All Implemented Interfaces:

WizardSequence

public class ArraySequence

extends java.lang.Object

implements WizardSequence

Implements a sequence of an array of wizard pages. In general, clients should use one ArraySequence for each group of pages, and compose those sequences together with SequenceSeries objects.

WizardSequences cannot be shared among multiple running wizards, but they can be shared among multiple wizards as long as no two will be running (i.e., visible) at the same time.
