Examples of org.codehaus.groovy.control.CompilationUnit$ClassgenCallback

org.codehaus.groovy.control.CompilationUnit
A callback interface you can use to "accompany" the classgen() code as it traverses the ClassNode tree. You will be called-back for each primary and inner class. Use setClassgenCallback() before running compile() to set your callback.
