Detailed Description

template<typename Key, typename T>
class PIMapIteratorConst< Key, T >

Java-style iterator for PIMap.

This class used to easy serial access keys and values in PIMap with read only permitions. Use constructor to create iterator, or use PIMap::makeIterator()

PIMap<int, PIString> m;
m[1] = "one";
m[2] = "two";
m[4] = "four";
auto it = m.makeIterator();
while (it.next()) {
    piCout << it.key() << it.value();
}
// 1 one
// 2 two
// 4 four
