public class MapLikeType
Type that represents Map-like types; things that consist of key/value pairs but that
do not necessarily implement Map, but that do not have enough
introspection functionality to allow for some level of generic handling.
This specifically allows framework to check for configuration and annotation
settings used for Map types, and pass these to custom handlers that may be more
familiar with actual type.
| Field Summary | |

_keyType
Type of keys of Map. |
