Package org.jboss.weld.bean.proxy

Class DecoratorProxyFactory<T>

java.lang.Object

org.jboss.weld.bean.proxy.ProxyFactory<T>

org.jboss.weld.bean.proxy.DecoratorProxyFactory<T>

All Implemented Interfaces:

PrivilegedAction<T>

public class DecoratorProxyFactory<T>
extends ProxyFactory<T>

This special proxy factory is mostly used for abstract decorators. When a delegate field is injected, the abstract methods directly invoke the corresponding method on the delegate. All other cases forward the calls to the BeanInstance for further processing.

Method Detail

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>

addMethodsFromClass

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

Overrides:

addMethodsFromClass in class ProxyFactory<T>

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

isUsingProxyInstantiator

protected boolean isUsingProxyInstantiator()

Overrides:

isUsingProxyInstantiator in class ProxyFactory<T>

Returns:

true if ProxyInstantiator is used to instantiate proxy instances
