This inspection reports any classes with no toString() method.

This inspection will use the exclude settings from the plugin configuration to ignore classes having fields not supposed to be dumped.
An additional settings is to exclude certain classes by using a regular expression matching the classname.
Exception, deprecated, abstract or enum classes can also be excluded.

This inspection can use on-the-fly code inspection by enabling it to show errors as warnings. This will highlight the classname on-the-fly in the java editor.

Notice 'on-the-fly' should be enabled from the settings to this plugin.
