org.opencms.jsp.CmsJspNavElement

All Implemented Interfaces:

java.lang.Comparable<CmsJspNavElement>

public class CmsJspNavElement
extends java.lang.Object
implements java.lang.Comparable<CmsJspNavElement>

Bean to collect navigation information from a resource in the OpenCms VFS.

Each navigation element contains a number of information about a VFS resource, obtained either from the resources properties or attributes. You can use this information to generate a HTML navigation for files in the VFS in your template.

Note: this class has a natural ordering that is inconsistent with equals.

CmsJspNavElement

public CmsJspNavElement()

Empty constructor required for every JavaBean, does nothing.

Call one of the init methods after you have created an instance of the bean. Instead of using the constructor you should use the static factory methods provided by this class to create navigation beans that are properly initialized with current OpenCms context.
