Method Detail

isApplicableForSource

public boolean isApplicableForSource(PsiElement sourceClass)

Description copied from class: PushDownDelegate

Check if delegate can process pushed members from the sourceClass. It is used to find appropriate delegate to process pushing from source class to target PushDownDelegate.findDelegateForTarget(PsiElement, PsiElement). Implementations are supposed to override this method when overriding default behaviour for the language, e.g. pushing members from groovy class to java, groovy could provide additional delegate which inherits delegate for java and accepts groovy sources. Methods to process target class should be updated to cope with source of another language (e.g. calling super on PushDownData translated to java): PushDownDelegate.checkTargetClassConflicts(PsiElement, PushDownData, MultiMap, NewSubClassData), PushDownDelegate.pushDownToClass(PsiElement, PushDownData)

Specified by:

isApplicableForSource in class PushDownDelegate<MemberInfo,PsiMember>

findInheritors

public java.util.List<PsiElement> findInheritors(PushDownData<MemberInfo,PsiMember> pushDownData)

Description copied from class: PushDownDelegate

Find classes to push members down.

Specified by:

findInheritors in class PushDownDelegate<MemberInfo,PsiMember>

checkSourceClassConflicts

public void checkSourceClassConflicts(PushDownData<MemberInfo,PsiMember> pushDownData,
                                      MultiMap<PsiElement,java.lang.String> conflicts)

Description copied from class: PushDownDelegate

Collect conflicts inside sourceClass assuming members would be removed, e.g. check if members remaining in source class do not depend on moved members

Specified by:

checkSourceClassConflicts in class PushDownDelegate<MemberInfo,PsiMember>

checkTargetClassConflicts

public void checkTargetClassConflicts(PsiElement targetClass,
                                      PushDownData<MemberInfo,PsiMember> pushDownData,
                                      MultiMap<PsiElement,java.lang.String> conflicts,
                                      NewSubClassData subClassData)

Description copied from class: PushDownDelegate

Collect conflicts inside targetClass assuming methods would be pushed, e.g. check if target class already has field with the same name, some references types won't be accessible anymore, etc If targetClass == null (target class should be created), then subClassData would be not null

Specified by:

checkTargetClassConflicts in class PushDownDelegate<MemberInfo,PsiMember>

preprocessNoInheritorsFound

public NewSubClassData preprocessNoInheritorsFound(PsiElement sourceClass,
                                                   java.lang.String conflictDialogTitle)

Description copied from class: PushDownDelegate

Called if no inheritors were found in PushDownDelegate.findInheritors(PushDownData). Should warn that members would be deleted and suggest to create new target class if applicable

Overrides:

preprocessNoInheritorsFound in class PushDownDelegate<MemberInfo,PsiMember>

Returns:

NewSubClassData.ABORT_REFACTORING if refactoring should be aborted null to proceed without inheritors (members would be deleted from the source class and not added to the target) new NewSubClassData(context, name) if new inheritor should be created with PushDownDelegate.createSubClass(PsiElement, NewSubClassData)

prepareToPush

public void prepareToPush(PushDownData<MemberInfo,PsiMember> pushDownData)

Description copied from class: PushDownDelegate

Could be used e.g. to encode mutual references between moved members

Overrides:

prepareToPush in class PushDownDelegate<MemberInfo,PsiMember>

pushDownToClass

public void pushDownToClass(PsiElement targetElement,
                            PushDownData<MemberInfo,PsiMember> pushDownData)

Description copied from class: PushDownDelegate

Push members to the target class adjusting visibility, comments according to the policy, etc

Specified by:

pushDownToClass in class PushDownDelegate<MemberInfo,PsiMember>

inlineSuperCall

public void inlineSuperCall(MemberInfoBase<? extends PsiElement> memberInfo,
                            PsiMethod methodBySignature)

removeFromSourceClass

public void removeFromSourceClass(PushDownData<MemberInfo,PsiMember> pushDownData)

Description copied from class: PushDownDelegate

Remove members from the source class according to the abstract flag.

Specified by:

removeFromSourceClass in class PushDownDelegate<MemberInfo,PsiMember>

createSubClass

public PsiElement createSubClass(PsiElement aClass,
                                 NewSubClassData subClassData)

Description copied from class: PushDownDelegate

Create sub class with subClassData.getNewClassName() in the specified context if no inheritors were found

Overrides:

createSubClass in class PushDownDelegate<MemberInfo,PsiMember>
