Member Function Documentation

void Arc::DataMover::checks

(

bool

v

)

Set if to make check for existence of remote file (and probably other checks too) before initiating 'reading' and 'writing' operations.

Parameters:

v

true if allowed (default is true).

bool Arc::DataMover::checks

(

)

Check if check for existence of remote file is done before initiating 'reading' and 'writing' operations.

void Arc::DataMover::force_to_meta

(

bool

)

Set if file should be transferred and registered even if such LFN is already registered and source is not one of registered locations.

void Arc::DataMover::secure

(

bool

)

Set if high level of security (encryption) will be used during transfer if available.

void Arc::DataMover::set_default_max_inactivity_time

(

time_t

max_inactivity_time

)

[inline]

Set maximal allowed time for waiting for any data. For more information see description of DataSpeed class.

void Arc::DataMover::set_default_min_average_speed

(

unsigned long long int

min_average_speed

)

[inline]

Set minimal allowed average transfer speed (default is 0 averaged over whole time of transfer. For more information see description of DataSpeed class.

void Arc::DataMover::set_default_min_speed	(	unsigned long long int	min_speed,
		time_t	min_speed_time
	)			[inline]

Set minimal allowed transfer speed (default is 0) to 'min_speed'. If speed drops below for time longer than 'min_speed_time' error is raised. For more information see description of DataSpeed class.

DataStatus Arc::DataMover::Transfer	(	DataPoint &	source,
		DataPoint &	destination,
		FileCache &	cache,
		const URLMap &	map,
		unsigned long long int	min_speed,
		time_t	min_speed_time,
		unsigned long long int	min_average_speed,
		time_t	max_inactivity_time,
		callback	cb = NULL,
		void *	arg = NULL,
		const char *	prefix = NULL
	)

Initiates transfer from 'source' to 'destination'.

Parameters:

	min_speed	minimal allowed current speed.
	min_speed_time	time for which speed should be less than 'min_speed' before transfer fails.
	min_average_speed	minimal allowed average speed.
	max_inactivity_time	time for which should be no activity before transfer fails.

DataStatus Arc::DataMover::Transfer	(	DataPoint &	source,
		DataPoint &	destination,
		FileCache &	cache,
		const URLMap &	map,
		callback	cb = NULL,
		void *	arg = NULL,
		const char *	prefix = NULL
	)

Initiates transfer from 'source' to 'destination'.

Parameters:

	source	source URL.
	destination	destination URL.
	cache	controls caching of downloaded files (if destination url is "file://"). If caching is not needed default constructor FileCache() can be used.
	map	URL mapping/conversion table (for 'source' URL).
	cb	if not NULL, transfer is done in separate thread and 'cb' is called after transfer completes/fails.
	arg	passed to 'cb'.
	prefix	if 'verbose' is activated this information will be printed before each line representing current transfer status.

void Arc::DataMover::verbose

(

const std::string &

prefix

)

Activate printing information about transfer status.

Parameters:

prefix

use this string if 'prefix' in DataMover::Transfer is NULL.
