  • each embodiment emphasizes a difference from the other embodiments, and the identical or similar parts between the embodiments may be made reference to each other. Since the apparatuses disclosed in the embodiments are corresponding to the methods disclosed in the embodiments, the description of the apparatuses is simple and relevant parts may be made reference to the description of the methods.
  • the steps of the methods or algorithms described in the embodiments of the present disclosure may be directly implemented by hardware, software modules executed by the processor, or a combination of both.
  • the software module can be placed in a random access memory (RAM) , memory, read only memory (ROM) , electrically programmable ROM, electrically erasable and programmable ROM, register, hard disk, mobile disk, CD-ROM, or any other form of storage medium known to the technical domain.
  • the instruction program may be stored in a computer-readable storage medium, and when executed, a processor executes the steps of the above method embodiments as stated above.
  • the foregoing storage medium may include various types of storage media, such as a removable storage device, a read only memory (ROM) , a random-access memory (RAM) , a magnetic disk, or any media that stores program code.
  • the integrated unit may also be stored in a computer-readable storage medium.
  • the storage medium stores instructions which are executed by a computer device (which may be a personal computer, a server, a network device, or the like) to realize all or a part of the embodiments of the present disclosure.
  • the above-mentioned storage medium may include various media capable of storing program codes, such as a removable storage device, a read only memory (ROM) , a random-access memory (RAM) , a magnetic disk, or an optical disk.
  • Logic when implemented in software can be written in an appropriate language such as but not limited to C#or C++, and can be stored on or transmitted through a computer-readable storage medium (e.g., that is not a transitory signal) such as a random access memory (RAM) , read-only memory (ROM) , electrically erasable programmable read-only memory (EEPROM) , compact disk read-only memory (CD-ROM) or other optical disk storage such as digital versatile disc (DVD) , magnetic disk storage or other magnetic storage devices including removable thumb drives, etc.
