Class SequenceList

java.lang.Object
  com.itextpdf.text.pdf.SequenceList

public class SequenceList
extends Object

This class expands a string into a list of numbers. The main use is to select a range of pages.

The general syntax is:
[!][o][odd][e][even]start-end

You can have multiple ranges separated by commas ','. The '!' modifier removes the range from what is already selected. The range changes are incremental, that is, numbers are added or deleted as the range appears. The start or the end, but not both, can be omitted.
