Function Documentation

template<typename T> PGSTD::string Classname (  const T *    )

Return user-readable name for a class. Specialize this whereever used.

template<> PGSTD::string Classname (  const TableStream *    )

template<> PGSTD::string Classname (  const TransactionItf *    )

Human-readable class names for use by Unique template.

template<> const char* FmtString (  char    )

template<> const char* FmtString (  double    )

template<> const char* FmtString (  float    )

template<> const char * pqxx::FmtString (  unsigned    char )

template<> const char * pqxx::FmtString (  long    double )

template<> const char* FmtString (  int    )

template<typename T> const char* FmtString (  T    )

C-style format strings for various built-in types. Only allowed for certain types, for which this function is explicitly specialized below.

template<> void FromString (  const char    Str[], bool &    Obj )

template<> void FromString (  const char    Str[], const char *&    Obj )

template<> void FromString (  const char    Str[], PGSTD::string &    Obj )

template<typename T> void FromString (  const char    Str[], T &    Obj )

Result::const_iterator operator+ (  Result::const_iterator::difference_type    o, Result::const_iterator    i )

template<> PGSTD::string Quote (  const char *const &    Obj, bool    EmptyIsNull )

In the special case of const char *, the null pointer is represented as the null value.

template<> PGSTD::string Quote (  const PGSTD::string &    Obj, bool    EmptyIsNull )

std::string version, on which the other versions are built

template<typename T> PGSTD::string pqxx::Quote (  const T &    Obj, bool    EmptyIsNull = false )

Generate SQL-quoted version of string. If EmptyIsNull is set, an empty string will generate the null value rather than an empty string.

template<> PGSTD::string ToString (  const unsigned short &    Obj )

template<> PGSTD::string ToString (  const short &    Obj )

template<> PGSTD::string ToString (  const bool &    Obj )

template<> PGSTD::string ToString (  const char *const &    Obj )

template<> PGSTD::string ToString (  const PGSTD::string &    Obj )

template<typename T> PGSTD::string ToString (  const T &    Obj )

Convert object of built-in type to string.
