    • A system and method are provided to allow demand loading and discarding of Java executable image (JXE) files. The virtual machine allocates an address space for a requested JXE program. The read-only portion of the JXE file is memory mapped from its nonvolatile location to the allocated memory space using read-only mapping and the read/write section of the JXE file are loaded into memory. When a page of the JXE program is needed, a page fault occurs if the read-only portion has not been loaded into memory. The operating system's page fault handler retrieves the needed page(s) from the nonvolatile storage location based upon the mapping data that resulted from the previously performed memory mapping. Because the read-only section of the JXE file is memory mapped using read-only mapping, the operating system's paging process is free to discard previously loaded memory pages that contain read-only portions of the JXE file.
    • 提供了一种系统和方法来允许需求加载和丢弃Java可执行映像(JXE)文件。 虚拟机为所请求的JXE程序分配一个地址空间。 使用只读映射将JXE文件的只读部分从其非易失性位置映射到分配的存储空间,并将JXE文件的读/写部分加载到内存中。 当需要JXE程序的页面时,如果只读部分尚未加载到内存中,则会发生页面错误。 操作系统的页面错误处理器基于从先前执行的存储器映射产生的映射数据,从非易失性存储位置检索所需的页面。 由于JXE文件的只读部分是使用只读映射进行内存映射,因此操作系统的分页过程可以放弃先前加载的包含JXE文件只读部分的内存页。

    • A socket holding device has a plurality of posts extending from a base. The base may be arranged so that shallow wells are linearly arranged in front of deeper wells with the posts extending from the center of the wells. The posts have arms with a radial bead connected thereto receivable within receivers in the shafts of sockets. A socket may be securely retained to the base thereby preventing undesired disengagement from the well if inverted or “knocked over”, while preferably allowing free rotation of an installed socket thus enabling one to read the sizing information on the exterior surface of the socket. This design is believed to provide an ability to be installed and uninstalled from the post multiple times without a loss of grip function and also preferably requires no secondary motion to remove or release the socket, and can consist of a one-piece design.
    • 插座保持装置具有从基部延伸的多个支柱。 底座可以布置成使得浅井线线排列在较深井的前面,柱从井的中心延伸。 柱具有连接到其上的径向胎圈的臂可容纳在插座的轴中的接收器内。 插座可以被牢固地保持在基座上,从而防止不经意地脱离孔,如果反转或“敲击”,同时优选允许安装的插座自由旋转,从而使得能够读取插座外表面上的尺寸信息。 这种设计被认为提供了多次安装和卸载的能力,而不会失去抓地功能,并且优选地不需要二次运动来移除或释放插座,并且可以由一体式设计组成。
