Constructor Details

AopProxyWriter

public AopProxyWriter(ClassElement targetType,
 BeanDefinitionWriter parent,
 OptionalValues<Boolean> settings,
 VisitorContext visitorContext,
 AnnotationValue<?>... interceptorBinding)

Constructs a new AopProxyWriter for the given parent BeanDefinitionWriter and starting interceptors types.

Additional Interceptor types can be added downstream with ProxyingBeanDefinitionWriter.visitInterceptorBinding(AnnotationValue[]) .

Parameters:

targetType - The classElement

parent - The parent BeanDefinitionWriter

settings - optional setting

visitorContext - The visitor context

interceptorBinding - The interceptor binding of the Interceptor instances to be injected

AopProxyWriter

public AopProxyWriter(ClassElement targetType,
 ClassElement[] interfaceTypes,
 VisitorContext visitorContext,
 AnnotationValue<?>... interceptorBinding)

Constructs a new AopProxyWriter for the purposes of writing Introduction advise.

Parameters:

targetType - The source element

interfaceTypes - The additional interfaces to implement

visitorContext - The visitor context

interceptorBinding - The interceptor types

AopProxyWriter

public AopProxyWriter(ClassElement targetType,
 boolean implementInterface,
 ClassElement[] interfaceTypes,
 VisitorContext visitorContext,
 AnnotationValue<?>... interceptorBinding)

Constructs a new AopProxyWriter for the purposes of writing Introduction advise.

Parameters:

targetType - The source element

implementInterface - Whether the interface should be implemented. If false the interfaceTypes argument should contain at least one entry

interfaceTypes - The additional interfaces to implement

visitorContext - The visitor context

interceptorBinding - The interceptor binding

Method Details

createIntroductionProxyBeanDefinitionWriter

protected BeanDefinitionWriter createIntroductionProxyBeanDefinitionWriter(String suffix)

Specified by:

createIntroductionProxyBeanDefinitionWriter in class ProxyingBeanDefinitionWriter

Parameters:

suffix - The name suffix

Returns:
