Member Function Documentation

getEndpoint()

SimulationTimestampFileRead * wrench::SimulationTimestampFileRead::getEndpoint ( )

overridevirtual

Retrieve the matching endpoint, if any.

retrieves the corresponding SimulationTimestampFileRead object

Returns

a pointer to the start or end SimulationTimestampFileRead object

Reimplemented from wrench::SimulationTimestampPair.

getFile()

std::shared_ptr< DataFile > wrench::SimulationTimestampFileRead::getFile

(

)

retrieves the DataFile being read

Returns

a pointer to the DataFile associated with this reads

getService()

std::shared_ptr< StorageService > wrench::SimulationTimestampFileRead::getService

(

)

retrieves the storage service for file read

Returns

point to the service associated with this read

getSource()

std::shared_ptr< FileLocation > wrench::SimulationTimestampFileRead::getSource

(

)

retrieves the location from which the DataFile is being copied

Returns

the read's source location

getTask()

std::shared_ptr< WorkflowTask > wrench::SimulationTimestampFileRead::getTask

(

)

retrieves task associated w/ file read

Returns

a pointer to the WorkflowTask associated with this timestamp

Member Data Documentation

std::unordered_multimap< FileReadWrite, std::pair< SimulationTimestampFileRead *, std::shared_ptr< WorkflowTask > > > wrench::SimulationTimestampFileRead::pending_file_reads

staticprotected

the data structure that holds the ongoing file reads.

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