dynamicprops Class

Superclass for classes that support dynamic properties

Description

dynamicprops is an abstract class that supports dynamic properties. Dynamic properties are used to attach temporary data to MATLAB^® objects. Subclass dynamicprops to define classes that support dynamic properties.

Dynamic properties are associated with a specific object of the class, but are not part of the class definition. Use dynamic properties to attach temporary data to objects. For information on using dynamic properties, see Dynamic Properties — Adding Properties to an Instance.

Note

The isequal function always returns false when comparing objects that have dynamic properties, even if the properties have the same name and value. If you need to compare objects that contain dynamic properties, overload isequal as a method of your class.

The dynamicprops class is a handle class.

Examples

Subclass dynamicprops

Derive a class from the dynamicprops class:

classdef InstanceProperty < dynamicprops
end

Add a property to an object of the class using the addprop method and assign a value to the property.

obj = InstanceProperty;
obj.addprop('NewProperty');
obj.NewProperty = 1:10

obj = 

  InstanceProperty with properties:

    NewProperty: [1 2 3 4 5 6 7 8 9 10]
