Constructor & Destructor Documentation

Infiniband::Port::Port (  const Node *  node, int  portnum )

Default constructor. Parameters: [in]  node  A pointer to the Node object where this Port object resides [in]  portnum  The port number of this Port object for the Node object Exceptions: FountainException  if the smp_query() fails to get this port's information or if the port's physical state is not active

Infiniband::Port::Port (  const Port &  rhs  )

Copy constructor. Parameters: [in]  rhs  The Port object to copy from

---

Member Function Documentation

void Infiniband::Port::addInfo (  BambooLib::XMLElement *  portElement  )

Append this ports's usage information to the portElement. Parameters: [in]  portElement  A pointer to the XMLElement to add the information

bool Infiniband::Port::checkStuckPortCounters (   )  [private]

Checks for port counters that have maxed out their values. Return values: bool  True if the port counters will be reset during the next query Postcondition: resetMask will be set with the appropriate bitmask if the result is true

Infiniband::Port & Infiniband::Port::operator= (  const Port &  rhs  )

Assignment operator. Parameters: [in]  rhs  The Port object to copy from Return values: Port  Reference to a Port object

void Infiniband::Port::query (  uint32_t  lid  )

Update this ports port counters. Parameters: [in]  lid  The lid of the node to query

void Infiniband::Port::setGuid (  uint64_t  guid  )  [inline]

Sets the remote node GUID for this port. Parameters: [in]  guid  The GUID to use
