Content for the Eclipse JSDT Editor

Question

In Eclipse, content support is usually implemented by some class that implements IContentAssistProcessor ( JavaDoc example )

How to implement the same CompletionProposal for a JSDT editor?

The only example I know is http://code.google.com/a/eclipselabs.org/p/jsdt-jquery/ , but it is large and unclear how to extend the JSDT to help with the code.

Do other APIs exist in JSDT? Specify which APIs to use.

Answer 1

You need to implement the extension point of the add clause in the JSDT editor. There you must specify a class that implements the necessary interface, but it differs from the most general IContentAssistProcessor.

Depending on your use case, you can also look at quickAssist and quickFix extension points.
