DataDistributionManager library.
DataDistributionManager.h contains the public C++ API for DataDistributionManager. The API is documented in this file as comments prefixing the class, function, type, enum, define, etc. The C++ interface is STD C++ '03 compliant and adheres to the Google C++ Style Guide.
| typedef std::map<int64_t, ClusterHealthElement *> ClusterHealth |
Association map between server id and ClusterHealthElement.
| typedef std::map<int64_t,ClusterHealthElement*>::const_iterator ClusterHealthIterator |
