Mapping a set of properties to another set where multiple source properties may be used in conversion rules?
I have a set of properties defined, the values are all stored as strings. I need to return a new set of properties where the value of each new property may derived in one of 3 ways.

How to get the list of all attributes of a Java object using BeanUtils introspection?
I have method which gets a POJO as it's parameter. Now I want to programmatically get all the attributes of the POJO (because my code may not know what are all the attributes in it at run time) and need to get the values for the attributes also. Finally I'll form a string representation of the POJO. I could use ToStringBuilder, but I wa...
What's wrong with this reflection code? GetFields() is returning an empty array.
C#, Net 2.0 Here's the code (I took out all my domain-specific stuff, and it still returns an empty array): using System; using System.Collections.Generic; using System.Text; using System.Reflection; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { ChildClass cc = n...

Non-code-generated forwarding shim for testing private methods
In general, I design classes in such a manner as to not require access to privates for testing purposes. An InternalsVisibleTo can also assist. However, I'm currently dealing with a codebase that has a few area which have become reliant on the private accessors mechanism in VSTS (i.e., using VSCodeGenAccessors to generate *_Accessor cl...
C# String representation of method
Is there a way in .NET 3.0 (or earlier) to get a string representation of a method? I know that I can get an IL byte array from a MethodBody object, but I'm interested in getting a string that essentially represents the method body as it appears to my eyes in VS. I've poked around in the CodeDom namespace to see if there was a way to co...

How to determine what object[] passed as parameter contains?
I think that this problem can be sorted using reflection (a technology which I'm not too sure about). My code is receiving some code objects that have been serialised to XML at runtime. When I receive it and deserialise it one field is causing me some hassle. There is a field that can contain a combination of the following data classes...
Bad idea to rethrow ex.InnerException?
Basically, my question is short and sweet: Is the following a bad idea (encapsulating and rethrowing ex.InnerException instead of ex) (There's a similar question here, but not quite... I want to reencapsulate the InnerException, so the stack trace is preserved without reflecting on internals) public abstract class RpcProvider { pub...

How to determine when an application started using java reflection has completed
Hello developers! I have a Java program that uses reflection to find and invoke the main(String[] args) method of another Java program. This other program is usually a Swing App that tends to spawn its own threads. I was wondering if there was a way to determine when this other 'program' terminates. I'm not sure if there is anyway to de...

Java reflection: How do I override or generate methods at runtime?
Hello! It is possible in plain Java to override a method of a class programmatically at runtime (or even create a new method)? I want to be able to do this even if I don't know the classes at compile time. What I mean exactly by overriding at runtime: abstract class MyClass{ public void myMethod(); } class Overrider extends MyCla...
