uk.ac.starlink.topcat.plot2
Class ProgressDataStoreFactory

java.lang.Object
  uk.ac.starlink.ttools.plot2.data.WrapperDataStoreFactory
      uk.ac.starlink.topcat.plot2.ProgressDataStoreFactory

All Implemented Interfaces:

uk.ac.starlink.ttools.plot2.data.DataStoreFactory

public class ProgressDataStoreFactory
extends uk.ac.starlink.ttools.plot2.data.WrapperDataStoreFactory

DataStoreFactory wrapper which messages a progress bar model as row data is read from the tables to fill the store. The assumption is that the readDataStore method will only ever be running from one thread at a time; if not, the progress bar updates will get messy.
