| org.openrdf.sail.memory.model.WeakObjectRegistry
| WeakObjectRegistry | | public class WeakObjectRegistry extends AbstractSet (Code) | | An object registry that uses weak references to keep track of the stored
objects. The registry can be used to retrieve stored objects using another,
equivalent object. As such, it can be used to prevent the use of duplicates
in another data structure, reducing memory usage. The objects that are being
stored should properly implement the
Object.equals and
Object.hashCode methods.
