Constructor & Destructor Documentation

tip::db::pg::resultset::const_field_iterator::const_field_iterator ( )

inline

Create a terminating iterator

Definition at line 594 of file resultset.hpp.

Member Function Documentation

tip::db::pg::resultset::const_field_iterator::operator bool ( ) const

inline

Implicitly convert to boolean. The row index is valid when it is equal to the row size for an iterator that is returned by end() function to be valid and moveable.
