InterceptedSubclassFactory

public InterceptedSubclassFactory(String contextId,
                          Class<?> proxiedBeanType,
                          Set<? extends Type> typeClosure,
                          Bean<?> bean,
                          Set<MethodSignature> enhancedMethodSignatures)

InterceptedSubclassFactory

public InterceptedSubclassFactory(String contextId,
                          Class<?> proxiedBeanType,
                          Set<? extends Type> typeClosure,
                          String proxyName,
                          Bean<?> bean,
                          Set<MethodSignature> enhancedMethodSignatures)

Creates a new proxy factory when the name of the proxy class is already known, such as during de-serialization

Parameters:

proxiedBeanType - the super-class for this proxy class

typeClosure - the bean types of the bean

enhancedMethodSignatures - a restricted set of methods that need to be intercepted

Method Detail

getProxyNameSuffix

protected String getProxyNameSuffix()

Returns a suffix to append to the name of the proxy class. The name already consists of _$$_Weld, to which the suffix is added. This allows the creation of different types of proxies for the same class.

Overrides:

getProxyNameSuffix in class ProxyFactory<T>

Returns:

a name suffix

addMethods

protected void addMethods(ClassFile proxyClassType)

Overrides:

addMethods in class ProxyFactory<T>

addMethodsFromClass

protected void addMethodsFromClass(ClassFile proxyClassType)

Overrides:

addMethodsFromClass in class ProxyFactory<T>

createForwardingMethodBody

protected void createForwardingMethodBody(ClassMethod classMethod,
                              MethodInformation method)

Overrides:

createForwardingMethodBody in class ProxyFactory<T>

createInterceptorBody

protected void createInterceptorBody(ClassMethod method,
                         MethodInformation methodInfo,
                         boolean delegateToSuper)

Creates the given method on the proxy class where the implementation forwards the call directly to the method handler.

the generated bytecode is equivalent to:

return (RetType) methodHandler.invoke(this,param1,param2);

Parameters:

methodInfo - any JLR method

delegateToSuper -

invokeMethodHandler

protected static void invokeMethodHandler(ClassMethod method,
                       MethodInformation methodInfo,
                       boolean addReturnInstruction,
                       BytecodeMethodResolver bytecodeMethodResolver,
                       boolean addProceed)

calls methodHandler.invoke for a given method

Parameters:

methodInfo - declaring class of the method

addReturnInstruction - set to true you want to return the result of

bytecodeMethodResolver - The method resolver

addProceed -

addSpecialMethods

protected void addSpecialMethods(ClassFile proxyClassType)

Adds methods requiring special implementations rather than just delegation.

Overrides:

addSpecialMethods in class ProxyFactory<T>

Parameters:

proxyClassType - the Javassist class description for the proxy type

getBeanType

public Class<?> getBeanType()

Overrides:

getBeanType in class ProxyFactory<T>

isCreatingProxy

protected boolean isCreatingProxy()

Overrides:

isCreatingProxy in class ProxyFactory<T>
