◆ SnowpackInterfaceWorker()

SnowpackInterfaceWorker::SnowpackInterfaceWorker	(	const mio::Config &	io_cfg,
		const mio::DEMObject &	dem_in,
		const mio::Grid2DObject &	landuse_in,
		const std::vector< std::pair< size_t, size_t > > &	pts_in,
		const std::vector< SnowStation * > &	snow_stations,
		const std::vector< std::pair< size_t, size_t > > &	snow_stations_coord,
		const std::vector< std::string > &	grids_not_computed_in_worker
	)

Constructs and initialise Snowpack Interface Worker. Create one worker and init values for slice which the worker need to simulate it slice.

Parameters

[in]	io_cfg	configuration to pass to Snowpack
[in]	dem_in	gives the demographic Data. Also tetermines size and position of the slice
[in]	landuse_in	gives the landuse Data. Also tetermines size and position of the landuse for slice
[in]	pts_in	gives the spezial points. For this points more output is done then for the others. Calcualtion is the same.
[in]	snow_stations	gives a vector of pointers to the SnowStation objects relevant for this thread
[in]	snow_stations_coord	provide the (ii,jj) coordinates of each snow station. This is necessary because the slices might be irregular
[in]	grids_not_computed_in_worker	vector of grids that are required but will be computed outside the workers
