Examples of com.hazelcast.core.MultiMap

com.hazelcast.core.MultiMap
A specialized map whose keys can be associated with multiple values.

Gotchas:
- Methods, including but not limited to get, containsKey, containsValue, remove, put, lock, unlock, do not use hashCode and equals implementations of keys, instead they use hashCode and equals of binary (serialized) forms of the objects.
- Methods, including but not limited to get, remove, keySet, values, entrySet, return a collection clone of the values. The collection is NOT backed by the map, so changes to the map are NOT reflected in the collection, and vice-versa.
