method-chaining

In .Net, you can chain methods returning a value or by using a void. Is one of them the "right way"? So you could say 1) Foo myFoo = new Foo(); myfoo.Bars = myBars.DoSomethingCool(x) .DoSomethingElse(y) .AndSomethingElse(z); public static IList<IBar> DoSomethingCool(this IList<IBar> source, object x) { IList<IBar> result = //some fn(source) return result; } In this case, all 3 extension methods need to return IList (the type for myFoo.Bars) or it could also be written as 2) myBars.DoSomethingCool(x) .DoSomethingElse(y) .AndSomethingElse(z); public static void DoSomethingCool(this IList<IBar>

Is it possible to know if a method call is from a method chaining? For example, I have the bellow class : class Test{ protected $string = '123'; public function a($string){ $this->string .= $string; if(method chain){ return $this; }else{ return $this->string; } } public function b($string){ $this->string .= $string; if(method chain){ return $this; }else{ return $this->string; } } } Result: $test = new Test(); echo $test->a('000'); // 123000 echo $test->a('000')->b('www'); // 123000www UPDATE I ended up creating an exec() method to tell no more methods were going to be called. public function

Actaully my application is having hundreds of pages. Now i have to attach an event 'disablePage' on onSubmit of form. I don't want to go to each and every page and write: <form name="frmname" onSubmit="disablePage();"> What i am doing right now is:- excerpt from common.js file; [ included in all pages ] /* we have to attach 'attachFormSubmit' method on onLoad event, otherwise forms[0] will always be null. If there is any alternative, then please suggest one */ if (window.addEventListener){ window.addEventListener('load', attachFormSubmit, false); } else if (window.attachEvent){ window

I have a chain call like so: $object->getUser()->getName(); I know that I can use a string to call a function on an object: $functionName = 'getUser'; $object->$functionName() or call_user_func(array($object, functionName)) I was wondering if it was possible to do the same for a chain call? I tried to do: $functionName = 'getUser()->getName'; $object->functionName(); But I get an error Method name must be a string I guess this is because the () and -> cannot be interpreted since they are part of a string? Is there any way I can achieve this without having to do: $function1 = getUser;

In StringBuilder class I can do like this: StringBuilder sb = new StringBuilder(); sb.append( "asd").append(34); method append returns StringBuilder instance, and I can continuosly call that. My question is it possible to do so in static method context? without class instance Yes. Like this (untested). public class Static { private final static Static INSTANCE = new Static(); public static Static doStuff(...) { ...; return INSTANCE; } public static Static doOtherStuff() { .... return INSTANCE; } } You can now have code like. Static.doStuff(...).doOtherStuff(...).doStuff(...); I would recommend

How do you write new chained methods in jQuery? I have a very procedural style in my jQuery: $("#SaveButton").click(function () { Foo($("#SubTotal")); Foo($("#TaxTotal")); Foo($("#Total")); Bar($("#SubTotal")); Bar($("#TaxTotal")); Bar($("#Total")); }); How do I create a .foo() method in jQuery so that I can then write: $("#SaveButton").click(function () { $("#SubTotal,#TaxTotal,#Total").foo().bar(); }); And in a related point - is there an easy way (in Visual Studio, or Notepad++ or something else) to find and replace all Foo($("#selector")); with $("#selector").foo(); ? You can define custom
