The following illustration shows a typical property specification.
delineate a block of code that defines properties having the same
Note: Properties cannot have the same name as the class.
For an example, see Create a Simple Class.
The preceding example shows the
specified as having a default value of
[0 0 1].
You can initialize property values with MATLAB® expressions. However, these expressions cannot refer to the class that you are defining in any way, except to call class static methods. MATLAB executes expressions that create initial property values only when initializing the class, which occurs just before first using the class. See Property Default Values for more information about how MATLAB evaluates default value expressions.
Property names must be listed on separate lines. MATLAB interprets a name following a property name as the name of a class.
You can restrict property values by associating a class with
the property in the property definition. For example, the definition
MyData requires that values assigned to this
property must be of type
int32 or types that are
properties MyData int32 end
For more information, see Validate Property Values.
Property access syntax is like MATLAB structure field syntax.
For example, if
obj is an object of a class, then
you can get the value of a property by referencing the property name:
val = obj.PropertyName
Assign values to properties by putting the property reference on the left side of the equal sign:
obj.PropertyName = val
When you access a property, MATLAB executes any property set or get access method and triggering any enabled property events.
When you derive one class from another class, the derived (subclass) class inherits all the properties of the superclass. In general, subclasses define only properties that are unique to that particular class. Superclasses define properties that more than one subclass use.
Attributes specified with the
apply to all property definitions that follow in that block. If you
want to apply attribute settings to certain properties only, reuse
properties keyword and create another property
block for those properties.
For example, the following code shows the
private for the
but not for the
