Reflection

Reflection is the ability to examine, understand, and modify the internal structure of an object through reading/writing of metadata at runtime. Most statically typed languages have a built-in reflection capability, most likely through the use of a library.

Reflection also has a performance impact, as it requires a lot of runtime processing to perform in order to manipulate objects in memory.
