In this case, list is the name of the package, which you are importing via import “container/list”, and its public members are upper case, like List. The rule is that public functions, types, etc., should be upper case. You can alias imported packages however you want, but by default it is just the name of … Read more
Only call time pass-by-reference is removed. So change: call_user_func($func, &$this, &$client … To this: call_user_func($func, $this, $client … &$this should never be needed after PHP4 anyway period. If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)
Don’t use a field – use a property: class Foo { public string Bar { get; private set; } } In this example Foo.Bar is readable everywhere and writable only by members of Foo itself. As a side note, this example is using a C# feature introduced in version 3 called automatically implemented properties. This … Read more
In order for an item to be exported from a library crate, there must be at least one path leading to it in which every component is public. This means that all you need to make an item public within your crate but not exported from the crate (I’ll call this “internal” from now on, … Read more
The closest thing (not exactly the same, final has other meanings too) for Java final fields I can think of is readonly: public static readonly MyClass field = new MyClass(“foo”); If you have a primitive type (string, int, boolean), you may want to use const instead. public const string MAGIC_STRING = “Foo”;
There’s one reason to not use a constant directly in your code. Assume FOO may change later on (but still stay constant), say to public static final int FOO = 10;. Shouldn’t break anything as long as nobody’s stupid enough to hardcode the value directly right? No. The Java compiler will inline constants such as … Read more
.NET has spoiled us 🙂 Your declaration is not valid for VBA. Only constants can be given a value upon application load. You declare them like so: Public Const APOSTROPHE_KEYCODE = 222 Here’s a sample declaration from one of my vba projects: If you’re looking for something where you declare a public variable and then … Read more
Without specifying public the class is implicitly internal. This means that the class is only visible inside the same assembly. When you specify public, the class is visible outside the assembly. It is also allowed to specify the internal modifier explicitly: internal class Foo {}
What I have seen someday on SO, as answer (written by @ChssPly76) why to use getters and setters Because 2 weeks (months, years) from now when you realize that your setter needs to do more than just set the value, you’ll also realize that the property has been used directly in 238 other classes 🙂 … Read more
