Constructor.

IDEA::PlasmaReactivePlannerImpl::~PlasmaReactivePlannerImpl (    )

Destructor.

Member Function Documentation

int IDEA::MessageObserver::activate (    )  [protected, virtual, inherited]

Activates the invoking message-observer. release all the messages we did not update

void IDEA::ReactivePlannerImpl::addRevocableAuthority (  int    authority )  [inherited]

Adds authority to the set of authorities of constraints which the invoking planner can revoke.

void IDEA::MessageObserver::deActivate (    )  [protected, virtual, inherited]

De-activates the invoking message-observer.

void IDEA::DefaultReactor::finalizeTokens (    )  [protected, inherited]

StatusType IDEA::PlasmaReactivePlannerImpl::free (  const PslToken *    pslTok )  [private, virtual]

Frees token pslTok. Reimplemented from IDEA::ReactivePlannerImpl.

bool IDEA::ReactivePlannerImpl::freeGoalTokens (    )  [protected, inherited]

Returns true if the invoking reactive planner should free goal tokens in case of an attempt recovery. Otherwise returns false.

AcceptorPolicy* IDEA::MessageObserver::getAcceptorPolicy (    )  const [inline, inherited]

Returns the current AcceptorPolicy of the invoking observer.

const AgentTimingService * IDEA::DefaultReactor::getAgentTimingService (    )  [inherited]

int IDEA::ReactivePlannerImpl::getAuthority (    )  [inherited]

Returns the authority of the planner of the invoking reactive planner.

const PslDatabase * IDEA::DefaultReactor::getDatabase (    )  [inherited]

const FreeStrategy & IDEA::ReactivePlannerImpl::getFreeStrategy (    )  [inherited]

Returns the strategy to use when we free a token.

void IDEA::PlasmaReactivePlannerImpl::getFutureTokens (  const PslTimeline *    timeline, PslTokenList &    tokensExecuting, PslTokenList &    tokensInTheFuture )  const [private, virtual]

Queries the tokens on timeline timeline and will store tokens which are scheduled completely in the futur in tokensInTheFuture and the tokens which is currently executing in tokensExecuting. Reimplemented from IDEA::ReactivePlannerImpl.

const std::string& IDEA::MessageObserver::getName (    )  const [inline, inherited]

Returns the name of the invoking observer.

int IDEA::MessageObserver::getNrOfPendingMessages (    )  [inline, inherited]

Returns the number of pending messages in the queue.

const Planner * IDEA::ReactivePlannerImpl::getPlanner (    )  [protected, inherited]

const IntSet & IDEA::ReactivePlannerImpl::getRevocableAuthorities (    )  [protected, inherited]

UpdatePolicy* IDEA::MessageObserver::getUpdatePolicy (    )  const [inline, inherited]

Returns the current UpdatePolicy of the invoking observer.

bool IDEA::MessageObserver::hasPendingMessages (    )  [inherited]

Returns true if the invoking observer has pending messages in the queue. Will take into account the logic of the UpdatePolicy, that is it will take the message at the top of the queue and check with the updatePolicy ( updateNextMessage( msg ) ) if it would be updated if we would invoke update. So there can be messages in the queue ( getNrOfPendingMessages() != 0 ) and this method returns false.

bool IDEA::MessageObserver::isActive (    )  const [inline, inherited]

Returns true if the invoking observer is active otherwise false.

bool IDEA::ReactivePlannerImpl::isRevocable (  int    authority )  const [inherited]

Returns true if the invoking planner can revoke constraints with authority authority.

Returns the old acceptor-policy if it was not deleted otherwise 0. The acceptor-policy is used to decide to accept messages when the invoking class is notified. Be aware the new policy will override the message-types to accept passed in the constructor of the invoking class.

void IDEA::DefaultReactor::setForgettingThePast (  bool    value )  [inherited]

void IDEA::ReactivePlannerImpl::setFreeGoalTokens (    )  [inherited]

Invoking this method will enable the freeing of goal-tokens in case of a recovery.
