tryToInlineArrayCreationForVarargs

public static void tryToInlineArrayCreationForVarargs(PsiExpression expr)

inlineArrayCreationForVarargs

public static void inlineArrayCreationForVarargs(PsiNewExpression arrayCreation)

allUsagesAreTailCalls

public static boolean allUsagesAreTailCalls(PsiMethod method)

getTailCallType

public static InlineUtil.TailCallType getTailCallType(PsiReference psiReference)

substituteTypeParams

public static void substituteTypeParams(PsiElement scope,
                                        PsiSubstitutor substitutor,
                                        PsiElementFactory factory)

                                       throws IncorrectOperationException

Throws:

IncorrectOperationException

isChainingConstructor

public static boolean isChainingConstructor(PsiMethod constructor)

checkChangedBeforeLastAccessConflicts

public static void checkChangedBeforeLastAccessConflicts(MultiMap<PsiElement,java.lang.String> conflicts,
                                                         PsiExpression initializer,
                                                         PsiVariable variable)

Extracts all references from initializer and checks whether referenced variables are changed after variable initialization and before last usage of variable. If so, referenced value change returned with appropriate error message.

Parameters:

conflicts - map for found conflicts

initializer - variable initializer

extractReturnValues

public static void extractReturnValues(PsiMethod method,
                                       boolean replaceWithContinue)

Extracts side effects from return statements, replacing them with simple return; or continue; while preserving semantics.

Parameters:

method - method to process

replaceWithContinue - if true, returns will be replaced with continue.

inlineInitializer

public static PsiExpression inlineInitializer(PsiVariable variable,
                                              PsiExpression initializer,

                                    throws IncorrectOperationException

Try to inline local variable which was generated during method inlining (e.g. to hold a parameter or this reference)

Parameters:

variable - variable to inline

strictlyFinal - whether the variable is referenced in the places where final variable is required

Throws:

IncorrectOperationException

tryInlineResultVariable

public static void tryInlineResultVariable(PsiLocalVariable resultVar,
                                           PsiReferenceExpression resultUsage)
                                    throws IncorrectOperationException

Try to inline the result variable after method inlining

Parameters:

resultVar - variable to inline

resultUsage - variable usage

Throws:

IncorrectOperationException
