Interface AroundConstructCallback<T>

Type Parameters:

T - type the component class

public interface AroundConstructCallback<T>

An implementation of this interface may be registered with a WeldCreationalContext. Weld will then call the aroundConstruct(ConstructionHandle, AnnotatedConstructor, Object[], Map) method of the implementation during component creation, allowing an integrator to perform additional steps (e.g. invoking interceptors bound using the deployment descriptor) around component construction.

Method Summary

Modifier and Type	Method and Description
T	aroundConstruct(ConstructionHandle<T> handle, javax.enterprise.inject.spi.AnnotatedConstructor<T> constructor, Object[] parameters, Map<String,Object> data) The method is called during component creation, allowing an integrator to perform additional steps (e.g. invoking interceptors bound using the deployment descriptor) around component construction.

Method Detail

aroundConstruct

T aroundConstruct(ConstructionHandle<T> handle,
                  javax.enterprise.inject.spi.AnnotatedConstructor<T> constructor,
                  Object[] parameters,
                  Map<String,Object> data)
           throws Exception

The method is called during component creation, allowing an integrator to perform additional steps (e.g. invoking interceptors bound using the deployment descriptor) around component construction.

Parameters:

handle - the handle for controlling the component creation process and retrieving the created instance

constructor - a representation of the component constructor used for component creation

parameters - the parameters that will be passed to the component constructor. These parameters should be made available to AroundConstruct interceptors through the InvocationContext.getParameters() method. An implementation is free to modify the parameters or provide a different parameter array to the ConstructionHandle.

data - the context data associated with this AroundConstruct interception. The data should be made available to AroundConstruct interceptors through InvocationContext.getContextData(). An implementation is free to modify the map or to provide a different one to the ConstructionHandle.

Returns:

the created instance

Throws:

Exception - any underlying exception is propagated directly
