When an instance is created for a class with a slot of Value Type Integer, the entry field corresponding to the slot is an Integer entry field, taking whole numbers as values.

Single Cardinality

The entry field corresponding to a slot of value type Integer with Cardinality Single can contain a single integer number. It appears as an entry bar:

  • To edit a value, click in the entry field and make your edits.

  • To create a value, enter a whole number in the entry field.

  • To clear a value, delete the value in the entry field.

Error Detection

The information in a Integer field must be a whole number. If you enter text or other invalid information, such as values less than the minimum or greater than the maximum, the entered value will be displayed in red and will not be saved by the system. The previous value (if any) will be used instead. The following example shows such an invalid entry ("four") in an Integer field:

Multiple Cardinality

The entry field corresponding to a slot of type Integer with Cardinality Multiple shows a display list with three buttons. This field takes a list of integer values. If the at most value is set in the Cardinality field for the slot, there is a limit on the number of values you can enter.
