class PackExpansionExpr
Declaration
class PackExpansionExpr : public Expr { /* full declaration omitted */ };
Description
Represents a C++11 pack expansion that produces a sequence of expressions. A pack expansion expression contains a pattern (which itself is an expression) followed by an ellipsis. For example: Here, the argument to the function object \c f is a pack expansion whose pattern is \c static_cast<Types&&>(args). When the \c forward function template is instantiated, the pack expansion will instantiate to zero or or more function arguments to the function object \c f.
