Abstract

An object-oriented management device for ASN.1 message is provided, which includes: an ASN.1 bottom supporting module for compiling the ASN.1 message into programming language example code; a common manipulation module for processing the message to support the message applications; a message plug-in for creating the message corpus plug-in from the code generated by the common manipulation module, with the class description table being the plug-in interface. The present invention solves the problem that the message structure example should be re-established after the message is persistently saved, overcomes the disadvantage that the data type of the bit stream must be known in advance for decoding, decreases the difficulty of message construction, and significantly lessens the workload of the message development and maintenance.

Claims

1. An object-oriented management device for an ASN.1 message, comprising:

at least one computing device,

an ASN.1 bottom support module for compiling the ASN.1 message into a programming language example code;

a common manipulation module for processing the message to support message applications;

wherein, the device further comprises a message plug-in for generating message corpus plug-in from the code generated by the ASN.1 bottom support module, with a class description table being a plug-in interface;

during generating the message corpus plug-in, using virtual functions to supplement class description information including class structure description information and functions for creating a class example;

adding a support of class example manipulation for the generated code;

establishing a TopClass class description table including the corresponding relationship between a TopClass name and a description in the generated code, and the TopClass is a top-layer class but not a child-class;

wherein the common manipulation module or the message plug-in is used to recover a programming language message example from data of VAL format; and

each module being executable in the at least one computing device.

2. The device of claim 1, wherein said programming language example code is C++ or JAVA™

programming code.

3. The device of claim 1, wherein for a simple data type and a composite data type, said common manipulation module or message plug-in supplements type name, integer value and class example create function of the data type;

for SET and SEQUENCE data, supplements a name of each member, sets whether the data type is optional and supplements the corresponding table of the member'"'"'s description information;

for ENUM, supplements the corresponding table between a member symbol and a number value.

4. The device of claim 1, wherein said common manipulation module or message plug-in adds the class description table in the programming language example code, shows the class description information in a form of class description table, takes a class name as a key word, and sorts elements in the table according to the class name or makes them as a hash table to be indexed conveniently.

5. The device of claim 1, wherein:

for the simple data type, adding the support of the class example manipulation in the programming language example code by the common manipulation module or the message plug-in comprises;

adding a support of the virtual functions to obtain and set a data value;

for the composite data type, adding the support of the class example manipulation in the programming language example code by the common manipulation module or the message plug-in comprises;

a) adding a support of a point marker path;

b) adding a support of setting a symbol to show whether members in SEQUENCE and SET exist or not;

c) adding a support of obtaining a length of a data array, setting the length of data and traversing elements in the data array for a SEQUENCE OF data array and a SET OF data array;

d) adding a support of a selection operation for CHOICE data;

e) adding a support of setting ANY data, which can set or obtain a variable of a real type;

f) adding a support of obtaining an object of the corresponding child-node through the point maker.

6. The device of claim 1, wherein the common manipulation module uses an AsnTreeObject tree link list to indicate a structure of the ASN.1 message.

7. The device of claim 1, wherein the common manipulation module or the message plug-in is used to generate VAL data from the generated code.

8. The device of claim 7, wherein the common manipulation module or the message plug-in is used to convert the VAL data into XML data.

9. The device of claim 6, wherein said object-oriented management device for an ASN.1 message also comprises a graphic interface package and a graphic message edition module,

wherein said graphic interface package is used to develop a graphic interface;

said graphic message edition module uses the graphic package and the common manipulation module to provide a user with a graphic interface message edition function to modify, create and edit the ASN.1 message by a way of modifying the AsnTreeObject tree link list.

10. The device of claim 6, wherein said object-oriented management device for ASN.1 message also comprises a script support package and a message script manipulation module,

wherein said script support package is used to run a script and support script extension;

said message script manipulation module uses the script support package and the common manipulation module to add an ASN.1 message manipulation function in the script to modify, create and edit the ASN.1 message by the way of modifying the AsnTreeObject tree link list.

11. The device of claim 2, wherein the common manipulation module uses an AsnTreeObject tree link list to indicate a structure of the ASN.1 message.

12. The device of claim 3, wherein the common manipulation module uses an AsnTreeObject tree link list to indicate a structure of the ASN.1 message.

13. The device of claim 4, wherein the common manipulation module uses an AsnTreeObject tree link list to indicate a structure of the ASN.1 message.

14. The device of claim 5, wherein the common manipulation module uses an AsnTreeObject tree link list to indicate a structure of the ASN.1 message.
