Method Detail

processDuplicates

public static void processDuplicates(PsiElement callElement,
                                     PsiElement generatedMethod,
                                     java.util.List<PsiElement> scope,
                                     SimpleDuplicatesFinder finder,
                                     Editor editor,
                                     Consumer<? super Pair<SimpleMatch,PsiElement>> replacer)

collectDuplicates

public static java.util.List<SimpleMatch> collectDuplicates(SimpleDuplicatesFinder finder,
                                                            java.util.List<PsiElement> searchScopes,
                                                            PsiElement generatedMethod)

Finds duplicates of the code fragment specified in the finder in given scopes. Note that in contrast to processDuplicates(com.intellij.psi.PsiElement, com.intellij.psi.PsiElement, java.util.List<com.intellij.psi.PsiElement>, com.intellij.refactoring.extractMethod.SimpleDuplicatesFinder, com.intellij.openapi.editor.Editor, com.intellij.util.Consumer<? super com.intellij.openapi.util.Pair<com.intellij.refactoring.extractMethod.SimpleMatch, com.intellij.psi.PsiElement>>) the search is performed synchronously because normally you need the results in order to complete the refactoring. If user cancels it, empty list will be returned.

Parameters:

finder - finder object to seek for duplicates

searchScopes - scopes where to look them in

generatedMethod - new method that should be excluded from the search

Returns:

list of discovered duplicate code fragments or empty list if user interrupted the search

replaceDuplicates

public static void replaceDuplicates(PsiElement callElement,
                                     Editor editor,
                                     Consumer<? super Pair<SimpleMatch,PsiElement>> replacer,
                                     java.util.List<? extends SimpleMatch> duplicates)

Notifies user about found duplicates and then highlights each of them in the editor and asks user how to proceed.

Parameters:

callElement - generated expression or statement that contains invocation of the new method

editor - instance of editor where refactoring is performed

replacer - strategy of substituting each duplicate occurence with the replacement fragment

duplicates - discovered duplicates of extracted code fragment
