 The above snippet should be self-explanatory. The INJECT statement specifies the class in which to inject the code. In this example, it is ''Foobar''. The first block after the colon is a prologue in which you can specify imports as well as en extends and/or an implements clause. The second block contains the actual code to be injected in the type declaration itself. The above snippet should be self-explanatory.
