Namespace: mlreportgen.dom

DOM message dispatcher

Description

Dispatcher for document generation status messages.

Note

When you create a message dispatcher, the DOM API keeps the dispatcher until the end of the current MATLAB® session. Delete message event listeners to avoid duplicate reporting of message objects during a MATLAB session.

The mlreportgen.dom.MessageDispatcher class is a handle class.

Properties

(Read-only) The value of this property is a filter that determines the types of messages the dispatcher dispatches. You can control which types of messages are dispatched by setting the properties of the filter.

Object identifier for the mlreportgen.dom.MessageDispatcher object, specified as a character vector or string scalar. The DOM API generates a session-unique identifier when it creates the document element object. You can specify your own value for Id.

Attributes:

NonCopyable
true

Data Types: char | string

Tag for the mlreportgen.dom.MessageDispatcher object, specified as a character vector or string scalar. The DOM API generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Specify your own tag value to help you identify where to look when an issue occurs during document generation.

This example shows how to add a progress message to display when generating a report.

Add a dispatcher and listener to the report.

import mlreportgen.dom.*;
doctype = 'html';
d = Document('test',doctype);
d.Tag = 'My report';
          dispatcher = MessageDispatcher.getTheDispatcher;
l = addlistener(dispatcher,'Message', ...
    @(src,evtdata) disp(evtdata.Message.formatAsText));
     
open(d);
dispatch(dispatcher,ProgressMessage('starting chapter',d));
p = Paragraph('Chapter ');
p.Tag = 'chapter title';
append(d,p);
     
close(d);
rptview('test',doctype);

Delete the listener to avoid duplicate reporting of message objects during a MATLAB session.

delete(l);

Check the progress messages in the MATLAB Command Window. The starting chapter message appears, in addition to the predefined DOM progress messages.
