An Integer slot holds an integer number value. (Recall that integer numbers are whole numbers that are positive, negative, or zero; they cannot include a decimal point. Values of type Integer are stored programmatically on your system as integer values.)

To set the value type of a slot to Integer:

  1. Create the slot, or view the Slot Editor for an existing slot.

  2. Select Integer from the Value Type menu.

  3. Fill in the other facets of the slot as desired.

For slots of type Integer, you can enter a Minimum and/or Maximum value.

  • Minimum allows you to specify a minimum value for your slot. When an instance is created for a class with this slot, the value of the slot must be greater than or equal to the minimum. For example, a minimum of zero means instances cannot have negative values.

  • Maximum allows you to specify a maximum value for your slot. When an instance is created for a class with this slot, the value of the slot must be less than or equal to the maximum.

  • Together, Minimum and Maximum can be used to define an allowable range.

When present, the Minimum and/or Maximum values are displayed in the last column of the Template Slots pane.
