dynamic-class-creation

问题 I want to dynamically create classes at runtime in python. For example, I want to replicate the code below: >>> class RefObj(object): ... def __init__(self, ParentClassName): ... print "Created RefObj with ties to %s" % ParentClassName ... class Foo1(object): ... ref_obj = RefObj("Foo1") ... class Foo2(object): ... ref_obj = RefObj("Foo2") ... Created RefObj with ties to Foo1 Created RefObj with ties to Foo2 >>> ... but I want the Foo1, Foo2, Foo classes to be created dynamically (ie: during

问题 I want to unit test my code which will have to create a .java file compile it and then the corresponding .class file should be created. How can I create the test to see if the ".class" file is created? I have added test already for its existence, now I'm trying to test the file is a valid class file. I tried try { Class.forName("Hello"); throw AssertError(); } catch( ClassNotFoundException e ) { } program.createClass(); Class.forName("Hello"); But I don't really know how to dynamically add

问题 I know I can generate a class at runtime by executing $obj = (object)array('foo' => 'bar');+ this way I can use echo $obj->foo; //bar What if want to make $obj inherits from an existing class? What I wanna achive: I'm forking paris project on github (https://github.com/balanza/paris). It's an active record class. I wonder I need to declare a class for every object, even if it's empty: class User extends Model{} I guess I might use dynamic object to avoid this boring stuff. 回答1: You could

问题 I am reading a bunch of XML files into a list (IEnumerable really) of XElements. Then I want to convert the XElement list (these XElements contain a bunch of child-elements) into a list of classes, so I can do later operations with the data more easily. Now if I know in advance the structure of XElements, this would be easy; I'd just create a class that mimics the XElement structure and fill instances of it with the XElement contents. But here's the caveat; my XML file element structure is

问题 Using the Bukkit-API I'm currently trying to create a plugin which can compile java code of a given pastebin link at runtime and execute that code. Everything is working so far except for one thing: I'm getting a ClassNotFoundException when I'm trying to access one of the already loaded plugins. (I'm not getting an exception when I'm using Bukkit-API methods!) All plugin jars have been added to the classpath; it currently looks like this: /home/cubepanel/test-network/jars/craftcubbit.jar:

问题 Using Delphi 2010 SQLQuery1.First; // move to the first record while(not SQLQuery1.EOF)do begin // do something with the current record // What's the code should i write in this part in order to create a TEdit // containing the user fullname the current item. ShowMessage(SQLQuery1['whom']); SQLQuery1.Next; // move to the next record end; 回答1: Well, to create a TEdit you need to do the following: Create a variable to work with. Either a local variable or a class member. Edit: TEdit; Then you

问题 Does anyone know how to use Java for Strong code mobility? Have you ever done it before? Here's what I try to achieve. Suppose we have 2 separate Java applications that communicate over network. App A and App B. App A has a class x instantiated as an object, and has been using it. App B has no prior knowledge of this class x. App A needs to migrate the instance of class x over to App B. App B should be able to dynamically load class x, and retains the state of class x. I have Googled around
