Detailed Description

a name server for pvm.

One of the important pre-conditions for the current implementation of distribution using pvm is that PsName are coherant across the simulation, because synchronisation messages are created and decoded using the order on PsNames. Moreover, the creation and interpretation is made robust and more or less efficient by encoding the ids associated to PsName rather than their string value

Member Function Documentation

virtual void PsPvmNameServer::created (  PsName::idType    id, PsName *    )  [virtual]

redefine to do nothing, because bookkeeping becomes to expensive due to unpacking Reimplemented from PsNameServerT< STL_ALLOC >.

virtual void PsPvmNameServer::deleted (  PsName::idType    id, PsName *    name )  [virtual]

redefine deleted to prevent destructions. In fact, deleted does nothing, because it becomes very expensive to do something due to unpacking. The name server serves as a cache... Reimplemented from PsNameServerT< STL_ALLOC >.

virtual long PsPvmNameServer::getIdentifierAsFrom (  const PsString &   , long *    nextId )  [virtual]

get the id corresponding to a string if the string is unknown to the name server, a new id will be added Reimplemented from PsNameServerT< STL_ALLOC >.

virtual const PsString& PsPvmNameServer::getStringAssociatedTo (  PsName::idType    id )  [protected, virtual]

get the string associated to an id this is the non-const version used when a request needs to be sent to the central server

virtual const PsString& PsPvmNameServer::getStringAssociatedTo (  PsName::idType    id )  const [virtual]

get the string associated to an id Reimplemented from PsNameServerT< STL_ALLOC >.

virtual bool PsPvmNameServer::includes (  const PsNameServer &    otherNameServer )  [virtual]

redefine includes to cancel check because a conversion has occured with respect to the original name server Reimplemented from PsNameServer.
