IlvMapServlet
provides support
for client-side image maps. The image map can be used to attach actions
to every node or link displayed in the diagram. IlvMapServlet
extends IlvDiagrammerServlet, it uses the same protocols as IlvManagerServlet to
communicate with clients. IlvMapServlet
is
also subclass of IlvSDMServlet and
inherits its session capabilities. Depending on the value of the multiSession
configuration
parameter, the servlet can work in either mono-session
or multi-session mode. By default, the servlet runs in mono-session
mode. See Mono-session and multi-session modes for
more information.Name |
Description |
---|---|
Mono-session |
If multiSession is
set to false , one SDM engine and one SDM
view, including one grapher, are created. All the requests to the
servlet return an image of the same shared diagram. This option is
appropriate if the users are not allowed to modify the contents of
the diagram or if the changes should be visible by all users. |
Multi-session |
If multiSession is
set to true , a new SDM engine, and its
associated SDM view and grapher, is created for every different client
session connected to the servlet. This mode is appropriate if users
are allowed to modify the XML file or the style sheet. |
