      public ReplaceValueTable(uk.ac.starlink.table.StarTable baseTable, boolean[] colFlags, String oldStr, String newStr) throws IOException
      Constructs a new ReplaceValueTable with the same replacement taking place in zero or more of the base table's columns, as described by an array of flags.
      Parameters:
      baseTable - base table
      colFlags - array of flags for each column of the table, true only for those columns which should be modified
      oldStr - value to be replaced
      newStr - replacement value
      Throws:

    • ReplaceValueTable

      public ReplaceValueTable(uk.ac.starlink.table.StarTable baseTable, int[] icols, String[] oldStrs, String[] newStrs) throws IOException
      Constructs a new ReplaceValueTable from parallel arrays describing the columns to change and the old and new values. The additional arguments are a set of parallel arrays, with an element for each of the replacements which will happen. Each of the arrays icols, oldStrs and newStrs must have the same number of elements. Indices in icols ought not to be repeated.
      Parameters:
      baseTable - base table
      icols - array of column indices in which replacements will occur
      oldStrs - array of strings to be replaced, one for each of the columns in icols
      newStrs - array of strings to furnish replacement values, one for each of the columns in icols
      Throws:
      IOException
