public class BreadcrumbsTag

extends WikiTagBase

Implement a "breadcrumb" (most recently visited) trail. This tag can be added to any view jsp page. Separate breadcrumb trails are not tracked across multiple browser windows.
The optional attributes are:

maxpages, the number of pages to store, 10 by default
separator, the separator string to use between pages, " | " by default

This class is implemented by storing a breadcrumb trail, which is a fixed size queue, into a session variable "breadCrumbTrail". This queue is displayed as a series of links separated by a separator character.
