Q:

create a custom code completion for eclipse

I am trying to make a plugin for eclipse to add more results in the code completion window. 
In order to do that i need to get a reference to the Java Editor in order to override the getContentAssistant method of the editor’s SourceViewerConfiguration.
So, how can i get that reference?
Thank you 
PS. feel free to provide any suggestions or links that can be helpful 

A:

Implement the javaCompletionProposalComputer. The link you gave is not useful, as that is only for people who implement a language editor, but the Java editor already exists.
