Embodiment
Hereinafter will be elaborated to embodiments of the invention in conjunction with the accompanying drawings.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
As shown in Figure 1, the method for the invention comprises: server is the member of this portable terminal group with this mobile terminal records after receiving the foundation that portable terminal is sent or adding the request of certain portable terminal group; Send to above-mentioned server after the message block that member in the above-mentioned portable terminal group will be used to describe local graphics primitive object is built up file, give other member in the above-mentioned portable terminal group synchronously with this document by above-mentioned server; Above-mentioned other member resolves the above-mentioned file that receives and shows this graphics primitive object.Wherein, this document can be XML(Extensible Markup Language, extend markup language) file of form; This graphics primitive object can be figure that is made of single element figure or the figure that is constituted by a plurality of element figures.
When specific implementation, the member in the above-mentioned portable terminal group can also lock or not lock local graphics primitive object under user's control;
Then above-mentioned other member resolves the above-mentioned file that receives and shows this graphics primitive object, specifically comprise: when above-mentioned other member is judging local graphics primitive object and is in unlock state, the above-mentioned file that receives is resolved and shown this graphics primitive object;
When above-mentioned other member is judging local graphics primitive object and is in the lock state, the file that receives is abandoned.
In addition, the member in receiving this portable terminal group sends move back the group request after, above-mentioned server is deleted this member from this portable terminal group.
From foregoing description as can be seen, interactive messages can be divided into two kinds between server and the portable terminal: control messages and data-message.Wherein, set up the portable terminal group request, add the portable terminal group request message, move back group request message etc. and all belong to control messages, and the file of mutual XML form belongs to data-message between server and the portable terminal.
As shown in Figure 2, above-mentioned two kinds of message packets are formed by following two parts: header and message body.
Header may be defined as one hexa-atomic group, comprises following field:＜Version, Msg ID, Date, Time, Source, Destination 〉.Wherein, Version is used to indicate the version information of this message packet; Msg ID is the unique identification of this message, and this sign is provided by portable terminal or server; Date is the date of shipping of this message; Time is the transmitting time of this message; Source is message sender's a identification information, and its value adopts server-assignment to give the port numbers of portable terminal, and value is that the sender who represented this message at 0 o'clock is server; Destination is message recipient's a identification information, and value is that the recipient who represented this message at 0 o'clock is server.
The message body may be defined as a tlv triple, comprises following field:＜Type, Length, Element List 〉.Wherein, Type is used to identify type of message (index is according to type, specifically by deviser's definition); Length is used for the element number of representing that Element List field thereafter comprises; The value of each element among the Element List is used to represent a property value of the object that passes.The object that passes can be divided into two classes; One class is a graphics primitive object, and another kind of is the object of descriptive system operation, and system refers to the multi-user collaborative graphics editing software, and operation refers to the operational motion to pel.
Because the J2ME(Java 2 Micro Edition on the portable terminal) platform is not supported the serializing operation of graphics primitive object, and the attribute of graphics primitive object may comprise complicated data type (being non-Java basic data type), so, can not simply use general data stream to realize to serializing and the unserializing and the transmission thereof of graphics primitive object.The present invention uses the XML technology to realize the serializing and the unserializing of object, promptly utilizes the XML file to describe graphics primitive object, by the establishment and the parsing of XML document, finishes graphics primitive object flows to graphics primitive object to text flow and text conversion.Simultaneously, by the inlet flow (Inputstream) that the J2ME platform provides, can realize the transmission of text flow between portable terminal and the server end.
As shown in Figure 3, the course of work of server comprises:
At first on server, set up a WBServer class.As main classes, it contains the entrance function main(of program).Start a thread HelloThread in the WBServer class, the effect of this thread is on each port of monitoring service device whether the mobile terminal request login to be arranged.When having listened to mobile terminal request and server when connecting, server is at first set up Socket with this portable terminal and is connected, and takes out a current available port numbers P then, and this port numbers P is sent to above-mentioned portable terminal; And then start a thread ServerSender, close simultaneously with the Socket of portable terminal and be connected.Thread ServerSender monitors the request that portable terminal is sent on port P, when portable terminal and server after port P sets up Socket once more and is connected, set up output stream at ServerSender, be responsible for sending data to portable terminal; Start thread ServerListener simultaneously, in this thread, set up inlet flow, be responsible for reception and handle mobile terminal and send to data in server.
That is to say that server starts two thread: ServerSender and ServerListener respectively for each portable terminal.ServerSender and ServerListener share a message to row, and ServerListener is responsible for the data that the portable terminal that receives is sent are inserted into message to row; And ServerSender is responsible for reading the message in the message queue and handles.These two threads are the input and output data of processing server respectively, are in order to improve the response speed of server to portable terminal, and make user's use more natural.
The user is by behind the portable terminal logon server, can set up one and newly organize or add an existing group and discuss." group " realized by the Group class, by the forwarding of message in the user in the Group class management group, the group, the maintenance and the control concurrent operations of shared object.
When specific implementation, as shown in Figure 4, the workflow of portable terminal comprises: the user enters multi-user collaborative graphics edition master interface by portable terminal, after the logon server success, server can return existing portable terminal Groups List, the request that the user initiates certain portable terminal group of adding or sets up certain portable terminal group according to this tabulation to this portable terminal; Server sends the file of information of description graphics primitive object of the group correspondence of its adding to this portable terminal after handling above-mentioned request success, shown by this portable terminal.Certainly, what initiate when this portable terminal is when setting up the request of portable terminal group, and this document be a sky.
In the present invention, all mutual message all are one by one message object between server and the portable terminal.As shown in Figure 5, message object be delivered in the J2SE(Java2 standard edition) can adopt serializing mechanism under the platform, but the J2ME platform of mobile phone is not supported serializing mechanism, therefore can't be by serializing pass-along message object between server and portable terminal.Will be at J2ME portable terminal and J2SE server end pass-along message object, the present invention adopts following method.
The present invention realizes the serializing and the unserializing of object in conjunction with the XML technology.A mutual side is write a message object as an XML text flow according to certain form earlier, then the text is flowed in transmission over networks; Mutual the opposing party's receiving end is also resolved this XML text flow, finishes the instantiation of this object at last.This method has increased XML text flow processing layer in the object transmittance process, can cause certain influence to performance, but because advantages such as the cross-platform characteristic of XML itself, powerful descriptive power and extensibilities, and the feasible performance impact of being brought by it is insignificant.
In addition, the present invention also can adopt optimistic lock algorithm, meaning the version information of the file that server can submit to according to the member and the current version information of local corresponding record compares, if the versions of data that the member submits to number is greater than the current version of local record number, then agree to be upgraded, otherwise think stale data.Be applied to the present invention, that is: after the user edits local graphics primitive object earlier, again to the server application; The application of server parallel processing of user if agree editor, is then returned acceptance message, and is transmitted the file that this describes graphics primitive object to other user; If disagree with, then return nack message and make portable terminal return to the preceding state of editor this time.Under user on the same group is not a lot of situation, do not adopt optimistic lock algorithm, can effectively improve the response speed of system, reduce Internet traffic; Compare with the operation conversion method simultaneously, it calculates simple, and it is few to take resource, so be more suitable for using in portable terminal.
The present invention selects graphics primitive object as the unit of locking.The one, because user's operation substantially all is to be that unit carries out with the graphics primitive object, select nature like this, and be easy to realize; The 2nd, if be the unit of locking with the attribute (wherein, this attribute is meant each element figure of composition diagram meta object) of graphics primitive object, the system maintenance expense will be than too big.Therefore selecting with the graphics primitive object is that unit locks.
