java.lang.Object org.jboss.cache.interceptors.InterceptorChain
public class InterceptorChain
Knows how to build and manage an chain of interceptors. Also in charge with invoking methods on the chain.
Constructor Summary | |
---|---|
InterceptorChain(CommandInterceptor first)
Constructs an interceptor chain having the supplied interceptor as first. |
Method Summary | |
---|---|
boolean |
addAfterInterceptor(CommandInterceptor toAdd,
Class<? extends CommandInterceptor> afterInterceptor)
Adds a new interceptor in list after an interceptor of a given type. |
boolean |
addBeforeInterceptor(CommandInterceptor toAdd,
Class<? extends CommandInterceptor> beforeInterceptor)
Adds a new interceptor in list after an interceptor of a given type. |
void |
addInterceptor(CommandInterceptor interceptor,
int position)
Inserts the given interceptor at the specified position in the chain (o based indexing). |
void |
appendIntereceptor(CommandInterceptor ci)
Appends at the end. |
List<CommandInterceptor> |
asList()
Returns an unmofiable list with all the interceptors in sequence. |
boolean |
containsInstance(CommandInterceptor interceptor)
Checks whether the chain contains the supplied interceptor instance. |
CommandInterceptor |
getFirstInChain()
|
String |
getInterceptorDetails()
|
String |
getInterceptorDetailsAsHtml()
|
List<CommandInterceptor> |
getInterceptorsWhichExtend(Class<? extends CommandInterceptor> interceptorClass)
Returns all interceptors which extend the given command interceptor. |
List<CommandInterceptor> |
getInterceptorsWithClassName(String fqName)
Returns all the interceptors that have the fully qualified name of their class equal with the supplied class name. |
InvocationContext |
getInvocationContext()
|
void |
initialize(InvocationContextContainer invocationContextContainer)
|
Object |
invoke(InvocationContext ctx,
VisitableCommand command)
Walks the command through the interceptor chain. |
Object |
invoke(VisitableCommand cacheCommand)
Similar to invoke(org.jboss.cache.InvocationContext , org.jboss.cache.commands.VisitableCommand) , but
constructs a invocation context on the fly, using ThreadLocal.get() and setting the origin local flag to its default value. |
Object |
invokeRemote(VisitableCommand cacheCommand)
Similar to invoke(org.jboss.cache.InvocationContext , org.jboss.cache.commands.VisitableCommand) , but
constructs a invocation context on the fly, using ThreadLocal.get() |
void |
removeInterceptor(Class<? extends CommandInterceptor> clazz)
Removes all the occurences of supplied interceptor type from the chain. |
void |
removeInterceptor(int position)
Removes the interceptor at the given postion. |
void |
setFirstInChain(CommandInterceptor interceptor)
Mainly used by unit tests to replace the interceptor chain with the starting point passed in. |
int |
size()
Returns the number of interceptors in the chain. |
String |
toString()
|
