RandomStarTable (Starjava Table API)

java.lang.Object
- uk.ac.starlink.table.AbstractStarTable
- - uk.ac.starlink.table.RandomStarTable

All Implemented Interfaces:

StarTable

Direct Known Subclasses:

BeanStarTable, ColumnStarTable, ConstantStarTable, RandomResultSetStarTable, RowListStarTable
```
public abstract class RandomStarTable
extends AbstractStarTable
```
Implements a StarTable based on random access. The isRandom method always returns true, and the getRowSequence method is implemented using the table's (abstract) getCell and getRow methods.
Implementations of this object must supply a non-negative return value for getColumnCount method, because the RowSequence method requires this knowledge.
