Class RelaySI

java.lang.Object
  Relay
      RelaySI

All Implemented Interfaces:

EventListener

Direct Known Subclasses:

RelaySIP

public abstract class RelaySI
extends Relay

A synchronous relay, based on an intermediate JavaScript listener/relay [but with bugs] The JavaScript side listener/relay pushes events out to the Java side.

Suffers same bugs as RelayS. Try RelaySIP, instead.

Nested Class Summary

class

RelaySI.DispatchAdaptor Relay adaptor that wraps each event from the JavaScript side, as a proper Java Event.

Field Summary

(package private) Object	dispatchAdaptor Called from JavaScript side when event occurs.
static String	HANDLE_EVENT_SCRIPT Implementation of rhiRelay listener, expressed as a script fragment.
(package private) Rhinohide	rhiRelay The listener/relay on the JavaScript side.

Constructor Summary

RelaySI()
Creates a RelaySI.

RelaySI(boolean dummyFlag)
Creates a modified RelaySI.

Method Summary

(package private) void	addTo(RhiEventTarget target, String type, boolean useCapture) Adds a JavaScript relay to the specified target, as a listener.
(package private) netscape.javascript.JSObject	createJSORelay_orNull(RhiWindow window)
(package private) void	removeFrom(RhiEventTarget target, String type, boolean useCapture) Removes this relay from the specified target.

Field Detail

dispatchAdaptor

Object dispatchAdaptor

Called from JavaScript side when event occurs. Wraps it as Java DOM Event, and forwards it to EventListener.this.

rhiRelay

Rhinohide rhiRelay

The listener/relay on the JavaScript side. It's a free object on that side, subject to garbage collection, so it should cleanly evaporate when we're done with it.

HANDLE_EVENT_SCRIPT

public static final String HANDLE_EVENT_SCRIPT

Implementation of rhiRelay listener, expressed as a script fragment. [This will later be made private.]

RelaySI

public RelaySI()

Creates a RelaySI.

RelaySI

RelaySI(boolean dummyFlag)

Creates a modified RelaySI.

Parameters:

dummyFlag - ignored, serves only to discriminate constructor

Method Detail

createJSORelay_orNull

@ThreadSafe
netscape.javascript.JSObject createJSORelay_orNull(RhiWindow window)

addTo

@ThreadSafe
void addTo(RhiEventTarget target,
                      String type,
                      boolean useCapture)
     throws StubbornRhinoException

Adds a JavaScript relay to the specified target, as a listener. The JavaScript relay pushes events out to this Java relay, which then wraps them and passes them on to the Java listener.

Specified by:

addTo in class Relay

Throws:

StubbornRhinoException

removeFrom

@ThreadSafe
void removeFrom(RhiEventTarget target,
                           String type,
                           boolean useCapture)
