                  throws java.io.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

                  throws java.io.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:
        java.io.IOException
