Method Detail

getNote

public final java.lang.Object getNote(int id)

setNote

public final void setNote(int id,
                          java.lang.Object o)

getType

public final int getType()

The id of the chain

setType

public final void setType(int i)

setLong

public final void setLong(int i,
                          long l)

getLong

public final long getLong(int i)

getWorkerEnv

public final WorkerEnv getWorkerEnv()

setWorkerEnv

public final void setWorkerEnv(WorkerEnv we)

getSource

public final JkChannel getSource()

setSource

public final void setSource(JkChannel ch)

getStatus

public final int getStatus()

setStatus

public final void setStatus(int s)

getNext

public final JkHandler getNext()

setNext

public final void setNext(JkHandler ch)

setRequest

public final void setRequest(Request req)

The high level request object associated with this context

getRequest

public final Request getRequest()

getMsg

public final Msg getMsg(int i)

The context may store a number of messages ( buffers + marshalling )

setMsg

public final void setMsg(int i,
                         Msg msg)

getConverter

public final C2BConverter getConverter()

setConverter

public final void setConverter(C2BConverter c2b)

isLogTimeEnabled

public final boolean isLogTimeEnabled()

getInputStream

public JkInputStream getInputStream()

getBuffer

public byte[] getBuffer(int id)

Each context contains a number of byte[] buffers used for communication. The C side will contain a char * equivalent - both buffers are long-lived and recycled. This will be called at init time. A long-lived global reference to the byte[] will be stored in the C context.

execute

public int execute()
            throws java.io.IOException

Invoke a java hook. The xEnv is the representation of the current execution environment ( the jni_env_t * )

Throws:

java.io.IOException

setJniEnv

public void setJniEnv(long xEnvP)

Store native execution context data when this handler is called from JNI. This will change on each call, represent temproary call data.

getJniEnv

public long getJniEnv()

setJniContext

public void setJniContext(long cContext)

The long-lived JNI context associated with this java context. The 2 share pointers to buffers and cache data to avoid expensive jni calls.

getJniContext

public long getJniContext()

getControl

public java.lang.Object getControl()

setControl

public void setControl(java.lang.Object control)

action

public void action(ActionCode actionCode,
                   java.lang.Object param)

Description copied from interface: ActionHook

Send an action to the connector.

Specified by:

action in interface ActionHook

Parameters:

actionCode - Type of the action

param - Action parameter

recycle

public void recycle()
