Detailed Description

Interface for a step in the serialization of entity families.

This interface is used by IItemFamilyExchanger to serialize and deserialize information. Serialization is done by message exchange and there is one message per rank with which we communicate.

The call pseudo-code is as follows:

IItemFamilyExchanger* exchanger = ...;
IItemFamilySerializeStep* step = ...;
exchanger->computeExchangeInfos();
step->initialize();
// Some exchanger action
...
step->notifyAction(AC_BeginPrepareSend);
// Set serialize mode to ISerializer::ModeReserve
for( Integer i=0; i<nb_message; ++i )
  step->serialize(i);
// Set serialize mode to ISerializer::ModePut
for( Integer i=0; i<nb_message; ++i )
  step->serialize(i);
step->notifyAction(AC_EndPrepareSend);
exchanger->processExchange();
step->notifyAction(AC_BeginReceive);
// Set serialize mode to ISerializer::ModeGet
for( Integer i=0; i<nb_message; ++i )
  step->serialize(i);
step->notifyAction(AC_EndReceive);
step->finalize();

The serialize() method is called for each rank we communicate with.

The step is called during the serialization phase specified by phase() as specified in the IItemFamilyExchanger documentation.

For the specified phase, the call order is as follows:

IItemFamilySerializeStep* step = ...;
ISerializer* sbuf = ...;
sbuf->setMode(ISerializer::ModeReserve)
step->beginSerialize(sbuf->mode())

Member Function Documentation

family()

virtual IItemFamily * Arcane::IItemFamilySerializeStep::family ( ) const

pure virtual

Associated family.

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.

finalize()

virtual void Arcane::IItemFamilySerializeStep::finalize ( )

pure virtual

Performs end-of-exchange processing.

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.

initialize()

virtual void Arcane::IItemFamilySerializeStep::initialize ( )

pure virtual

Initializes the instance before the start of exchanges.

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.

notifyAction()

virtual void Arcane::IItemFamilySerializeStep::notifyAction ( const NotifyActionArgs & args )

pure virtual

Notifies the instance that we are entering a certain phase of the exchange.

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.

phase()

virtual ePhase Arcane::IItemFamilySerializeStep::phase ( ) const

pure virtual

Serialization phase where this instance is involved.

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.

serialize()

virtual void Arcane::IItemFamilySerializeStep::serialize ( const ItemFamilySerializeArgs & args )

pure virtual

Serializes into/from buf.

args.rank() contains the rank of the subdomain with which we communicate. args.messageIndex() is the message number index and args.nbMessageIndex() is the number of messages that will be sent.

During serialization, these are the local indices of the entities sent to rank rank(). During deserialization, these are the local indices received by rank rank().

Implemented in Arcane::Materials::MeshMaterialExchangeMng::ExchangeCellStep.
