Member Function Documentation

int VAPoR::ImpExp::Export	(	const string &	path,
		size_t	ts,
		const string &	varname,
		const size_t	min[3],
		const size_t	max[3],
		const size_t	timeseg[2]
	)

Export a volume subregion description for use by another application

This method exports data set state information to facilitate sharing with another application. In particular, the path name of the VDF file, a volume time step, a named volume variable, and volumetric region of interest are exported. The exported information may be retreive via the Import() method

Note

The region bounds are specified relative to the finest resolution volume

Presently the medium of exchange is an XML file, the path to which is internally hardwired and based on the user's uid. Thus it is not possible for applications running under different uid's to share data. Furthermore, there exists only one XML file per uid on a system. This will undoubtedly change in the future.

Parameters

[in]	path	Path to the metadata file
[in]	ts	Time step of exported volume
[in]	varname	Variable name of exported volume
[in]	min	Minimum region extents in voxel coordinates relative to the finest resolution
[in]	max	Maximum region extents in voxel coordinates relative to the finest resolution
[in]	timeseg	Time segment range

Return values

status

Returns a non-negative integer on success

int VAPoR::ImpExp::Import	(	string *	path,

		string *	varname,
		size_t	min[3],
		size_t	max[3],
		size_t	timeseg[2]
	)

Import a volume subregion description for use by another application

This method imports data set state information to facilitate sharing with another application. In particular, the path name of the VDF file, a volume time step, a named volume variable, and volumetric region of interest are imported. The imported information is assumed to have been generated via the the most recent call to the Export() method.

Parameters

[out]	path	Path to the metadata file
[out]	ts	Time step of exported volume
[out]	varname	Variable name of exported volume
[out]	min	Minimum region extents in voxel coordinates relative to the finest resolution
[out]	max	Maximum region extents in voxel coordinates relative to the finest resolution
[out]	timeseg	Time segment range

Return values

status

Returns a non-negative integer on success
