getReferenceFilter

applyScopeFilter

public static ElementFilter applyScopeFilter(ElementFilter filter,
                                             PsiElement position)

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

isInJavaContext

public static boolean isInJavaContext(PsiElement position)

addAllClasses

public static void addAllClasses(CompletionParameters parameters,
                                 CompletionResultSet result,
                                 JavaCompletionSession session)

advertiseSecondCompletion

public static void advertiseSecondCompletion(Project project,
                                             CompletionResultSet result)

mayStartClassName

public static boolean mayStartClassName(CompletionResultSet result)

advertise

public java.lang.String advertise(CompletionParameters parameters)

Overrides:

advertise in class CompletionContributor

Returns:

text to be shown at the bottom of lookup list

handleEmptyLookup

public java.lang.String handleEmptyLookup(CompletionParameters parameters,
                                          Editor editor)

Overrides:

handleEmptyLookup in class CompletionContributor

Returns:

hint text to be shown if no variants are found, typically "No suggestions"

invokeAutoPopup

public boolean invokeAutoPopup(PsiElement position,
                               char typeChar)

Overrides:

invokeAutoPopup in class CompletionContributor

beforeCompletion

public void beforeCompletion(CompletionInitializationContext context)

Description copied from class: CompletionContributor

Invoked before completion is started. Is used mainly for determining custom offsets in editor, and to change default dummy identifier.

Overrides:

beforeCompletion in class CompletionContributor

semicolonNeeded

public static boolean semicolonNeeded(Editor editor,
                                      PsiFile file,
                                      int startOffset)
