• How to do method chaining in Java? o.m1().m2().m3().m4()

  - by Pentium10

  Maybe the title might be better, if someone knows a better one, please edit. I've seen in many Java code notation that after a method we call another, here is an example. Toast.makeText(text).setGravity(Gravity.TOP, 0, 0).setView(layout).show(); As you see after calling makeText on the return we call setGravity and so far. How can I do this with my own classes? Do I have to do anything special?

• In Ruby, how to write a method to display any object's instance variable names and its values

  - by Jian Lin

  Given any object in Ruby (on Rails), how can I write a method so that it will display that object's instance variable names and its values, like this: @x: 1 @y: 2 @link_to_point: #<Point:0x10031b298 @y=20, @x=38> I also want to be able to print <br> to the end of each instance variable's value so as to print them out nicely on a webpage. the difficulty now seems to be that not every instance variable has an accessor, so it can't be called with obj.send(var_name) (the var_name has the "@" removed, so "@x" becomes "x")

• what is the required code method of making a sticker app?

  - by zeropt7

  I am new to photo apps, recently I am interested in making a sticker app like those can be seen in the appstore, I know I would need to use uiimagepickercontroller, uiscrollview and uigesturerecognizer. However I wonder which code method should I use for the app to load multiple stickers? Should it be called programmatically? Is that I would need to use the if-statement, say if one sticker is loaded, the app will auto generate a new sticker on top of it?

• Is passing a struct value to a method by-reference in C# an acceptable optimization?

  - by Arc

  Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?

• C# Why does code compile fine when there is an ambiguous virtual method?

  - by Jimbo

  I have a class (Class B) that inherits another class (Class A) that contains virtual methods.
