What is reflection, and why is it useful? I'm particularly interested in Java, but I assume the principles are the same in any language.

The information you can get back from RTTI isn't enough to do most of the things you'd actually want reflection for though. You can't iterate over the member functions of a class for example.
How can I add reflection to a C++ application? - Stack Overflow
Is there a way in C# where I can use reflection to set an object property? Ex: MyObject obj = new MyObject(); obj.Name = "Value"; I want to set obj.Name with reflection. Something like: Reflection.
When you create a reflection on a view, Dremio will automatically update the reflection whenever the underlying data in the view changes. This means that if you're adding data to the table every few minutes, the reflection will be updated accordingly.
Reflection is the specific name for how .NET implements introspection. Other languages may call it something different (C++ calls its limited introspection RTTI, for run-time type information).
Reflection performance will depend on the implementation (repetitive calls should be cached eg: entity.GetType().GetProperty("PropName")). Since most of the reflection I see on a day to day basis is used to populate entities from data readers or other repository type structures I decided to benchmark performance specifically on reflection when it is used to get or set an objects properties. I ...
Within "Common", I have a class for common reflection tasks, like creating an instance. If I call GetExecutingAssembly, it gets all the "Common" Types, however when I use GetEntryAssembly I get the "Program" types.
