Method Detail

getParametersForLookup

public java.lang.Object [] getParametersForLookup(LookupElement item,
                                                  ParameterInfoContext context)

Specified by:

getParametersForLookup in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

couldShowInLookup

public boolean couldShowInLookup()

Specified by:

couldShowInLookup in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

findElementForParameterInfo

public PsiAnnotationParameterList findElementForParameterInfo(CreateParameterInfoContext context)

Description copied from interface: ParameterInfoHandler

Find psiElement for parameter info should also set ItemsToShow in context and may set highlighted element

Note: it is executed on non UI thread

Specified by:

findElementForParameterInfo in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

showParameterInfo

public void showParameterInfo(PsiAnnotationParameterList element,
                              CreateParameterInfoContext context)

Specified by:

showParameterInfo in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

findElementForUpdatingParameterInfo

public PsiAnnotationParameterList findElementForUpdatingParameterInfo(UpdateParameterInfoContext context)

Description copied from interface: ParameterInfoHandler

Hint has to be removed if method returns null.

Note: it is executed on non-UI thread

Specified by:

findElementForUpdatingParameterInfo in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

updateParameterInfo

public void updateParameterInfo(PsiAnnotationParameterList parameterOwner,
                                UpdateParameterInfoContext context)

Description copied from interface: ParameterInfoHandler

Updates parameter info context due to change of caret position.

It could update context and state of UpdateParameterInfoContext.getObjectsToView()

Note: context.getParameterOwner() equals to parameterOwner or null

Note: it is executed on non UI thread.

Specified by:

updateParameterInfo in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

updateUI

public void updateUI(PsiAnnotationMethod p,
                     ParameterInfoUIContext context)

Description copied from interface: ParameterInfoHandler

This method is executed on UI thread and supposed only to update UI representation using ParameterInfoUIContext.setUIComponentEnabled(boolean) or ParameterInfoUIContext.setupUIComponentPresentation(String, int, int, boolean, boolean, boolean, Color).

Don't perform any heavy calculations like resolve here: move it to ParameterInfoHandler.findElementForParameterInfo(CreateParameterInfoContext) or ParameterInfoHandler.updateParameterInfo(Object, UpdateParameterInfoContext).

Specified by:

updateUI in interface ParameterInfoHandler<PsiAnnotationParameterList,PsiAnnotationMethod>

updateUIText

public static java.lang.String updateUIText(PsiAnnotationMethod p,
                                            ParameterInfoUIContext context)
