org.wings.session .LowLevelEventDispatcher

LowLevelEventDispatcher
final public class LowLevelEventDispatcher implements java.io.Serializable(Code)
	Registers session component instants which want to receive low level events. The dispatcher holds a list of all known low level event listeners and is responsible to dispatch the according part of an original HTTP request to the LowLevelEventListener.processLowLevelEvent(StringString[]) method of the registered LowLevelEventListener s. author: Armin Haaf

Field Summary
protected boolean	namedEvents

Constructor Summary
public	LowLevelEventDispatcher()

Method Summary
final public void	addLowLevelEventListener(LowLevelEventListener gl, String eventId)
void	clear()
public boolean	dispatch(String name, String[] values) dispatch the events, encoded as [name/(multiple)values] in the HTTP request.
final public List	getLowLevelEventListener(String eventId) Returns list of registered low level event listener for the given event id. Parameters: eventId - The id (HTTP request parameter name) under which the listeners are registered.
public void	invokeLater(Runnable runnable)
void	invokeRunnables()
protected boolean	isEventEpochValid(LowLevelEventListener gl)
public void	register(LowLevelEventListener gl) Registers a low level event listeners (for HTTP request processing). The NamePrefix of the listeners id is used as HTTP requestr parameter name.
final public void	removeLowLevelEventListener(LowLevelEventListener gl, String eventId)
protected void	setEventEpoch(String epoch)
final public void	setNamedEvents(boolean registerListenerAlsoUnderName) Register low level event listeners additionally by their component name as event id. Used for purposes where you use fixed ids vs.
public void	unregister(LowLevelEventListener gl)

Field Detail

namedEvents
protected boolean namedEvents(Code)

Constructor Detail

LowLevelEventDispatcher
public LowLevelEventDispatcher()(Code)

Method Detail

addLowLevelEventListener
final public void addLowLevelEventListener(LowLevelEventListener gl, String eventId)(Code)

clear
void clear()(Code)

dispatch
public boolean dispatch(String name, String[] values)(Code)
	dispatch the events, encoded as [name/(multiple)values] in the HTTP request. the part in front of the UID_DIVIDER ('-') is removed, first. if the remainder contains an underscore ('_'), only the portion afore will be used to identify the target component. Parameters: name - Parameters: values - if the event has been dispatched

getLowLevelEventListener
final public List getLowLevelEventListener(String eventId)(Code)
	Returns list of registered low level event listener for the given event id. Parameters: eventId - The id (HTTP request parameter name) under which the listeners are registered. A list of registered low level event listener for the given event id.

invokeLater
public void invokeLater(Runnable runnable)(Code)

invokeRunnables
void invokeRunnables()(Code)

isEventEpochValid
protected boolean isEventEpochValid(LowLevelEventListener gl)(Code)

register
public void register(LowLevelEventListener gl)(Code)
	Registers a low level event listeners (for HTTP request processing). The NamePrefix of the listeners id is used as HTTP requestr parameter name. . Parameters: gl - listeners

removeLowLevelEventListener
final public void removeLowLevelEventListener(LowLevelEventListener gl, String eventId)(Code)

setEventEpoch
protected void setEventEpoch(String epoch)(Code)

setNamedEvents
final public void setNamedEvents(boolean registerListenerAlsoUnderName)(Code)
	Register low level event listeners additionally by their component name as event id. Used for purposes where you use fixed ids vs. dnymaically applied ids. Parameters: registerListenerAlsoUnderName - if `true` then components will also receieveHTTP values under their org.wings.SComponent.getNamein addition to org.wings.LowLevelEventListener.getLowLevelEventId

unregister
public void unregister(LowLevelEventListener gl)(Code)
