java.lang.Object
- uk.ac.starlink.table.join.RowRef

All Implemented Interfaces:

java.lang.Comparable
```
public class RowRef
extends java.lang.Object
implements java.lang.Comparable
```
Represents a reference to a table row. This class really just exists to encapsulate the combination of an int index referencing a table and a long referencing a row of that table. Importantly though, it implements equals, hashCode and the Comparable interface in such a way as to make it suitable for use as keys in a SortedSet. The sort order defined sorts lowest table index first, then lowest row index.
