name

protected String name

protected JkHandler next

Method Detail

addHandlerCallback

public void addHandlerCallback(JkHandler w)

Experimental, will be replaced. This allows handlers to be notified when other handlers are added.

createMsgContext

public MsgContext createMsgContext(int bsize)

destroy

public void destroy()

Clean up and stop the handler

handleNotification

public void handleNotification(Notification notification, Object handback)

init

public void init()

Should register the request types it can handle, same style as apache2.

invoke

public int invoke(Msg msg, MsgContext mc)

postRegister

public void postRegister(Boolean registrationDone)

preRegister

public ObjectName preRegister(MBeanServer server, ObjectName oname)

Set the id of the worker. We use an id for faster dispatch. Since we expect a decent number of handler in system, the id is unique - that means we may have to allocate bigger dispatch tables. ( easy to fix if needed )

setName

public void setName(String s)

Set the name of the handler. Will allways be called by worker env after creating the worker.

setNext

public void setNext(JkHandler h)

Catalina-style "recursive" invocation. A chain is used for Apache/3.3 style iterative invocation.

setNext

public void setNext(String s)

setProperty

public void setProperty(String name, String value)

setWorkerEnv

public void setWorkerEnv(WorkerEnv we)
