No default value has been defined for property Foo
Abstract Property
MyClass defines the Foo property as Abstract:
classdef MyAbst
properties (Abstract)
Foo
end
end
The meta.property instance for property Foo has a value of false for its HasDefault
property because you cannot define a default value for an Abstract property. Attempting
to access DefaultValue causes an error:
mc = ?MyAbst;
mp = mc.PropertyList(1);
mp.HasDefault
ans =
0
dv = mp.DefaultValue;
Property Foo is abstract and therefore cannot have a default value.
Property with Expression That Errors
MyPropEr defines the Foo property default value as an expression that errors when
evaluated.
classdef MyPropEr
properties
Foo = sin(pie/2)
end
end
