Nested Class Summary

class

AbstractHandler.Loop The loop have to be started by the classes that extends AbstractHandler.

Field Summary

protected java.util.List	handlerList
java.util.Map	inProgressList list of request that are performed actualy
protected int	loopFrequency time (millis) the loop 'sleep' before looking for new requests or responses
protected int	loopTimeout maximal time a loop runs without existing a request or response to handle
protected java.util.List	requestList
protected java.util.List	responseList
protected int	responseTimeout maximal time (millis) the perfomrmance of a request is allowed to take
protected long	timestamp

Constructor Summary

AbstractHandler()

Method Summary

void	dispose()
boolean	fireRequest(OGCWebServiceEvent event) fires a request by notifiy all interested (responsible) Handler If for minimum one Handler was found that is responsible the method returns true otherwise false will be returned.
boolean	fireResponse(OGCWebServiceEvent event) fires a response by notifiy all interested (responsible) Handler If for minimum one Handler was found that is responsible the method returns true otherwise false will be returned.
void	registerHandler(Handler handler) registers a Handler so this Handler is able to act as a proxy to the registered handler
void	removeHandler(Handler handler)
void	setLoopFrequency(int millisec) sets the frequency/time a loop looks for new requests/responses to perform.
void	setLoopTimeout(int seconds) sets the time in seconds the handler keeps on running the request and response loops when no more requests or responses are registered to be performed.
void	setResponseTimeout(int seconds) sets time in seconds the waits for a response of a WMSService that serves a request (default: 2 seconds).
abstract void	stopLoops() stops the processing loop(s)

protected java.util.List responseList

inProgressList

public java.util.Map inProgressList

list of request that are performed actualy

protected long timestamp

Constructor Detail

AbstractHandler

public AbstractHandler()

Method Detail

dispose

public void dispose()

registerHandler

public void registerHandler(Handler handler)

registers a Handler so this Handler is able to act as a proxy to the registered handler

Specified by:

registerHandler in interface Handler

removeHandler

public void removeHandler(Handler handler)

Specified by:

removeHandler in interface Handler

registerHandler(Handler)

fireRequest

public boolean fireRequest(OGCWebServiceEvent event)

fires a request by notifiy all interested (responsible) Handler If for minimum one Handler was found that is responsible the method returns true otherwise false will be returned.

fireResponse

public boolean fireResponse(OGCWebServiceEvent event)

fires a response by notifiy all interested (responsible) Handler If for minimum one Handler was found that is responsible the method returns true otherwise false will be returned.

setResponseTimeout

public void setResponseTimeout(int seconds)

sets time in seconds the waits for a response of a WMSService that serves a request (default: 2 seconds).

setLoopTimeout

public void setLoopTimeout(int seconds)

sets the time in seconds the handler keeps on running the request and response loops when no more requests or responses are registered to be performed. A value of -1 (default) indicates that the loops will be stopped immidiatly if no more requests or responses are registered to be performed.

setLoopFrequency

public void setLoopFrequency(int millisec)

sets the frequency/time a loop looks for new requests/responses to perform.

stopLoops

public abstract void stopLoops()

stops the processing loop(s)
