[sword-devel] Behavior of SWModule::getConfigEntry in case of multiple entries with same key

[Troy A. Griffitts]

While Peter is correct about how to find all the options that any loaded module might allow for toggling by an end user... and if this is your purpose, you should certainly use the methods Peter suggested... your question as to more generally how to read config entries which have the same key values is answered by how to iterate a multimap in C++. SWModule::getConfig returns the full multimap of config entries. Something like this should work:

ConfigEntMap::const_iterator begin = module->getConfig().lower_bound("Key");
ConfigEntMap::const_iterator end = module->getConfig().upper_bound("Key");

for(; begin !=end; ++begin)  {
  cout << begin->first.c_str() << " = " << begin->second.c_str() << endl;
}

But I've never needed to do this as a client of the library. Maybe if you tell us your use case, we can recommend a facility in the system which might make things easier for you.
