c# - Factory Pattern but with object Parameters -

-

itemprop = "text">

Take the following classic factory patterns: 

  public interface IPizza {decimal value {get; }} Public Square HamAndMushroom Pizza: Ipiza {decimal ipizza.price {get {return 8.5m; }}} Public Intangible Classroom PizzaFactory {Public Abstract IPizza MakePizza (ItalianPizzaFactory.PizzaType pizzaType); } Public class ItalianPizzaFactory: PizzaFactory {public enum PizzaType {HamMushroom, Deluxe, Hawaii} Public Override IPizza MakePizza (PizzaType pizzaType) {Case (PizzaType) {Case: PizzaType.HamMushroom: New HamAndMushroomPizza Return (;); Case pizza type Hawaiian: Return the new Hawaiian Pizza (); Default: New argument throwing exception ("Pizza type" + Pizza type + "Not recognized."); }}}

What if there is a specific requirement for concrete implementation on the creation of a parameter (or several) of concrete pizzas. For example, suppose a parameter called the HamAndMushroom factory, requires MushroomType and would require an illustration of this parameter object?

You can add parameters to the manufacturer method (s) of your factory However, if the number of parameters is more It's getting (this will be more than 2-3 for me), and especially if some or all of the parameters are optional with the proper default values, then you can change the factory in turn. / P>

That is why that can be particularly suitable for pizza, where usually the same layer of topping, is just different (combinations). A builder model is very near the usual way of ordering "Salami, Tomato, Mecca and a Double Paneer Pizza" Otoho may want to define helpful factory methods for "predefined" pizza, e.g.

or createHawaiiPizza which is then built internally using a builder to make a pizza with toppings for that kind of pizza Does.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
