ValidationMainThread

public abstract class GenericValidationThread
extends java.lang.Thread

Obecny predchudce vlaken, ktera se pouzivaji pro validaci. Umi se spustit a ohlidat dobu spusteni, napriklad. Dale obsahuje staticke metody, ktere umoznuji zjistit validacni domenu, info a dalsi veci aktualniho vlakna. User: Lukas Date: 18.4.2007 Time: 11:55:40

GenericValidationThread(FullValidationResult result)

Method Summary

static ValidationDomain	getActualDomain() Vrati aktualni validacni domenu - vezme aktualni vlakno a pokud se jedna o GenericValidationThread, vrati domenu.
static FullValidationResult	getActualResult() Vrati aktualni ValidationResult - vezme aktualni vlakno a pokud se jedna o GenericValidationThread, vrati result.
private TimeLimitedStackItem	getActualStackItem() Vrati do jakeho casoveho okamziku se nyni ceka.
java.lang.Throwable	getExitReason()
private long	getNowWaitingToTime() Vrati do jakeho casoveho okamziku se nyni ceka.
void	popTimeLimitedBlock()
void	pushTimeLimitedBlock(long maxMiliseconds, java.lang.String exceededKey) Pokud se vstupuje do time-limited bloku procesu, tak se vola tohle (na jiz bezicim vlakne).
void	run() Tahle metoda je zdedena a odchytava ValidationError a predava ho volajicimu (respektive uklada to do resultu a konci - volajici si musi zkontrolovat, zda nedoslo k chybe).
boolean	runForLimitedTime(long maxMiliseconds, java.lang.String timeoutKey) Metoda spusti toto vlakno (je tedy volana z VNE vlakna) a necha ho bezet pouze zadany pocet milisekund.
protected abstract void	runValidation()

Method Detail

getExitReason

public java.lang.Throwable getExitReason()

setExitReason

protected void setExitReason(java.lang.Throwable exitReason)

run

public final void run()

Tahle metoda je zdedena a odchytava ValidationError a predava ho volajicimu (respektive uklada to do resultu a konci - volajici si musi zkontrolovat, zda nedoslo k chybe). Zdedene tridy at si zdedi metodu 'runValidation()'

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

runValidation

protected abstract void runValidation()

pushTimeLimitedBlock

public void pushTimeLimitedBlock(long maxMiliseconds,
                                 java.lang.String exceededKey)

Pokud se vstupuje do time-limited bloku procesu, tak se vola tohle (na jiz bezicim vlakne). zajisti to to, ze cekani na ukonceni vlakna (ktere je v teto chvili blokovano v 'runForLimitedTime') bude trvat jinou dobu.

Po opusteni bloku je treba volat 'popTimeLimitedBlock'.

Parameters:

maxMiliseconds -

exceededKey -

popTimeLimitedBlock

public void popTimeLimitedBlock()

getNowWaitingToTime

private long getNowWaitingToTime()

Vrati do jakeho casoveho okamziku se nyni ceka. Synchronizovano.

Returns:

getActualStackItem

private TimeLimitedStackItem getActualStackItem()

Vrati do jakeho casoveho okamziku se nyni ceka. Synchronizovano.

Returns:

runForLimitedTime

public boolean runForLimitedTime(long maxMiliseconds,
                                 java.lang.String timeoutKey)
                          throws java.lang.Throwable

Metoda spusti toto vlakno (je tedy volana z VNE vlakna) a necha ho bezet pouze zadany pocet milisekund. Pokud vlakno do te doby skonci, je vse ok a vraci TRUE. Pokud neskonci, je nasilne ukonceno, vypise se chyba do 'validationResultu' a vraci FALSE.

Parameters:

maxMiliseconds -

Returns:

Throws:

java.lang.Throwable

getActualDomain

public static ValidationDomain getActualDomain()

Vrati aktualni validacni domenu - vezme aktualni vlakno a pokud se jedna o GenericValidationThread, vrati domenu.

Returns:

getActualResult

public static FullValidationResult getActualResult()

Vrati aktualni ValidationResult - vezme aktualni vlakno a pokud se jedna o GenericValidationThread, vrati result.

Returns:
