Powerful Metaprogramming Techniques With Groovy

Metaprogramming is a key component in building truly dynamic and flexible applications with Groovy. Groovy's metaprogramming capabilities bring great new possibilities to the table that would be very difficult or just plain impossible to write with Java alone. This session will demystify a lot of the magic that seems to be going on inside of a Groovy application. When Java developers are first introduced to Groovy one of the first things they notice is how much easier things are in Groovy compared to Java. Boilerplate code typically generated by your IDE all melts away to nothing in a Groovy bean. Creating XML is a snap, not a tangled mess. File I/O is a breeze. Those developer productivity gains are an important part of the story. However, in addition to making easy the things you are used to doing the hard way Groovy brings whole new capabilities to the party that Java developers don't even think about because you can't do those things with Java. Many of those capabilities are made possible because of the powerful metaprogramming capabilities of the language. Learning the metaprogramming capabilities of the language takes developers the rest of the way to fully taking advantage of the power of Groovy. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts.
