Fruit.
In this example, java applet and Linux based on DBus are provided according to the DBus mechanism of the embodiment of the present application
Well-bedded communication mechanism between C/C++ program can be divided into following several parts:
1.Java program calls top section of the JNI library write by C/C++ as entire communication mechanism by JNI.
2. entire top section is that a ghost is not related to the realization of functional requirement, java applet is basis
Function needs to go to call the API in JNI library.
The library 3.JNI, which encapsulates, meets the API of Java functional requirement to supply Java layers of calling, but there is no have for JNI library
Function required for body is realized, and only encapsulate the API in the library CAPI of another C/C++.
Floor portions of the Linux C/C++ program of the library 4.CAPI and bottom as communication mechanism, being mainly responsible for function needs
The completion asked.
The library 5.CAPI encapsulates a large amount of API to obtain the data and state of bottom Linux C/C++ program, but CAPI
API inside library is not the simple interface for calling Linux C/C++.
The API in the library 6.CAPI carries out interprocess communication by the Linux C/C++ of DBus and bottom, to realize data
Interaction.As shown in figure 3, API and Linux C/C++ in the library CAPI is connected with DBus can generate internal connect and outside respectively
Connection, and the internal connection and external connection are unique identification of the two processes in DBus finger daemon.
7.Linux C/C++ program will create a large amount of object and thus object binding path as server-side and interface is made
For its mark.And the object also has a virtual table, this virtual table is really that a Function Array (realizes function
The function interface of demand).
8. the method in the path of object, interface and virtual table is all that the library CAPI and Linux C/C++ program are negotiated
Alright.Linux C/C++ encapsulation complete after, CAPI can by its inside connect and all objects path,
Interface and method realize corresponding functional requirement.
Api interface in 9.CAPI is connected with Linux C/C++ program by same DBus bus, then according to each
The difference of API function, by different paths and interface go call recipient Linux C/C++ program method obtain data or
Person completes corresponding function.
API in 10.CAPI can be waited after having invoked the method in Linux C/C++ to be returned the result, and the library CAPI
Corresponding data can be got according to this result or whether arbitration functions run succeeded.
It can be seen that well arranged based on the java applet of DBus and the communication mechanism of Linux C/C++ program, it is entire on
Layer part is responsible for interacting with extraneous and floor portions, and floor portions are responsible for completing corresponding functional requirement and return result
Upper layer is transmitted to be supplied to the end Java.
Also, the underclad portion of the java applet based on DBus and the communication mechanism of Linux C/C++ program is by the library CAPI
It is responsible for interacting with top section, Linux C/C++ program is then called by DBus to complete corresponding function and will tie
Fruit returns to JNI library.
The library CAPI has not only acted as connection upper layer and the Central Terminal Station effect of Linux C/C++, is also based on DBus's
The key of java applet and the communication mechanism of Linux C/C++ program, it has been solved perfectly JNI library and has called directly LINUX C/C+
The disadvantages of high degree of coupling brought by+library, low development efficiency.Also, it is interacted by DBus and Linux C/C++ program
So that entire communication mechanism more has a sense of hierarchy, the degree of coupling is low, and development efficiency is high.
