template<typename CHAR = char, typename TRAITS = std::char_traits<CHAR>>
class pqxx::basic_fieldstream< CHAR, TRAITS >
Input stream that gets its data from a result field.
- Deprecated:
- To convert a field's value string to some other type, e.g. to an
int
, use the field's as<...>()
member function. To read a field efficiently just as a string, use its c_str()
or its as<std::string_vview>()
.
Works like any other istream to read data from a field. It supports all formatting and streaming operations of std::istream
. For convenience there is a fieldstream alias, which defines a basic_fieldstream for char
. This is similar to how e.g. std::ifstream
relates to std::basic_ifstream
.
This class has only been tested for the char type (and its default traits).
