C++ (Cpp) iterator::dup Examples

Example #1

File: plugin.cpp Project: strahlex/libelektra

kdb::KeySet Plugin::getNeededConfig()
{
	Key neededConfigKey ("system/elektra/modules", KEY_END);
	neededConfigKey.addName(pluginName);
	neededConfigKey.addName("config/needs");

	KeySet d (info.dup());
	KeySet config = d.cut(neededConfigKey);

	KeySet ret;
	Key oldParent = neededConfigKey;
	Key newParent("system", KEY_END);
	for (KeySet::iterator i = config.begin(); i != config.end(); ++i)
	{
		Key k(i->dup());
		ret.append(kdb::tools::helper::rebaseKey(k, oldParent, newParent));

	return ret;
