In such cases, the method for present embodiment specifically may further comprise the steps:
S1, system initialization comprise: system global variables initialization, the initialization of level combobox, the initialization of right mouse button menu etc.;
S2, send the HTTP request: present embodiment based on client computer the architecture mode of server.Node data is stored among the database D B of server end, and topology represents and be implemented in foreground client, as shown in Figure 4.Therefore client needs to represent request and is sent to server end before representing, and the backstage service of server end is carried out the inquiry and the Algorithm Analysis of node relationships according to request, and result set is configured to the xml formatted data is sent to client.
Further, for the first time accessed when system, send the HTTP request according to init state to server end, to represent the topology diagram of system initialization; Mouse is double-clicked incident and combobox is selected incident when taking place, and according to selecteed father node id, sends the HTTP request to server end, to realize with the father node serving as to pay close attention to node, represents topology diagram;
Further, when needs are preserved layout and removed layout, travel through current all ordinary nodes, obtain node i d and coordinate figure.Send parameter list in the POST mode to server end.The layout operation is preserved or removed to server end according to HTTP request execution.
S3, loading relation data and node data: client loading result collection data.After sending the HTTP request to server end, server end carries out associative operation and result set is configured to xml form response data.Thus, client need load this xml form response data.
S4, picture: the response data of traversal xml is also drawn.
Further, xml form response data comprises two aspect contents, is respectively node data and relation data.Node data comprises the attributes such as id, description and coordinate of node.Relation data comprises the id of two nodes of connection.The process that the process of traversal xml form response data is just drawn specifically, at first empties topology interface, then all nodes of current level is plotted on the topology interface, draws line according to the node relationships data then.
In order to improve the topology interface friendly, in procedure for displaying, added the progress displaying bar according to procedure for displaying and shown.
Whether can operate for " the preservation layout " and " removing layout " of controlling right-click menu, in procedure for displaying, judge that if current topological structure is strivied for survival at ordinary node, then " preservation layout " can operate according to node type; If it all is empty having ordinary node and coordinate among the current topological structure figure, the layout of not preserving current topology diagram before showing, then " removing layout " can not operate, otherwise, can operate.
For the topology diagram after realizing preserving represents fast, in procedure for displaying, judge according to node coordinate, when the coordinate of a node is not sky, this node does not just need autoplacement so, therefore according to the coordinate of this node, just can be according to prior art directly with node locating in corresponding coordinate, can stop autoplacement; Concrete grammar repeats no more.
For the more perfect satisfied node of clicking makes its line colour change function, after drafting finishes, will put node and click the variable color flag bit for empty.
As long as can determine the content of this xml form response data, i.e. node data and relation data.Just can represent topology diagram according to prior art, concrete grammar repeats no more.
S5, monitoring mouse-click: when the user wishes to highlight certain node, during this node of mouse-click, import this node i d into, realize the line variable color of the node of this node i d correspondence, specifically, according to the annexation data that comprise this node, adopt other color to redraw the line of all these nodes and other node exactly;
S6, monitoring combobox: according to the feature that wide area network network element device level distributes, system provides 2 grades of levels for topological node.Therefore the combobox of 2 grades of interlocks need be provided, realize paying close attention to the node mode and check topology diagram;
When selecting the one-level combobox, send HTTP request (S2), the secondary combobox carries out data linkage according to the data that the user selects in the one-level combobox.Simultaneously, load annexation response data (S3), realize with this one-level node serving as to pay close attention to node, represent topology diagram (S4);
When selecting the secondary combobox, send HTTP request (S2), load annexation response data (S3), realize with this two-level node serving as to pay close attention to node, represent topology diagram (S4);
S7, monitoring mouse are double-clicked:
When double-clicking the one-level icon, be similar to and select the one-level combobox, send HTTP request (S2), the secondary combobox carries out data linkage according to the data that the user selects in the one-level combobox.Simultaneously, load annexation response data (S3), realize with this one-level node serving as to pay close attention to node, represent topology diagram (S4);
When double-clicking the secondary icon, be similar to and select the secondary combobox, send HTTP request (S2), load annexation response data (S3), realize that this two-level node for paying close attention to node, represents topology diagram (S4);
S8, monitoring right mouse button: when right mouse button generation incident, can make corresponding operating according to the menu item of user's selection.System provides following menu item for right button: preserve layout, remove layout, start stop autoplacement;
S8.1, preservation layout: travel through id and the coordinate of all nodes to obtain each node of current demonstration, and each node i d and the coordinate correspondence of being obtained is kept in the topology data.Realize that " moment " represents so that open this topology diagram next time;
Further, because the complexity of network topology structure, one-level node and two-level node may occur in many levels, so the coordinate of one-level node and two-level node is not saved.On the contrary, ordinary node can only occur in a level.If therefore do not have ordinary node among the current topological structure figure, the preservation place function then be not provided.
S8.2, remove layout: all nodes that travel through current demonstration to be obtaining the id of each node, and the coordinate of the node i d correspondence obtained in the topology data is removed;
Further and preserve layout in like manner, if there is not ordinary node among the current topological structure figure, then do not provide the removing place function.In addition, if do not preserve before the current topological structure figure, just server end does not have not provide the removing place function under the relative recording information state of current topological structure figure yet.
S8.3, start stop autoplacement: with the continuous computing node coordinate of a kind of repeating query mode, realizing autoplacement, and this repeating query mode occupying system resources is bigger, makes the interface alternation response slow in automatic layout algorithm.When all nodes are finished layout, can manually stop autoplacement, to reduce taking of system resource;
Further, when opening a topology diagram, system default just no longer provides to start the autoplacement function for starting the autoplacement state this moment at every turn; After autoplacement was stopped, just no longer provided and stop autoplacement this moment.
Above-mentioned steps S5, S6, S7 and S8 are in no particular order; Above-mentioned steps S8.1, S8.2 and S8.3 are also in no particular order.
Present embodiment can adopt comparatively general xml formatted data, as long as respective x ml is provided formatted data, i.e. node data and relation data are just can represent topology diagram.Certainly during practical application, be not limited to adopt the xml formatted data,, just can use as long as the data of other form can provide node data and relation data.
The xml formatted data is as follows:
<root>
＜!--node data--〉
<Node/>
＜!--relation data--〉
<Edge/>
</root>
Wherein node data comprises information such as node i d, node description, node type (one-level node, two-level node, ordinary node), one-level node code, two-level node code, node coordinate, icon path, and is as follows:
<Node?id＝″″desc＝″″nodeType＝″″lev1Code＝″″lev2Code＝″″x＝″″y＝″″iconPath＝″″/>
One-level node code and two-level node code are the unique identification of server end to these two kinds of nodes.Node i d is the unique identification of each icon in the client topology interface.
Relation data comprises the node i d of two nodes of connection.As follows:
<Edge?fromId＝″″toId＝″″/>
If a node is the ordinary node type, the one-level node code of this node and two-level node code can not be sky so, because an ordinary node is under the jurisdiction of a two-level node, a two-level node is under the jurisdiction of an one-level node.
If a node is the two-level node type, the one-level node code of this node and two-level node code can not be sky so, because a two-level node is under the jurisdiction of an one-level node.
If a node is the one-level node type, the one-level node code of this node can not be sky so.
If a node is one-level node or two-level node type, the coordinate of this node is empty so, because in topology diagram, one-level node icon and two-level node icon can not be positioned.
Network topology structure figure when serving as the concern node with two-level node " city's net 1 " as shown in Figure 5; Can come the node of presentation graphs 5 to connect situation with following xml file, as follows:
<root>
＜!--node data--〉
