Interface TableSequence

All Known Implementing Classes:

QueueTableSequence

public interface TableSequence

Iterator over tables. Unlike the java.util.Iterator interface, the nextTable method throws a checked exception.

A suitable looping idiom is

     TableSequence tseq = getTableSequence();
     for (StarTable table; (table = tseq.nextTable()) != null;) {
         doStuff(table);
     }
