public abstract class AbstractAutoSwitchedMixCascadeContainer
extends AbstractMixCascadeContainer

This class returns a new random cascade from all currently available cascades every time getNextCascade() is called. If all available cascades have been returned once, this class starts again by choosing the random cascades from all available ones.

Constructor Detail

AbstractAutoSwitchedMixCascadeContainer

public AbstractAutoSwitchedMixCascadeContainer(boolean a_bSkipInitialCascade,
                                               MixCascade a_initialCascade)

Method Detail

getInitialCascade

public final MixCascade getInitialCascade()

getNextRandomCascade

public final MixCascade getNextRandomCascade()

Explicitly chooses the next cascade at random. If auto-reconnect is active, this method is equal to getNextCascade().

Returns:

the next cascade at random

getNextCascade

public final MixCascade getNextCascade()

Description copied from class: AbstractMixCascadeContainer

Must return a MixCascade and never null. The returned MixCascade may change with every call of this method.

Specified by:

getNextCascade in class AbstractMixCascadeContainer

Returns:

a MixCascade and never null

getNextCascade

private final MixCascade getNextCascade(boolean a_bForceNextRandom)

isServiceAutoSwitched

public abstract boolean isServiceAutoSwitched()

Specified by:

isServiceAutoSwitched in interface IServiceContainer

Specified by:

isServiceAutoSwitched in class AbstractMixCascadeContainer

isReconnectedAutomatically

public abstract boolean isReconnectedAutomatically()

Specified by:

isReconnectedAutomatically in interface IServiceContainer

Specified by:

isReconnectedAutomatically in class AbstractMixCascadeContainer

isPaidServiceAllowed

public abstract boolean isPaidServiceAllowed()

isSuitableCascade

private final boolean isSuitableCascade(MixCascade a_cascade)

getCurrentCascade

public final MixCascade getCurrentCascade()

Description copied from class: AbstractMixCascadeContainer

Returns the last return value of getNextCascade().

Specified by:

getCurrentCascade in class AbstractMixCascadeContainer

Returns:

the last return value of getNextCascade() (may be null if no call has been done yet)

setCurrentCascade

public final boolean setCurrentCascade(MixCascade a_cascade)

keepCurrentService

public final void keepCurrentService(boolean a_bKeepCurrentCascade)

Description copied from class: AbstractMixCascadeContainer

Optional method that should allow to return the last MixCascade (Service) that was returned by getNextService() also the next time this method is called.

Specified by:

keepCurrentService in interface IServiceContainer

Specified by:

keepCurrentService in class AbstractMixCascadeContainer

Parameters:

a_bKeepCurrentCascade - allows or dissallows to keep the current cascade for the next call

checkTrust

public final void checkTrust(MixCascade a_cascade)
                      throws TrustException,
                             java.security.SignatureException

Specified by:

checkTrust in interface ITrustModel

Overrides:

checkTrust in class BasicTrustModel

Throws:

TrustException
