View source for Save and load your mappings

In some programs , there are a lot of complex data structs. Suppose a complex data structure is visualized in xDIVA at first time. Finally you manage to construct a complicated mappings as follows. Although it can only take minutes, re-doing it is annoying and time consuming

You must connect so many mapping node to the ports you want, nobody want to repeat the action too many times. So we provide the save and load function in xDIVA. Although there is a know bug exist for some computers, follow this tutorial you can save and load the previous mapping easily.

In this example, we use the&nbsp;'''<nowiki>bt.ja</nowiki>va'''&nbsp;to demonstrate. You can find this file in&nbsp;'''Example/Java'''. You can follow the tutorial of&nbsp;[[A Binary Tree Node Example]]. But how to save your mapping ? When you finish connecting the mapping node and variable&nbsp;'''root'''.

You can see the option&nbsp;'''File'''&nbsp;in the upper toolbar of mapping dialog. In&nbsp;'''File'''&nbsp;opetion , you can see there are two options in this submenu. One is&nbsp;'''Save MDS File'''&nbsp;, and another is&nbsp;'''Load MDS File'''.

First , click the&nbsp;'''Save MDS File'''&nbsp;option. There will be a save dialog pop up. Default path is setted to&nbsp;'''OgreSDK/bin/debug/mds'''.

'''But please don't save mds file in this folder for now'''. There still have problems with save the file here in some computer. We are currently working on it. Anyway, please change the path to&nbsp;'''DIVA/bin/release'''.

Then enter the file name you want and press&nbsp;'''OK'''&nbsp;button.

Now , we unfold root, you can see the mapping dialog pop up. Follow the the tutorial of&nbsp;[[A Binary Tree Node Example]]. After mapping the attributes of root , click the&nbsp;'''File'''&nbsp;option again, and repeat the steps to save the mappings described above.

Here we have two saved mapping ,&nbsp;'''<nowiki>root_test1.md</nowiki>s'''&nbsp;and&nbsp;'''<nowiki>root_test2.md</nowiki>s'''&nbsp;in&nbsp;'''DIVA/bin/release'''.

Next, we will show how to load the mds file to xDIVA when xDIVA starts up. Please open the <nowiki>DIVA.md</nowiki>s file in&nbsp;'''DIVA/bin/release/mds'''&nbsp;, and edit the path like this.

Please restarting the DIVA and Minerva and visualize&nbsp;'''root'''&nbsp;again. You will see the visualization result on the window and no more mapping dialogs pop up. Then click the root to enjoy the example. All the mappings you made are already loaded automatically.
