Interface ReferenceCache

All Known Implementing Classes:
NoopReferenceCache
public interface ReferenceCache
The simple interface needed to battle object proliferation when many objects of a type with low cardinality are created. The idea is that you still create the object, but rather than hanging on to it, you pass it through the cache, which may replace your object with a reference to a previously-created object.
