Member Function Documentation

void VAPoR::WaveletBlock3DRegionWriter::_GetDataRange ( float range[2] ) const

protectedvirtual

Implements VAPoR::WaveletBlockIOBase.

void VAPoR::WaveletBlock3DRegionWriter::_GetValidRegion	(	size_t	minreg[3],
		size_t	maxreg[3]
	)		const

protectedvirtual

Reimplemented from VAPoR::WaveletBlockIOBase.

int VAPoR::WaveletBlock3DRegionWriter::BlockWriteRegion	(	const float *	region,
		const size_t	bmin[3],
		const size_t	bmax[3],
		int	block = `1`
	)

Write a volume subregion to the currently opened multiresolution data volume.

This method is identical to the WriteRegion() method with the exception that the region boundaries are defined in block, not voxel, coordinates. Secondly, unless the 'block' parameter is set, the internal blocking of the data will be preserved. I.e. the data are assumed to already be blocked.

Parameters

[in]	bmin	Minimum region extents in block coordinates
[in]	bmax	Maximum region extents in block coordinates
[in]	region	The volume subregion to write
[in]	block	If true, block the data before writing/transforming

Return values

status Returns a non-negative value on success

See also: OpenVariableWrite(), Metadata::GetBlockSize(), MapVoxToBlk()

virtual int VAPoR::WaveletBlock3DRegionWriter::CloseVariable ( )

virtual

Close the data volume opened by the most recent call to OpenVariableWrite()

Return values

status Returns a non-negative value on success

See also: OpenVariableWrite()

Reimplemented from VAPoR::WaveletBlockIOBase.

virtual int VAPoR::WaveletBlock3DRegionWriter::OpenVariableRead	(	size_t	timestep,
		const char *	varname,
		int	reflevel = `0`,
		int	lod = `0`
	)

inlinevirtual

Open the named variable for reading

This method prepares the multiresolution data volume, indicated by a variable name and time step pair, for subsequent read operations by methods of this class. Furthermore, the number of the refinement level parameter, reflevel indicates the resolution of the volume in the multiresolution hierarchy. The valid range of values for reflevel is [0..max_refinement], where max_refinement is the maximum finement level of the data set: Metadata::GetNumTransforms(). volume when the volume was created. A value of zero indicates the coarsest resolution data, a value of max_refinement indicates the finest resolution data.

An error occurs, indicated by a negative return value, if the volume identified by the {varname, timestep, reflevel} tripple is not present on disk. Note the presence of a volume can be tested for with the VariableExists() method.

Parameters

[in]	timestep	Time step of the variable to read
[in]	varname	Name of the variable to read
[in]	reflevel	Refinement level of the variable. A value of -1 indicates the maximum refinment level defined for the VDC

Return values

status Returns a non-negative value on success

virtual int VAPoR::WaveletBlock3DRegionWriter::OpenVariableWrite	(	size_t	timestep,

	)

virtual

Open the named variable for writing

This method prepares the multiresolution data volume, indicated by a variable name and time step pair, for subsequent write operations by methods of this class. The number of refinement levels actually saved to the data collection are determined by reflevels. If reflevels is zero, the default, only the coarsest approximation is saved. If reflevels is one, the coarsest and first refinement level is saved, and so on. A value of -1 indicates the maximum refinment level permitted by the VDF

An error occurs, indicated by a negative return value, if the volume identified by the {varname, timestep, reflevel} can not be written .

Parameters

[in]	timestep	Time step of the variable to write
[in]	varname	Name of the variable to write
[in]	reflevel	Refinement level of the variable. A value of -1 indicates the maximum refinment level defined for the VDC

Return values

status Returns a non-negative value on success

int VAPoR::WaveletBlock3DRegionWriter::WriteRegion	(	const float *	region,
		const size_t	min[3],
		const size_t	max[3]
	)

virtual

Write a subregion to the currently opened multiresolution data volume. The min and max vectors identify the minium and maximum extents, in voxel coordinates, of the subregion of interest. The minimum valid value of 'min' is (0,0,0), the maximum valid value of max is (nx-1,ny-1,nz-1), where nx, ny, and nz are the voxel dimensions of the volume at the native resolution (finest resolution). The volume subregion to be written is pointed to by region.

Parameters

[in]	min	Minimum region extents in voxel coordinates
[in]	max	Maximum region extents in voxel coordinates
[in]	region	The volume subregion to write

Return values

status Returns a non-negative value on success
