 prefuse.data.tuple.TupleManager
| TupleManager | | public class TupleManager (Code) | | Manager class for Tuples. There is a unique Tuple for each row of a table.
All data structures and Tuples are created lazily, on an as-needed basis.
When a row is deleted from the table, it's corresponding Tuple (if created)
is invalidated before being removed from this data structure, ensuring that
any other live references to the Tuple can't be used to corrupt the table.
