Member Function Documentation

doSynchronousFileCopy()

void wrench::DataMovementManager::doSynchronousFileCopy	(	std::shared_ptr< DataFile >	file,
		std::shared_ptr< FileLocation >	src,
		std::shared_ptr< FileLocation >	dst,
		std::shared_ptr< FileRegistryService >	file_registry_service = nullptr
	)

Ask the data manager to perform a synchronous file copy.

Parameters

file	the file to copy
src	the source location
dst	the destination location
file_registry_service	a file registry service to update once the file copy has (successfully) completed (none if nullptr)

Exceptions

std::invalid_argument
ExecutionException

initiateAsynchronousFileCopy()

void wrench::DataMovementManager::initiateAsynchronousFileCopy	(	std::shared_ptr< DataFile >	file,
		std::shared_ptr< FileLocation >	src,
		std::shared_ptr< FileLocation >	dst,
		std::shared_ptr< FileRegistryService >	file_registry_service = nullptr
	)

Ask the data manager to initiate an asynchronous file copy.

Parameters

file	the file to copy
src	the source location
dst	the destination location
file_registry_service	a file registry service to update once the file copy has (successfully) completed (none if nullptr)

Exceptions

std::invalid_argument
ExecutionException

stop()

void wrench::DataMovementManager::stop ( )

overridevirtual

Stop the manager.

Exceptions

ExecutionException
std::runtime_error

Reimplemented from wrench::Service.
