Class DynamicInterceptorStack

java.lang.Object
  net.sf.tie.ext.DynamicInterceptorStack

All Implemented Interfaces:

MethodInterceptorStack

public class DynamicInterceptorStack
extends Object
implements MethodInterceptorStack

A DynamicInterceptorStack uses a list of InterceptorFactory to build the interceptor stack for each required endPoint.

Constructor Summary

DynamicInterceptorStack()

Method Summary

void	addFactory(InterceptorFactory factory) Add a factory to the collection of factory to be consulted during a call to getInterceptors(Class, Object).
<T> Iterable<MethodInterceptor>	getInterceptors(Class<T> type, T endPoint) Consults the collection of InterceptorFactory instances to build an interception stack. The factories will be consulted in the order in which they are added - the first factory added will be the first one consulted, and any interceptor it creates will be at the top of the stack. A factory may return null if it does not have an interceptor to provide.

Method Detail

addFactory

public void addFactory(InterceptorFactory factory)

Add a factory to the collection of factory to be consulted during a call to getInterceptors(Class, Object). The factory collection follows the semantics of a List. A factory may be safely added twice if it is to be consulted twice during the execution of getInterceptors(Class, Object).

getInterceptors

public <T> Iterable<MethodInterceptor> getInterceptors(Class<T> type,
                                                       T endPoint)

Consults the collection of InterceptorFactory instances to build an interception stack.
The factories will be consulted in the order in which they are added - the first factory added will be the first one consulted, and any interceptor it creates will be at the top of the stack.
A factory may return null if it does not have an interceptor to provide.

Specified by:

getInterceptors in interface MethodInterceptorStack

Parameters:

type - The java type (typically an interface) which declares the methods to be intercepted.

endPoint - The java object that provides an implementation of those methods.

Returns:

A set of interceptors to apply over all invocations of methods on endPoint.
