ValueBase::const_iterator struct reference
[Base module]

Declaration

#include <QtLua/Value>

namespace QtLua {
  class ValueBase {
    struct const_iterator;
  };
};

This struct is a member of the ValueBase class.

Description

This iterator class allow iteration through table like lua values directly from C++ code. Modification of Value object returned by ValueBase::const_iterator::value doesn't modify traversed container.

// code from examples/cpp/value/iterate.cc:40

    // Iterate over lua table from C++ code
    for (QtLua::Value::const_iterator i = table.begin(); i != table.end(); i++)
      qDebug() << i.key().to_string_p()
               << i.value().to_string_p();
