Methods Summary
public java.lang.Objectclone()

      DeltaRecord rec = new DeltaRecord();
      rec.field_1_max_change = field_1_max_change;

protected voidfillFields(org.apache.poi.hssf.record.RecordInputStream in)

        field_1_max_change = in.readDouble();
    
public doublegetMaxChange()
get the maximum change

return
maxChange - maximum rounding error

        return field_1_max_change;
    
public intgetRecordSize()

        return 12;
    
public shortgetSid()

        LittleEndian.putDouble(data, 4 + offset, getMaxChange());
        return getRecordSize();
    
public voidsetMaxChange(double maxChange)
set the maximum change

param
maxChange - maximum rounding error

        field_1_max_change = maxChange;
