Member Function Documentation

getBytes()

double wrench::SimulationTimestampDiskRead::getBytes

(

)

retrieves the amount of bytes being read

Returns

number of bytes as double

getCounter()

int wrench::SimulationTimestampDiskRead::getCounter

(

)

To get counter of disk operation.

Returns

int of counter

getEndpoint()

SimulationTimestampDiskRead * wrench::SimulationTimestampDiskRead::getEndpoint ( )

overridevirtual

Retrieve the matching endpoint, if any.

retrieves the corresponding SimulationTimestampDiskRead object

Returns

a pointer to the start or end SimulationTimestampDiskRead object

Reimplemented from wrench::SimulationTimestampPair.

getHostname()

std::string wrench::SimulationTimestampDiskRead::getHostname

(

)

retrieves the hostname where read occurs

Returns

string of hostname

getMount()

std::string wrench::SimulationTimestampDiskRead::getMount

(

)

retrieves mount point of read

Returns

string of mount point

Member Data Documentation

pending_disk_reads

std::unordered_multimap< DiskAccess, SimulationTimestampDiskRead * > wrench::SimulationTimestampDiskRead::pending_disk_reads

staticprotected

the data structure that holds the ongoing disk reads.

A static unordered multimap of SimulationTimestampDiskReadStart objects that have yet to be matched with Failure, Terminated or Completion timestamps.
