Yeni bir güneş tutulması yeniden başlatıyorum. Bu geliştiriciler-Çek önkoşulları ana yöntem için çocuk bir yöntem ifadesini sağlayacaktır.

Bu "Hayır" Düzenle sağlanan hedef. "hatası alıyorum" Önizleme seçtiğimde "yeniden düzenleme Sihirbazı, ama Bitirmek seçtiğimde mükemmel çalışıyor Bu TextEdit ASTRewrite.rewriteAST() döndürülen bir sorun neden gibi görünüyor. Ancak nedenini çözemedim bir türlü.

Yığın Özel Durum İzleme Refactoring.createChange() benim kod çalıştırmak ve değiştirmek önizleme oluşturmak için kullanılır sonra olur.

Şu anda değişiklik yapan kod bu gibi görünüyor:

CompilationUnit sourceNode = ...
ASTRewrite sourceRewrite = ASTRewrite.create(sourceNode.getAST());

Statement statement = ...
sourceRewrite.createMoveTarget(statement);

CompilationUnit destinationNode = ...
MethodDeclaration destinationMethod = ...
ASTRewrite destinationRewrite = ASTRewrite.create(destinationNode.getAST());

ListRewrite lrw = destinationRewrite.getListRewrite(destinationMethod.getBody(),
    Block.STATEMENTS_PROPERTY);

lrw.insertFirst(statement, null);

Biliyorum o yolu createMoveTarget kullanılmaz nasıl belgelenmiştir, ama ne zaman I takip belgeleri aşağıdaki gibi bu söylem silinmiş kaynağı değil taşındı hedef ve hala aynı hata içinde önizleme.

CompilationUnit sourceNode = ...
ASTRewrite sourceRewrite = ASTRewrite.create(sourceNode.getAST());

Statement statement = ...
Statement replacement = sourceRewrite.createMoveTarget(statement);
sourceRewrite.remove(statement, null);

CompilationUnit destinationNode = ...
MethodDeclaration destinationMethod = ...
ASTRewrite destinationRewrite = ASTRewrite.create(destinationNode.getAST());

ListRewrite lrw = destinationRewrite.getListRewrite(destinationMethod.getBody(),
    Block.STATEMENTS_PROPERTY);

lrw.insertFirst(replacement, null);

Burada yeniden Düzenleme gerçekleştirildiği bir örnek.

Daha önce:

class A {
    foo(int a) {
        return a * 2;
    }
}

class B {
    foo(int a) {
        JC.requires(a > 1);

        return a * 3;
    }
}

Sonra:

class A {
    foo(int a) {
        JC.requires(a > 1);

        return a * 2;
    }
}

class B extends A {
    foo(int a) {        
        return a * 3;
    }
}

John, AccelerEyes kurucusu tarafından bir konuşma katılan zevk oldu. Onlar sadece kötü yazılmış kod kaldırıldı ve birkaç bit kaydedilmiş kod ile değiştirilir orada burada çünkü hızlanma alamadım. Onların hızlanma çoğunlukla önbellek durumu istismar ve bellek işlemleri çok şey (GPU). Matlab eğer yanlış hatırlamıyorsam GPU ve CPU arasında veri aktarımı dayanıyordu, ve bu nedenle hızlanma deli oldu.
