Constructor Detail

RemoteHttpContextFactory

public RemoteHttpContextFactory(HttpRequest req,
                                HttpResponse res)

Method Detail

addNew

public static IContextFactory addNew(HttpRequest req,
                                     HttpResponse res,
                                     IContextFactoryVisitor impl)

Create and add a new ContextFactory.

Parameters:

req - The HttpRequest

res - The HttpResponse

Returns:

The created ContextFactory

getId

public java.lang.String getId()

Return the serializable ID of the context factory

Specified by:

getId in interface IContextFactory

Returns:

The ID

initialize

public void initialize()

Called when the context runner starts

Specified by:

initialize in interface IContextFactory

See Also:

IContextFactory.releaseManaged(), IJavaBridgeFactory.destroy()

invalidate

public void invalidate()

Hook is called at the end of the life cycle. Either from destroy(), recycle() or from destroyOrphaned().

Specified by:

invalidate in interface IJavaBridgeFactory

Overrides:

invalidate in class SessionFactory

See Also:

IJavaBridgeFactory.destroy(), IJavaBridgeFactory.recycle()

recycle

public void recycle(java.lang.String id)

Update the context factory with the new JavaBridge obtained from the servlet

Specified by:

recycle in interface IContextFactory

Parameters:

id - The fresh id

See Also:

ContextFactory.recycle(), Request.setBridge(php.java.bridge.JavaBridge), Request.recycle()

release

public void release()

Releases the context factory. This method should be called when the factory is not needed anymore. Implementations could then remove any unused context factory from the classloader's list of context factories.

Specified by:

release in interface IContextFactory

releaseManaged

public void releaseManaged()
                    throws java.lang.InterruptedException

Wait until this context is finished and release/destroy it. This method returns immediately if this context is not in use yet or it is no longer in use. Call this method only if Java has initiated the communication and Java have full control over the connection, for example via a ScriptEngine's URLReader or CGIRunner. For Apache/PHP initiated requests use a combination of #waitFor(long) and #release() instead.

Specified by:

releaseManaged in interface IContextFactory

Throws:

java.lang.InterruptedException

See Also:

ContextRunner

waitFor

public void waitFor(long timeout)
             throws java.lang.InterruptedException

Wait until this context is finished.

Specified by:

waitFor in interface IContextFactory

Parameters:

timeout - The timeout

Throws:

java.lang.InterruptedException

See Also:

ContextRunner

parseHeader

public void parseHeader(Request req,
                        java.io.InputStream in)
                 throws java.io.IOException

Called for the request header

Specified by:

parseHeader in interface IJavaBridgeFactory

Overrides:

parseHeader in class JavaBridgeFactory

Parameters:

req - the current request

in - the input stream

Throws:

java.io.IOException

setContext

public void setContext(IContext context)

Set the Context into this factory. Should be called by Context.addNew() only.

Specified by:
