    • A method and a system is provided for persistently storing and restoring objects of an object oriented environment established on a computer system having a volatile memory and a persistent storage. Pieces of memory, referred to as segments are allocated in the volatile memory. Then, a first list is created that contains first references to said segments. The segments are further divided into blocks. The blocks are indicated by second references. The second references are stored in a second list. In order to store an object present in the volatile memory, a block is allocated. Then an object description is created by saving the object's values of its variables. After saving the object description in the allocated block, a new element is added to the second list containing the particular reference to said created object description. Then, the references of the object descriptions of all other objects referenced in the present object are determined. These references to other objects are stored in the created object descriptions by setting the address of said referenced object description as the reference in the created object description. Finally, the second list, the segments referenced by the first list and the first list are stored on said persistent storage.
    • 提供了一种方法和系统,用于持续存储和恢复在具有易失性存储器和持久存储器的计算机系统上建立的面向对象的环境的对象。 被称为段的存储器块被分配在易失性存储器中。 然后,创建包含对所述段的首先引用的第一列表。 这些段进一步分为块。 块由第二个引用指示。 第二个引用存储在第二个列表中。 为了存储存在于易失性存储器中的对象,分配一个块。 然后通过保存对象的变量值来创建对象描述。 在分配的块中保存对象描述之后,将新的元素添加到包含对所创建的对象描述的特定引用的第二列表中。 然后,确定本对象中引用的所有其他对象的对象描述的引用。 这些对其他对象的引用通过将所引用的对象描述的地址设置为所创建的对象描述中的引用来存储在所创建的对象描述中。 最后,第二列表,由第一列表引用的段和第一列表存储在所述永久存储器上。
