Method Summary

Modifier and Type	Method and Description
static boolean	canConvertToLambda(PsiMethodReferenceExpression referenceExpression)
static boolean	canConvertToLambdaWithoutSideEffects(PsiMethodReferenceExpression methodReferenceExpression) Checks whether method reference can be converted to lambda without significant semantics change (i.e.
static PsiLambdaExpression	convertMethodReferenceToLambda(PsiMethodReferenceExpression referenceExpression, boolean ignoreCast, boolean simplifyToExpressionLambda)
static PsiExpression	convertToMethodCallInLambdaBody(PsiMethodReferenceExpression element)
static PsiLambdaExpression	createLambda(PsiMethodReferenceExpression referenceExpression, boolean doNotAddParameterTypes) Convert method reference to lambda if possible and return the created lambda without replacing original method reference.
static void	removeSideEffectsFromLambdaBody(Editor editor, PsiLambdaExpression lambdaExpression) Works for expression lambdas/one statement code block lambdas to ensures equivalent method ref -> lambda transformation.
static void	simplifyToExpressionLambda(PsiLambdaExpression lambdaExpression)

Method Detail

convertToMethodCallInLambdaBody

public static PsiExpression convertToMethodCallInLambdaBody(PsiMethodReferenceExpression element)

convertMethodReferenceToLambda

public static PsiLambdaExpression convertMethodReferenceToLambda(PsiMethodReferenceExpression referenceExpression,
                                                                 boolean ignoreCast,
                                                                 boolean simplifyToExpressionLambda)

canConvertToLambda

public static boolean canConvertToLambda(PsiMethodReferenceExpression referenceExpression)

createLambda

public static PsiLambdaExpression createLambda(PsiMethodReferenceExpression referenceExpression,
                                               boolean doNotAddParameterTypes)

Convert method reference to lambda if possible and return the created lambda without replacing original method reference.

Parameters:

referenceExpression - a method reference to convert

doNotAddParameterTypes - if false, parameter types could be added to the lambda to resolve ambiguity

Returns:

a created lambda or null if conversion fails

simplifyToExpressionLambda

public static void simplifyToExpressionLambda(PsiLambdaExpression lambdaExpression)

removeSideEffectsFromLambdaBody

public static void removeSideEffectsFromLambdaBody(Editor editor,
                                                   PsiLambdaExpression lambdaExpression)

Works for expression lambdas/one statement code block lambdas to ensures equivalent method ref -> lambda transformation.

canConvertToLambdaWithoutSideEffects

public static boolean canConvertToLambdaWithoutSideEffects(PsiMethodReferenceExpression methodReferenceExpression)

Checks whether method reference can be converted to lambda without significant semantics change (i.e. method reference qualifier has no side effects)

Parameters:

methodReferenceExpression - method reference to check

Returns:

true if method reference can be converted to lambda
