getInstance

public static InterceptorChainFactory getInstance()

buildInterceptorChain

public Interceptor buildInterceptorChain(CacheImpl cache)
                                  throws java.lang.IllegalAccessException,
                                         java.lang.ClassNotFoundException,
                                         java.lang.InstantiationException

Throws:

java.lang.IllegalAccessException

java.lang.ClassNotFoundException

java.lang.InstantiationException

setLastInterceptorPointer

public Interceptor setLastInterceptorPointer(Interceptor first,
                                             Interceptor last)

printInterceptorChain

public java.lang.String printInterceptorChain(Interceptor i)

asList

public java.util.List<Interceptor> asList(Interceptor interceptor)

correctInterceptorChaining

public Interceptor correctInterceptorChaining(java.util.List<Interceptor> interceptors)

"Fixes" the next() and last() pointers for each interceptor, based on the order presented in the list passed in

Parameters:

interceptors -

Returns:

the first interceptor in the chain.

initialiseInterceptors

public void initialiseInterceptors(Interceptor firstInterceptor,
                                   CacheSPI cache)

Initialises the interceptors with a CacheSPI instance. Essentially calls setCache(). This is done AFTER the interceptor chain is created, and when Cache.start() is called, so the interceptors get a fully initialised cache.

Parameters:

chain - interceptor chain

cache - cache instance
