In this blog we will create a simple unmarshaller at deploy-time using bytecode and measure its performance. This blog is part 4 of 4, the series consists of the following posts: Writing an unmarshaller by hand Constructing an unmarshaller using reflection Generating an unmarshaller using annotations Creating an unmarshaller using...

Code is generated at many phases during the development & deployment cycle. Everyone is familiar with compile-time at which the compiler generates (byte)code. However code is generated at other times/phases as well. In this post I divide code generation into four phases. I will also discusses some of the benefits... Read more
