class FunctionParmPackExpr

Declaration

class FunctionParmPackExpr : public Expr, private TrailingObjects { /* full declaration omitted */ };

Description

Represents a reference to a function parameter pack or init-capture pack that has been substituted but not yet expanded. When a pack expansion contains multiple parameter packs at different levels, this node is used to represent a function parameter pack at an outer level which we have already substituted to refer to expanded parameters, but where the containing pack expansion cannot yet be expanded.

Declared at: clang/include/clang/AST/ExprCXX.h:4397

Member Variables

private clang::VarDecl* ParamPack

The function parameter pack which was referenced.

private clang::SourceLocation NameLoc

private unsigned int NumParameters
