/**
* A KeyAssociation represents a key object that has a natural association
* with another key object. The key object and the associated key may refer
* to entries in the same or different caches.
* 
* For example, the information provided by a key that implements
* KeyAssociation may be used to place the key into the same partition as
* its associated key.
* 
* See {@link com.tangosol.util.filter.KeyAssociatedFilter KeyAssociatedFilter}
* for an example of a distributed query that takes advantage of a custom
* KeyAssociation implementation to dramatically optimize its performance.
