Class SeqConcatStarTable

java.lang.Object
uk.ac.starlink.table.WrapperStarTable
uk.ac.starlink.ttools.task.SeqConcatStarTable
All Implemented Interfaces:
Closeable, AutoCloseable, uk.ac.starlink.table.StarTable
public class SeqConcatStarTable extends uk.ac.starlink.table.WrapperStarTable
StarTable implementation which concatenates a list of compatible constituent tables in sequence. Unlike ConcatStarTable it does not attempt to provide random access or to cache tables that it's obtained before. This is particularly suitable for catting an enormous number of tables together.
