処理の流れ (概要)(Execution Flows : Summary)

GetLoadedClasses() の処理

JvmtiEnv::GetLoadedClasses()
-> JvmtiGetLoadedClasses::getLoadedClasses()
   -> (1) (前準備を行う)
          -> JvmtiGetLoadedClassesClosure::JvmtiGetLoadedClassesClosure()
             -> set_this()
                -> JavaThread::set_jvmti_get_loaded_classes_closure()

      (2) 該当するクラスの個数を数える
          -> SystemDictionary::classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::increment()
          -> Universe::basic_type_classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::increment()

      (3) 個数分の配列を確保する
          -> JvmtiGetLoadedClassesClosure::allocate()

      (4) 確保した配列に該当のクラスを格納する
          -> SystemDictionary::classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::add()
          -> Universe::basic_type_classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::add()

      (5) 返却用の配列に結果をコピー
          -> JvmtiGetLoadedClassesClosure::extract()

GetClassLoaderClasses() の処理

JvmtiEnv::GetClassLoaderClasses()
-> JvmtiGetLoadedClasses::getClassLoaderClasses()
   -> (1) (前準備を行う)
          -> JvmtiGetLoadedClassesClosure::JvmtiGetLoadedClassesClosure()
             -> set_this()
                -> JavaThread::set_jvmti_get_loaded_classes_closure()

      (2) 該当するクラスの個数を数える
          -> SystemDictionary::classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::increment_with_loader()
          -> Universe::basic_type_classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::increment_for_basic_type_arrays()

      (3) 個数分の配列を確保する
          -> JvmtiGetLoadedClassesClosure::allocate()

      (4) 確保した配列に該当のクラスを格納する
          -> SystemDictionary::classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::add_with_loader()
          -> Universe::basic_type_classes_do()
             -> ... (See: #TODO)
                -> JvmtiGetLoadedClassesClosure::add_for_basic_type_arrays()

      (5) 返却用の配列に結果をコピー
          -> JvmtiGetLoadedClassesClosure::extract()
