    1.35 +Provides some useful class and method adapters. <i>The preferred way of using
    1.36 +	these adapters is by chaining them together and to custom adapters (instead of
    1.37 +	inheriting from them)</i>. Indeed this approach provides more combination
    1.38 +possibilities than inheritance. For instance, suppose you want to implement an
    1.39 +adapter MyAdapter than needs sorted local variables and intermediate stack map
    1.40 +frame values taking into account the local variables sort. By using inheritance,
    1.41 +this would require MyAdapter to extend AnalyzerAdapter, itself extending
    1.42 +LocalVariablesSorter. But AnalyzerAdapter is not a subclass of
    1.43 +LocalVariablesSorter, so this is not possible. On the contrary, by using
    1.44 +delegation, you can make LocalVariablesSorter delegate to AnalyzerAdapter,
    1.45 +itself delegating to MyAdapter. In this case AnalyzerAdapter computes
    1.46 +intermediate frames based on the output of LocalVariablesSorter, and MyAdapter
    1.47 +can add new locals by calling the newLocal method on LocalVariablesSorter, and
    1.48 +can get the stack map frame state before each instruction by reading the locals
    1.49 +and stack fields in AnalyzerAdapter (this requires references from MyAdapter
    1.50 +back to LocalVariablesSorter and AnalyzerAdapter).
