Constructor Detail

JkHandler

public JkHandler()
Method Detail

setWorkerEnv

public void setWorkerEnv(WorkerEnv we)

setName

public void setName(java.lang.String s)
Set the name of the handler. Will allways be called by worker env after creating the worker.


getName

public java.lang.String getName()

setId

public void setId(int id)
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 )


getId

public int getId()

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(java.lang.String s)

getNext

public java.lang.String getNext()

init

public void init()
          throws java.io.IOException
Should register the request types it can handle, same style as apache2.

Throws:
java.io.IOException

destroy

public void destroy()
             throws java.io.IOException
Clean up and stop the handler

Throws:
java.io.IOException

createMsgContext

public MsgContext createMsgContext()

createMsgContext

public MsgContext createMsgContext(int bsize)

invoke

public int invoke(Msg msg,
                  MsgContext mc)
           throws java.io.IOException
Throws:
java.io.IOException

setProperty

public void setProperty(java.lang.String name,
                        java.lang.String value)

getProperty

public java.lang.String getProperty(java.lang.String name)

addHandlerCallback

public void addHandlerCallback(JkHandler w)
Experimental, will be replaced. This allows handlers to be notified when other handlers are added.


handleNotification

public void handleNotification(javax.management.Notification notification,
