VarDecl::getInitStyle ( ) const
inline

The style of initialization for this declaration.

C-style initialization is "int x = 1;". Call-style initialization is a C++98 direct-initializer, e.g. "int x(1);". The Init expression will be the expression inside the parens or a "ClassType(a,b,c)" class constructor expression for class types. List-style initialization is C++11 syntax, e.g. "int x{1};". Clients can distinguish between different forms of initialization by checking this value. In particular, "int x = {1};" is C-style, "int x({1})" is call-style, and "int x{1};" is list-style; the Init expression in all three cases is an InitListExpr.

bool clang::VarDecl::isNRVOVariable ( ) const
inline

Determine whether this local variable can be used with the named return value optimization (NRVO).

The named return value optimization (NRVO) works by marking certain non-volatile local variables of class type as NRVO objects. These locals can be allocated within the return slot of their containing function, in which case there is no need to copy the object to the return slot when returning from the function. Within the function body, each return that returns the NRVO object will have this variable as its NRVO candidate.
