/**
 * Record the WS transformation intermediate results and context.
 * 
 * The WSState is globally exisits, however, some types need be refreshed
 * each time a WSCodeGenerator begins
 * 
 * Globally table: target methodDef -> Fast/Slow MethodSynth
 *    used to identify whether one method is target or not, and used for other places to generate right call
 * 
 * State Related:
 *    all types
 * 
 * 
 * And provide interfaces for WS code gen to query a method is a target method or not
 * 
 * Every target method and the corresponding inner class(es) will be stored here.
 * In other procedures, it need query the map.
 * If it is a target method, it need transform method call to
 *  (1) A new innerclass instance
 *  (2) invoke the fast method on the instance
