Method Detail

duringCompletion

public void duringCompletion(CompletionInitializationContext context)

Description copied from class: CompletionContributor

Invoked in a read action in parallel to the completion process. Used to calculate the replacement offset (see CompletionInitializationContext.setReplacementOffset(int)) if it takes too much time to spend it in CompletionContributor.beforeCompletion(CompletionInitializationContext), e.g. doing PsiElement.findReferenceAt(int) Guaranteed to be invoked before any lookup element is selected

Overrides:

duringCompletion in class CompletionContributor

Parameters:

context - context

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.

Overrides:

fillCompletionVariants in class CompletionContributor

findJavaClassReference

public static JavaClassReference findJavaClassReference(PsiFile file,
                                                        int offset)
