Syntax for Importing Classes

Import classes into a function to simplify access to class members. For example, suppose

that there is a package that contains several classes and you need to use only one of these

classes in your function, or even just a static method from that class. Use the import

command to simplify code. Once you have imported the class, you do not need to

reference the package name:

function myFunc

import pkg.cls1

obj = cls1(arg,...); % call cls1 constructor

obj.Prop = cls1.staticMethod(arg,...); % call cls1 static method

end

Import all classes in a package using the syntax pkg.*:

function myFunc

import pkg.*

obj1 = cls1(arg,...); % call pkg.cls1 constructor

obj2 = cls2(arg,...); % call pkg.cls2 constructor

a = pkgFunction(); % call package function named pkgFunction

end

Import Package Functions

Use import to import package functions:

function myFunc

import pkg.pkfcn

pkfcn(arg,...); % call imported package function

end
