Indeed this approach provides more combination +possibilities than inheritance. For instance, suppose you want to implement an +adapter MyAdapter than needs sorted local variables and intermediate stack map +frame values taking into account the local variables sort. By using inheritance, +this would require MyAdapter to extend AnalyzerAdapter, itself extending +LocalVariablesSorter. But AnalyzerAdapter is not a subclass of +LocalVariablesSorter, so this is not possible. On the contrary, by using +delegation, you can make LocalVariablesSorter delegate to AnalyzerAdapter, +itself delegating to MyAdapter. In this case AnalyzerAdapter computes +intermediate frames based on the output of LocalVariablesSorter, and MyAdapter +can add new locals by calling the newLocal method on LocalVariablesSorter, and +can get the stack map frame state before each instruction by reading the locals +and stack fields in AnalyzerAdapter (this requires references from MyAdapter +back to LocalVariablesSorter and AnalyzerAdapter). +</body> |
