Constructor Detail

ClientProxyFactory

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

Method Detail

create

public T create(BeanInstance beanInstance)

Description copied from class: ProxyFactory

Method to create a new proxy that wraps the bean instance.

Overrides:

create in class ProxyFactory<T>

Parameters:

beanInstance - the bean instance

Returns:

a new proxy object

addAdditionalInterfaces

protected void addAdditionalInterfaces(Set<Class<?>> interfaces)

Description copied from class: ProxyFactory

Sub classes may override to specify additional interfaces the proxy should implement

Overrides:

addAdditionalInterfaces in class ProxyFactory<T>

addMethods

protected void addMethods(org.jboss.classfilewriter.ClassFile proxyClassType,
                          org.jboss.classfilewriter.ClassMethod staticConstructor)

Overrides:

addMethods in class ProxyFactory<T>

addFields

protected void addFields(org.jboss.classfilewriter.ClassFile proxyClassType,
                         List<DeferredBytecode> initialValueBytecode)

Overrides:

addFields in class ProxyFactory<T>

getMethodHandlerType

protected Class<? extends MethodHandler> getMethodHandlerType()

Overrides:

getMethodHandlerType in class ProxyFactory<T>

addSerializationSupport

protected void addSerializationSupport(org.jboss.classfilewriter.ClassFile proxyClassType)

Description copied from class: ProxyFactory

Adds special serialization code. By default this is a nop

Overrides:

addSerializationSupport in class ProxyFactory<T>

Parameters:

proxyClassType - the Javassist class for the proxy class

createForwardingMethodBody

protected void createForwardingMethodBody(org.jboss.classfilewriter.ClassMethod classMethod,
                                          MethodInformation methodInfo,
                                          org.jboss.classfilewriter.ClassMethod staticConstructor)

Calls methodHandler.invoke with a null method parameter in order to get the underlying instance. The invocation is then forwarded to this instance with generated bytecode.

Overrides:

createForwardingMethodBody in class ProxyFactory<T>

generateHashCodeMethod

protected void generateHashCodeMethod(org.jboss.classfilewriter.ClassFile proxyClassType)

Client proxies use the following hashCode: MyProxyName.class.hashCode()

Overrides:

generateHashCodeMethod in class ProxyFactory<T>

generateEqualsMethod

protected void generateEqualsMethod(org.jboss.classfilewriter.ClassFile proxyClassType)

Client proxies are equal to other client proxies for the same bean.

The corresponding java code: return other instanceof MyProxyClassType.class

Overrides:

generateEqualsMethod in class ProxyFactory<T>

Parameters:

proxyClassType - The class file

getProxyNameSuffix

protected String getProxyNameSuffix()

Description copied from class: ProxyFactory

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

isMethodAccepted

protected boolean isMethodAccepted(Method method,
                                   Class<?> proxySuperclass)

Overrides:

isMethodAccepted in class ProxyFactory<T>
