Description of drawings

Fig. 1 is a structural representation of the present invention.

Embodiment

Home network middleware development device as shown in Figure 1 comprises graphical user interface, document analysis module, template parsing module, IGRS's service output terminal; The document analysis module comprises Lexical Analysis Module, syntax Analysis Module, and Lexical Analysis Module links to each other with syntax Analysis Module; The template parsing module comprises template file storehouse, code generation module, and the template file storehouse links to each other with code generation module;

Graphical user interface links to each other with Lexical Analysis Module, template file storehouse respectively; Syntax Analysis Module links to each other with code generation module; Code generation module is served output terminal with IGRS and is linked to each other.

By the graphic interface input wsdl document of graphical user interface, select the user side programming language, promptly select suitable template; According to the parameter of graphical user interface input as: be that requirement C and XML transform or C++ and XML change mutually, the template analysis module can select suitable template file to handle in the template file storehouse.

Wsdl document from the input of graphical user interface carries out morphology, grammatical analysis in the document analysis module, obtain label and semantic values.The grammar rule of document analysis is as follows: “ $N occurs " label of form is to need the part of replacing in the template file, N represents numeral here, as $1 ， $2.

The syntactic definition of document analysis is as follows:

Lexical analysis: Lexical Analysis Module is that the program character in the wsdl document of input is converted into a series of word, and word types comprises reserved word, identifier, operational symbol, boundary's symbol and constant, uses the sign of the type of word as word; Give grammatical analysis the word that can discern then.

Grammatical analysis: syntax Analysis Module has a semantic stack, deposit the nonterminal symbol that it analyzes and the semantic values of terminal symbol, here semantic values are integers, when syntactic analyser identifies certain sentence pattern, it promptly carries out reduction with corresponding syntax rule, before carrying out reduction, finishes the Semantic Actions that the user provides earlier, these Semantic Actions can be to return the semantic values of grammatical symbol, also can be the semantic values of asking some grammatical symbol; And, output in the template parsing module identifying as label.

Code generation module in the template parsing module obtains object code according to the semantic values and the label of grammatical analysis.

The principle of work of code generation module is as follows:

Code generation module reads the template file of appointment, and template file is imported to the character string buffer zone;

Code generation module obtains the semantic values of syntax Analysis Module output; According to the semantic values generating code, and according to label the code that generates is deposited in resolution file or the java standard library file and goes, produce corresponding source code, comprise client middleware code and server end middleware code.

Whether the generation of object code is then according to user's setting: source code is made amendment, then directly generate object code as not revising.Object code generates the back and calls the respective service program by IGRS's service output terminal.

The application of home network middleware in concrete IGRS services request is as follows, and SOAP is based on the agreement of XML, by the structurized data of 80 port transmission XML of http:

(1) start the IGRS protocol stack, the IGRS service end is issued online declaration, the client search service;

(2) create session;

(3) client call remote service;

(4) home network middleware is converted into the language of XML form, i.e. soap message with the local program language;

(5) IGRS will ask to send with the form of SOAP bag, can be wired or wireless send mode;

(6) service end receives the SOAP request message, calls corresponding middleware, and XML is converted into the local program language, calls corresponding service routine and handles this request.

The process of transmitting of request response and the process of transmitting of service request information are similar, repeat no more.

The template parsing module provides java standard library to write interface, can write new library file at any time and be kept in the template file storehouse, is with good expansibility.
