Detailed Description

template<typename ParmDecl, typename ArgType>
class clang::DefaultArgStorage< ParmDecl, ArgType >

Storage for a default argument.

This is conceptually either empty, or an argument value, or a pointer to a previous declaration that had a default argument.

However, this is complicated by modules: while we require all the default arguments for a template to be equivalent, there may be more than one, and we need to track all the originating parameters to determine if the default argument is visible.

Member Function Documentation

clear()

template<typename ParmDecl , typename ArgType >

void clang::DefaultArgStorage< ParmDecl, ArgType >::clear ( )

inline

Remove the default argument, even if it was inherited.

get()

template<typename ParmDecl , typename ArgType >

ArgType clang::DefaultArgStorage< ParmDecl, ArgType >::get ( ) const

inline

Get the default argument's value.

This does not consider whether the default argument is visible.

getInheritedFrom()

template<typename ParmDecl , typename ArgType >

const ParmDecl * clang::DefaultArgStorage< ParmDecl, ArgType >::getInheritedFrom ( ) const

inline

Get the parameter from which we inherit the default argument, if any.

This is the parameter on which the default argument was actually written.
