Constructor Detail

ProxyMethodHandler

public ProxyMethodHandler(String contextId,
                          BeanInstance beanInstance,
                          Bean<?> bean)

Method Detail

getContextualInstance

public Object getContextualInstance()

Description copied from interface: WeldClientProxy.Metadata

Retrieve the current contextual instance associated with the current context for this client proxy. Note that in some cases the contextual instance is still an instance of WeldConstruct.

Specified by:

getContextualInstance in interface WeldClientProxy.Metadata

Returns:

the underlying contextual instance of this client proxy instance.

invoke

public Object invoke(Object self,
                     Method thisMethod,
                     Method proceed,
                     Object[] args)
              throws Throwable

Description copied from interface: MethodHandler

Is called when a method is invoked on a proxy instance associated with this handler. This method must process that method invocation.

Specified by:

invoke in interface MethodHandler

Parameters:

self - the proxy instance.

thisMethod - the overridden method declared in the super class or interface.

proceed - the forwarder method for invoking the overridden method. It is null if the overridden method is abstract or declared in the interface.

args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance. If a parameter type is a primitive type, the type of the array element is a wrapper class.

Returns:

the resulting value of the method invocation.

Throws:

Throwable - if the method invocation fails.

getBean

public Bean<?> getBean()

Description copied from interface: WeldClientProxy.Metadata

Retrieve Bean metadata for this proxy instance.

Specified by:

getBean in interface WeldClientProxy.Metadata

Returns:

Bean metadata for this proxy

getInstance

public Object getInstance()

Returns the underlying instance.

Returns:

the underlying instance
