Value class reference
[Base module]

Declaration  

#include <QtLua/Value>

namespace QtLua {
class Value;
};

This class is a member of the QtLua namespace.

Description  

This class exposes a lua value to C++ code. It provides conversion functions, cast operators, access operators and standard C++ iterators.

Each Value object store its associated lua value in the lua interpreter state registry table.

See also Qt/Lua types conversion section, Iterator class, ValueBase::iterator struct and ValueBase::const_iterator struct.
