class PackExpansionType
Declaration
class PackExpansionType : public Type, public Node { /* full declaration omitted */ };
Description
Represents a pack expansion of types. Pack expansions are part of C++11 variadic templates. A pack expansion contains a pattern, which itself contains one or more "unexpanded" parameter packs. When instantiated, a pack expansion produces a series of types, each instantiated from the pattern of the expansion, where the Ith instantiation of the pattern uses the Ith arguments bound to each of the unexpanded parameter packs. The pack expansion is considered to "expand" these unexpanded parameter packs. Here, the pack expansion \c Types&... is represented via a PackExpansionType whose pattern is Types & .
