Class SeqConcatStarTable

  • All Implemented Interfaces:
    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.
