mlreportgen.dom.DebugMessage class

Package: mlreportgen.dom

Creates debugging message text originating from the specified source object.


debugMsgObj = DebugMessage(text,sourceObject) creates a debugging message with the specified text, originating from the specified source object.

Input Arguments

expand all

The text to display for the message.

The DOM object from which the message originates.

Output Arguments

expand all

Debug message, represented by an mlreportgen.dom.DebugMessage object.

ID for this document element, specified as a character vector. The DOM generates a session-unique ID when it creates the document element. You can specify your own ID.

Source DOM object from which the message originates.

Tag for document element, specified as a character vector.

A session-unique ID is generated as part of document element creation. The generated tag has the form CLASS:ID, where CLASS is the class of the element and ID is the value of the Id property of the object. You can specify a tag to replace the generated tag.

For example, to make it easier to identify where an issue occurred during document generation, you can specify your own tag value.

Message text, specified as a character vector.


Use DebugMessage methods similar to how you use ProgressMessage methods.

Create the report document.

import mlreportgen.dom.*;
d = Document('test','html');

Create the listener and add to the message dispatcher.

dispatcher = MessageDispatcher.getTheDispatcher;

dispatcher.Filter.ErrorMessagesPass = true;
dispatcher.Filter.ProgressMessagesPass = false;

l = addlistener(dispatcher,'Message', ...
@(src, evtdata) disp(evtdata.Message.formatAsText));

Create the message and dispatch it before opening.

msg = ErrorMessage('Invalid slide',pre);
dispatch(dispatcher, msg);


Add report content.

p = Paragraph('Chapter ');
p.Tag = 'chapter title';
p.Style = { CounterInc('chapter'),...
    CounterReset('table'),WhiteSpace('pre') };
append(p, AutoNumber('chapter'));

Run report.


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