rtti

I found a great explanation about the new RTTI in Delphi ,but I don't understand one important thing about all I have read - Where can I use that? What is it supposed to replace? Runner The extended RTTI works like Reflection in .NET. It gives you access to your internal application structure information. You can access class properties, methods etc.. at runtime, at extent you could not do it before. Some ways of using it: Serialization / Deserialization of classes to XML or other media Mapping of objects to databases. ORM. Cloning of objects Dynamic invocation of methods "Scanning" of object

I've heard a lot about the new/improved RTTI capabilities of Delphi 2010 , but I must admit my ignorance...I don't understand it. I know every version of Delphi has supported RTTI...and I know that RTTI (Runtime Type Information) allows me to access type information while my application is running. But what exactly does that mean ? Is Delphi 2010's RTTI support the same thing as reflection in .NET ? Could someone please explain why RTTI is useful? Pretend I'm your pointy haired boss and help me understand why RTTI is cool. How might I use it in a real-world application? RTTI in Delphi is still

Is there a simple way to duplicate all child components under parent component, including their published properties? For example: TPanel TLabel TEdit TListView TSpecialClassX Of course the most important factor, it should duplicate any new component which I drop on the TPanel without modifying the code under normal circumstances. I've heard of the RTTI, but never used it actually. Any ideas? have a read of this page Run-Time Type Information In Delphi - Can It Do Anything For You? Noting the section Copying Properties From A Component To Another which has a unit, RTTIUnit with a Procedure,

The whole generics thing is kinda throwing me for a loop, and more so the RTT. Specificis? Ah well here's the gist: enum QueryHelper { query1, query2; static <T> QueryHelper getQueryHelper (Class<T> expectedReturn) { if (expectedReturn.isInstance (SomeRelatedClass.class)) return query1; else return query2; } } and then I would call it like so: ... QueryHelper helper = QueryHelper.getQueryHelper(SomeRelatedClass.class); ... This is so that I can really flexibly assign the query return type in the actual helper. It does some casting and object creation. What I am seeing is that there is no match

In C++, is there any way to query the type of an object and then use that information to dynamically create a new object of the same type? For example, say I have a simple 3 class hierarchy: class Base class Foo : public Base class Bar : public Base Now suppose I give you an object cast as type Base -- which is in reality of type Foo. Is there a way to query the type and use that info to later create new objects of type Foo? Clone method There is nothing provided by the language that queries type and lets you construct from that information, but you can provide the capability for your class
