Pump with properties:

Speed: Medium

The numerical value is available from the property.

getGPM(p)

Flow rate is: 50 GPM

Integer Class Validation

MATLAB supports several integer classes (see “Integers”). However, restricting a

property to an integer class can result in integer overflow. The resulting value can

saturate at the maximum or minimum value in the integer’s range.

When integer overflow occurs, the value that is assigned to a property might not be the

value from the right side of the assignment statement.

For example, suppose that you want to restrict a property value to a scalar uint8.

classdef IntProperty

properties

Value(1,1) uint8

end

end

Assigning a numeric value to the Value property effectively casts the numeric value to

uint8, but does not result in an error for out-of-range values.

a = IntProperty;

a.Value = -10;

disp(a.Value)

0
