fillCompletionVariants

public void fillCompletionVariants(CompletionParameters parameters,
                                   CompletionResultSet _result)

Description copied from class: CompletionContributor

The main contributor method that is supposed to provide completion variants to result, based on completion parameters. The default implementation looks for CompletionProviders you could register by invoking CompletionContributor.extend(CompletionType, ElementPattern, CompletionProvider) from your contributor constructor, matches the desired completion type and ElementPattern with actual ones, and, depending on it, invokes those completion providers.

If you want to implement this functionality directly by overriding this method, the following is for you. Always check that parameters match your situation, and that completion type (CompletionParameters.getCompletionType() is of your favourite kind. This method is run inside a read action. If you do any long activity non-related to PSI in it, please ensure you call ProgressManager.checkCanceled() often enough so that the completion process can be cancelled smoothly when the user begins to type in the editor.
