Warning Trivial Row

The settings listed below

Default

Strict_warning_default

A trivial row is a row that doesn’t contain any variables but is satisfied, for example: 0 <= 1 .

It takes time to generate and subsequently eliminate such rows. When a significant portion of the rows generated by a symbolic constraint is trivial, the generation of such a constraint seems unduly slow.

What constitutes a significant portion is determined by the option Warning trivial row minimal percentage , but there should be at least hundred trivial rows before this warning is activated.

This option determines how the unnecessary generation of trivial rows should be reported, depending on the following settings:

  • Off

Do not issue a warning.

  • Warning_collect

Issue a warning and post it to the global error and warning collector.

  • Common_warning_default

Take action depending on the option ‘Common warning default’.

  • Warning_handle

Issue a warning and post it to the nearest error handler.

  • Strict_warning_default

Take action depending on the option ‘Strict warning default’.

  • Error

Issue an error.

  • Error_in_develop_else_warning

In a developer system same as Error, in a deployment system same as Warning_handle

  • Error_in_develop_else_off

In a developer system same as Error, in a deployment system same as Off

  • Warning_in_develop_else_off

In a developer system same as Warning_handle, in a deployment system same as Off

Note

  • With the option Maximal Number of Warnings Reported you can set the maximal number of warnings that are shown in errors/warnings and message window.
