    • loadDataMapped

      public List<IParticleRecord> loadDataMapped(String file, double factor)
      Description copied from interface: IStarGroupDataProvider
      Loads the data applying a factor using a memory mapped file for improved speed.
      Parameters:
      file - The file to load.
      factor - Factor to apply to the positions.
      Returns:
      The array of particle records.
    • loadDataMapped

      public List<IParticleRecord> loadDataMapped(String file, double factor, int versionHint)
      Loads data mapped with a version hint.
      Parameters:
      file - The file to load
      factor - Distance factor, if any
      versionHint - Data version number, in case of version 0 or 1, since these formats were not annotated. If version >=2, the version number is read from the file header
      Returns:
      The list of particle records.
