Constructor Detail

ClientProxyFactory

public ClientProxyFactory(Class<?> proxiedBeanType,
                  Set<? extends Type> typeClosure,
                  javax.enterprise.inject.spi.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

addFields

protected void addFields(javassist.bytecode.ClassFile proxyClassType,
             javassist.bytecode.Bytecode initialValueBytecode)

Overrides:

addFields in class ProxyFactory<T>

addSerializationSupport

protected void addSerializationSupport(javassist.bytecode.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 javassist.bytecode.Bytecode createForwardingMethodBody(javassist.bytecode.ClassFile file,
                                                     MethodInformation methodInfo)
                                                          throws javassist.NotFoundException

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>

Throws:

javassist.NotFoundException

generateHashCodeMethod

protected javassist.bytecode.MethodInfo generateHashCodeMethod(javassist.bytecode.ClassFile proxyClassType)

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

Overrides:

generateHashCodeMethod in class ProxyFactory<T>

generateEqualsMethod

protected javassist.bytecode.MethodInfo generateEqualsMethod(javassist.bytecode.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
