Implementing filters

An example implementation of a filter is also shown on the example implementation page.

Testing your new filters

Finally, when you have implemented your filter provider and one or more new filters, you can test then by selecting Run - Debug Configurations. Right click on Eclipse Application and give the configuration a meaningful name such as Filter Test.


 

 

Press the File System...button and navigate to the root of your normal development workspace.

Press Debug to launch a new instance of Eclipse. The quickest way to check that your new filter is available is to open a class diagram and open the filter script view. Ctrl+Space will now show your new filter listed.
