Everything about Type is reflective in nature. Is it because Type is used more often than the rest of the classes in System.Reflection? Or because it functions more like a system class than a reflection class?
In short, I've always wondered what the motivation behind the location of System.Type was.
Assume I have a generic type P which is an Enum, that is <P extends Enum<P>>, and I want to get the Enum value from a string, for example:
String foo = "foo";
P fooEnum = Enum.valueOf(P.class, foo);
This will get a compile error because P.class is invalid. So what can I do in order to make the above code work?
I'm having some strange issues with .removeClass() and .addClass() in jQuery.
Specifically it seems that when I use .removeClass() the class is indeed removed, but a single space is left in it's place. then when I .addClass("secondclass") I get class=" secondclass" (with the space in front).
I'm using jQuery 1.4.1
Is this intended behaviour or a bug? How to stop it?
I have a MyServer class that contains a Map whose keys are MyClientType objects and whose values are MyClient objects. I'd like to depict this relationship in a class diagram but I can't figure out a clean way to do that.
I'm calling the twitter4j library using Clojure like so:
(def twitter (. (TwitterFactory.) getInstance))
This works fine when I call it as a script. But when I use gen-class, I get:
java.lang.IllegalArgumentException: Can't call public method of non-public class: public java.lang.Object twitter4j.TwitterFactoryBase.getInstance()
Is there a workaround for this?
I want a link that scrolls the page to the start of the <div class="content-body">
The same functionality as a: <a href="#maincontent">Skip</a>, and placing <a name="maincontent"></a> right next to <div class="content-body">
I am seeing if it is possible via jQuery, and want to know if I would run into any problems down the road using that method (besides the user having javascript disabled).
1) Why are member constants available even if there are no instances of a its class?
2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value?
3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why?
class A
{
const string b = “it works”;
}
thank you
Is it possible to pickle an object from a class with slots, when this object references itself through one of its attributes? Here is a simple example:
import weakref
import pickle
class my_class(object):
__slots__ = ('an_int', 'ref_to_self', '__weakref__')
def __init__(self):
self.an_int = 42
self.ref_to_self = weakref.WeakKeyDictionary({self: 1})
# __getstate__ and __setstate__ not defined: how should this be done?
if __name__ == '__main__':
obj = my_class()
# How to make the following work?
obj_pickled = pickle.dumps(obj)
obj_unpickled = pickle.loads(obj_pickled)
# Self-references should be kept:
print "OK?", obj_unpickled == obj_unpickled.ref_to_self.keys()[0]
Hi, I've been trying to make a button toggle a class, as well as show another div below it.
Here is a jsFiddle example I have made for you.
The first function works perfectly, shows and hides the div, but also I want the button itself to add and remove a class, I thought this would work but I seem to be doing something wrong.
Thanks.
I want the class to auto-attach its required css and js files when instantiated...
is there any way of a class knowing where it is (and its files) in relation to the root?
if 1 is possible, is there a way to check if a css/js file has already been referenced in the file, or is this not necessary(do browsers ignore duplicate css/js file references)?
How can I format all td elements contained in a table with class myclass in CSS?
I want a format rule which applies to <table class="myclass"><td>FORMAT THIS</td></table>.
I am trying to do the following in a bit of python code:
class Parent:
class Child(Parent):
pass
And it does not work. Is there any python syntax I can use to achieve the same result?
Thanks.
I am trying to set the class for an intent to the address listed in a string value, so that I can launch a given activity. The string is composed dynamically during runtime.
Is there anyway to make something like the code below run:
String target=com.test.activity1.class;
Intent intent=new intent();
intent.setClass(this, target);
Thanks
What is the difference when a class extend from Handler and Thread?
As described in developer.android.com
...
Each Handler instance is associated with a single thread and that thread's message queue.
...
Does the thread has no message queue ?
Any benefit for a class extend from Handler?
Welcome,
It it possible to select all checkboxes / uncheck all checkboxes what have class "xxx" ?

Is is possible ?
Or, if not possible.

I have the following list:
<ul>
<li class="topCurrent">One
<ul>
<li>One-1
<ul>
<li>One-1.1
<ul>
<li class="current">One-1.1.1
<ul>
<li>One-1.1.1.1</li>
<li>One-1.1.1.2</li>
<li>One-1.1.1.3</li>
</ul>
</li>
<li>One-1.1.2</li>
</ul>
</li>
<li>One-1.2</li>
</ul>
</li>
<li>One-2</li>
<li>One-3</li>
</ul>
</li>
<li>Two
<ul>
<li>Two-1</li>
<li>Two-2</li>
</ul>
</li>
Using the following jQuery:
$("ul li ul").hide();
$("ul li").hoverIntent(
function(){
$(this).children('ul').slideDown('fast');
},
function(){
$(this).children('ul').slideUp('fast');
}
);
What this does is hide all of the ul below the top level ul until there is a hover over it.
What I would like to do is this:
If an li has a class="current" I would like that structure to be open up until the point that current is hit. It would still allow the ul below it to be displayed on a hover, as well as any other ul's, but at no point would the parents of class="current" be hidden.
Suggestions? This problem has been driving me crazy.
Thanks!
I want to get all the fields of a class without getting the underlying implementations of the class event.
type.GetFields(BindingFlags...) returns the nuderlying delegate for event fields. Does anyone knows how to filter them out ?

I have a class which has the following methods:
Public Function rumusbuffer () As Decimal
buffer = (ukuranblok - pntrblok) / (ukrnrecord + pntrblok)
Return buffer
End Function
Public Function rumusW () As Decimal
interblock = pntrblok + ((pntrblok + intrblok) / buffer)
Return interblock
End Function
how can I make the buffer can be used on its function rumusw but different forms so that her class should be re-initialization ..
but the calculation method can rumusbuffer rumusw d use in the method?
So i know how to change an id: $("body").attr('id', 'list');

Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here).
Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor?
Can traits be used to check the constructor presence?
If yes, how?
If not, why it is not possible?
I use the FindBugs Eclipse plug-in and was wondering if I can simply analyze only one class rather than the entire project? I can't seem to figure it out. Simply right-clicking on the target class doesn't seem to do anything.
I am using PHP/Java bridge to run PHP scripts on the Tomcat server. Can someone point me to an example as to how to call my PHP scripts from a Java file.
<?php
class X{
//variables
//functions
}
?>
Now I want to call the member functions of class X using its object via a Java file. How do I do this?
I am currently building a blog system, and the class file i.e class Blog{}, is running ok, when I try it on its own, but, when I try to use it in the pages of the site that have css, it looks weird and full stop, and apostrophes are replaced by strange characters! please help, this is my first time of using oo for development,
