Default Values

Class definitions can specify explicit default values for properties (see “Property Default

Values” on page 8-18). Determine if a class defines an explicit default value for a property

and what the value of the default is from the property meta.property object.

meta.property Data

The meta.class object for a class contains a meta.property object for every property

defined by the class, including properties with private and protected access.

For example, get the meta.class object for the PropertyWithDefault class shown

here:

classdef PropertyWithDefault

properties

Date = date

RandNumber = randi(9)

end

end

Get an array of meta.property objects from the meta.class object:

mc = ?PropertyWithDefault; % meta.class object

mp = mc.PropertyList; % meta.property array

The second element in the mp array is the meta.property object for the RandNumber

property. Listing the meta.property object shows the information contained in its

properties:

mp(2)
