Problems solved by technology

However, this technology needs to generate 3 additional auxiliary objects for each object in the system, and generating these objects requires a large amount of computing time and memory space for the computer, so this method greatly increases the time and space consumption of the software, and the usability is low , compared with not using the dynamic update method, the running time is increased by 1.13% on average, and the memory usage is increased by 6.36% on average

Embodiment

[0026] Such as figure 1 As shown, the service object state transfer system in the pervasive service dynamic update involved in this implementation includes: an object proxy management module and an object state conversion module, wherein: the object proxy management module is connected to the object state conversion module to transmit service object information.

[0027] The function of the object proxy management module is to monitor the registration and request events of services in the pervasive environment, and generate a proxy object for the newly registered pervasive service object, and the proxy object will hold the reference of the registered pervasive service object , all service calls to the universal service object will also be executed through the object proxy management module, and the object proxy management module provides the reference information of the required service object to the object state transition module. The object proxy management module includes: ...

Abstract

The invention discloses a service object state transfer system in pervasive service trend update and a method thereof, belonging to the technical field of computer application. The system comprises an object broker management module and an object state transfer module, wherein the object broker management module comprises a pervasive environment monitoring submodule, a service object broker management submodule and a service object quotation query interface submodule; the object state transfer module comprises an object state extraction submodule, an object state injection submodule and an object state transfer submodule; and the method comprises the steps of monitoring service register, trigging and updating event, extracting the state of the original service object source and injecting an objective state to a new service object. The invention has little occupied time and space and high performance and can solve the state transfer problems of any state form including common members, arrays, lists and hash tables, therefore, the invention has wide range of application.

Description

technical field [0001] The present invention relates to a system and method in the field of computer application technology, in particular to a system and method for service object state transfer in dynamic update of pervasive services. Background technique [0002] With the continuous expansion of computer applications, people realize that computers will go deep into people's lives, fill every corner of life, and exist in any form people want. Thus the concept of ubiquitous computing was born. Ubiquitous computing splits software functions into individual services, which can be deployed in different places. These services can be independently developed and compiled in different environments, and the actual application system can be built through appropriate assembly methods, so that the services can be reused and shared, and their service life is no longer limited by a certain service life like traditional code modules. applications. Due to the extension of the life cycl...
