Member Function Documentation

internal::Arg fmt::ArgList::operator[] ( unsigned  index ) const

inline

Returns the argument at specified index.

 {
 using internal::Arg;
 Arg arg;
 bool use_values = type(MAX_PACKED_ARGS - 1) == Arg::NONE;
 if (index < MAX_PACKED_ARGS) {
 Arg::Type arg_type = type(index);
 internal::Value &val = arg;
 if (arg_type != Arg::NONE)
 val = use_values ? values_[index] : args_[index];
 arg.type = arg_type;
 return arg;
 }
 if (use_values) {
 // The index is greater than the number of arguments that can be stored
 // in values, so return a "none" argument.
 arg.type = Arg::NONE;
 return arg;
 }
 for (unsigned i = MAX_PACKED_ARGS; i <= index; ++i) {
 if (args_[i].type == Arg::NONE)
 return args_[i];
 }
 return args_[index];
 }
