Abstract
The embodiment of the invention discloses a kind of plug-in's data processing methods of object-oriented, comprising: establishes card i/f base class, and is the Virtual Function of expansible succession by the pin function interface setting of the card i/f base class, and generate interface document；The Virtual Function in card i/f base class is inherited by realizing interface processing class, and interface processing class has definable private data and function to realize functional interface；Wherein the pin function interface includes opening interface and down interface, and the interface of opening is used to generate an interface processing class example and returns to the pointer of interface base class, to call corresponding interface processing class example function by interface base class pointer；And the down interface is for closing and deleting corresponding interface processing class example.
Description
Technical field
The present invention relates to technical field of data processing, the plug-in's data processing method of especially a kind of object-oriented.
Background technique
While C Plus Plus is good at Object-oriented Programming Design, the programming of Kernel-based methods, therefore quilt can also be carried out
It is widely applied.To realize system function dynamic expansion, the plug-in unit processing technique based on dynamic link library is generallyd use.Traditional inserts
Part processing is then mapped defined using dynamic link library direct function mapping mode, first loading dynamic link library file
Pin function interface to function, carry out dynamic call the corresponding interface function finally by this function.But it sends out in actual use
Existing, this mode makes plugin library realize and use shortage globality, and plug-in unit is easy to cause system exception, and cannot achieve band
There is the complex logic feature card of private data.
Summary of the invention
Aiming at the problems existing in the prior art, the purpose of the embodiment of the present invention is that providing a kind of plug-in unit number of object-oriented
According to processing method, can, at least partly solve defect in the prior art.
To achieve the goals above, the embodiment of the present invention proposes a kind of plug-in's data processing method of object-oriented, packet
It includes:
Card i/f base class is established, and is the void of expansible succession by the pin function interface setting of the card i/f base class
Function, and generate interface document；The Virtual Function in card i/f base class, and the interface are inherited by realizing interface processing class
Managing class has definable private data and function to realize functional interface；Wherein the pin function interface includes opening interface
And down interface, the interface of opening is used to generate an interface processing class example and returns to the pointer of interface base class, to pass through
Interface base class pointer calls corresponding interface processing class example function；And the down interface is corresponding for closing and deleting
Interface handles class example.
Wherein, the method also includes:
Plug-in unit dynamic link library file is loaded, and maps the dynamic base interface function for opening interface and down interface；
Dynamic base interface function is opened to obtain the pointer and interface document of the interface base class, and interface base class pointer
Corresponding interface function is called to realize that plug-in unit is handled.
The advantageous effects of the above technical solutions of the present invention are as follows: above-mentioned technical proposal proposes a kind of inserting for object-oriented
Part data processing method relies on C++ Object-oriented Technique to be packaged processing so that plugin library has face to pin function interface
To Properties of Objects, to reduce the difficulty of developing plug and realize the complex logic feature card for having private data.
Detailed description of the invention
Fig. 1 is the dongle configuration schematic diagram of the embodiment of the present invention；
Fig. 2 is the plug-in unit implementation process schematic diagram of the embodiment of the present invention；
Fig. 3 is the plug-in unit use flow diagram of the embodiment of the present invention.
Specific embodiment
It is right with reference to the accompanying drawings and detailed description in order to illustrate a kind of object-oriented plug-in unit processing method of the invention
The present invention is described in further detail.
The embodiment of the present invention proposes a kind of plug-in's data processing method of object-oriented, and core is to propose one kind
Card i/f base class as shown in Figure 1 leads in the Virtual Function that the pin function interface of the card i/f base class is expansible succession
It crosses and realizes that interface processing class is come after the Virtual Function in birdsmouth base class, so as to realize corresponding interface function；Meanwhile it connecing
The realization of functional interface can be facilitated in mouth processing class with customized private data and function.Practical pin function of the invention connects
There are two mouthful, one is to open interface (open), and an interface processing class example can be generated by opening interface, and return to interface base class
Pointer, corresponding interface processing class example function can be thus called by interface base class pointer；The other is closing
Corresponding interface processing class example can be closed and be deleted to interface (close).
Detailed process is as shown in Figure 2, defines a card i/f base class, and the pin function interface in the base class first
For the Virtual Function of expansible succession, and generate the interface document that user uses；It defines and realizes that interface processing class is come after birdsmouth
Virtual Function in base class realizes corresponding interface function；Private data and function are defined in interface processing class to facilitate function
The realization of interface；Dynamic link library is constructed, interface and down interface Outside Access interface is opened to realize, is created in opening interface
Interface processing class instance objects are built, and return to interface base class pointer；Realize that down interface handles class example pair in down interface
As.
Wherein, details are as follows for object-oriented plug-in unit usage mode:
As shown in figure 3, loading plug-in unit dynamic link library file first, interface and down interface dynamic bank interface are opened in mapping
Function obtains interface base class pointer by opening interface function, then uses document according to interface, can by interface base class pointer
To call corresponding interface function, to realize plug-in unit processing function.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
