Hi guys, I've defined a method in a class: public void setCollection(Collection<MyClass>); and in another class public void setCollection(Collection<OtherClass>); (and really, lots of similar classes) All are in classes with the same superclass, and I have a method in a support-class where I want to call this method and set it wit...
Groovy offers some really neat language features for dealing with and implementing Java interfaces, but I seem kind of stuck. I want to dynamically implement an Interface on a Groovy class and intercept all method calls on that interface using GroovyInterceptable.invokeMethod. Here what I tried so far: public interface TestInterface { ...

I wish to automagically discover some information on a provided class to do something akin to form entry. Specifically I am using reflection to return a PropertyInfo value for each property. I can read or write values to each property from my "form", but if the property is defined as "int", I would not be able to, and my program should n...
I'm trying to write a method that will get a private field in a class using reflection. Here's my class (simplified for this example): public class SomeClass { private int myField; public SomeClass() { myField = 42; } public static Object getInstanceField(Object instance, String fieldName) throws Throwable {...
I need to log all the function parameters in a dozen functions. Is there a way to pro grammatically determine all the parameters and their values (or at least their .ToString() value)? Perhaps via reflection? ...
Hi all. I am implementing a sort of ORM in Java. I am trying to do a static find method that is only in the parent class. Let me get to the point: public class DB { public static Object find (int id) { // i want to return anew instance of the calling subclass } } public class Item extends DB { // nothing here } public class ...
So for example: class GrandParent { public int GrandProperty1 { get; set; } public int GrandProperty2 { get; set; } } class Parent : GrandParent { public int ParentProperty1 { get; set; } public int ParentProperty2 { get; set; } protected int ParentPropertyProtected1 { get; set; } } class Child : Parent { publi...
Hello. I have problems with redrawing child controls of cloned panel. First, I'm not using IClonable. I'm using reflection. My code: public static Panel ClonePanel(Panel panel) { Panel newPanel = (Panel) CloneControl(panel); foreach (Control ctl in panel.Controls) { Control newCtl = CloneControl(ctl); newC...
If you have a property defined like this: private DateTime modifiedOn; public DateTime ModifiedOn { get { return modifiedOn; } } How do you set it to a certain value with Reflection? I've tried both: dto.GetType().GetProperty("ModifiedOn").SetValue(dto, modifiedOn, null); and dto.GetType().GetProperty("modifiedOn").SetValue(d...

Let's say I have a class like this (and also further assume that all the private variables: public class Item { private String _id = null; private String _name = null; private String _description = null; ... } Now, if I want to build a toString() representation of this class, I would do something like this inside ...
Hi, I'm pretty new to Java, and I'm facing a reflection issue. Let's say i have to dynamically call the method fooMethod on an instance of the class Foobar I got so far an instance of Foobar with: Object instance = Class.forName("Foobar").newInstance(); Let's say I know there's a method fooMethod on this object (I can even check t...
Given the string "string[]" and asked to get the underlying Type for this class, one might start with: private Type getTypeByName(string typeName) { if (typeName.EndsWith("[]")) { return something; // But what? } return Type.GetType(typeName); } What type is "string[]" and how does one reflect the type out...
When reflecting on an interface type, I only get the members of the specific type, not inherited members. In this over-simplified example, the program only prints "Name", not "ItemNumber", "Name" as I would expect: using System; public interface IBasicItem { string ItemNumber { get; set; } } public interface IItem : IBasicItem { ...
I have something like this: public class Foo { public Bar[] Bars{get; set;} } public class Bar { public string Name{ get; set; } } I start reflecting: PropertyInfo propertyInfo = typeof(Foo).GetProperty("Bars"); so far so good. I want to reflect deeper: Type type = _propertyInfo .PropertyType; // this gives me that the t...
