java - Builder pattern vs. config object -


Builder patterns are popular for creating irreversible objects, but there are some programming overheads to make a builder so I wonder Why not just use a config object?

The use of a builder will appear as: 

  product page = product. Name ("vodka"). Alcohol (0.38) .size (0.7) .price (17.99) .build (); It is clear that it is very readable and concise, but you have to implement the builder:  
  public class product {the name of the public final string; Public last float alcohol; Public last float size; Public last float price; Personal Product (Builder Builder) {this.name = builder.name; this. Alcohol = Builder alcohol; This.size = builder.size; this. Value = builder value; } Public Static Class Builder {Name of Private String; Private Float Alcohol; Private float size; Private float price; // Mandatory Public Static Builder Name (String Name) {Builder B = New Builder (); B.name = name; Return b; } Public Builder Alcohol (Float Alcohol) {this.alcohol = alcohol; Return.this; } Size of the public builder (float size) {this.size = size; Return.this; } Public Builder Price (Float Price) {this.price = price; Return.this; } Public product creation () {Return new product (this); }}}  
 
 I think, to reduce the code by using a simple config object like this: 
 
  class ProductConfig {public string name of the; Public float alcohol; Public float size; Price of public float; // name still mandatory public productConfig (string name) {this.name = name; }} Public class product {the name of the public final string; Public last float alcohol; Public last float size; Public last float price; Public product (ProductConfig config) {this.name = config.name; this. Alcohol = config.alcohol; This.size = config.size; This.price = config.price; }}  
 
 Usage: 
 
  ProductConfig config = New ProductConfig ("vodka"); Config.alcohol = 0.38; Config.size = 0.7; Config.price = 17.99; Product p = new product (config);  
 
 This usage needs some more lines but it is very readable, but the implementation is very easy and it is probably easy to understand for the person who is not familiar with the builder pattern. By the way: is there a name for this method? 
 
 What is ignored in the config application that I have ignored?
post builder pattern decoupling improvements - if your product is an interface and builder only the orbit that can be aware of implementation (or implementation, in some cases) The builder also applies an interface so you can inject it into your code so that you can increase the decoupling further.

This decoupling means that your code is more compact and easy to test

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....

Message box window Public partial class custom message box: window {public representative message messagebox object sender, event events e); Public event messagebox handler messagebox document; Public Customs Box () {Initial group (); } Public Customsbox (String Message) {InitializeComponent (); This.txtdescription.Text = Message; } Public Customsbox (String Message, String Title, String First BTNtext) {Initialization (); This.lbltitle.Content =...
