Parameters

[in]	reflevel	Refinement level requested. The coarsest refinement level is 0 (zero). A value of -1 indicates the finest refinement level contained in the VDC.
[out]	mins	The address of a pointer to float to which will be assigned the address of the internal min data array

virtual void VAPoR::WaveletBlockIOBase::GetDim	(	size_t	dim[3],
		int	reflevel = `0`
	)		const

virtual

Get the dimension of a volume

Returns the X,Y,Z coordinate dimensions of all data variables in grid (voxel) coordinates at the resolution level indicated by reflevel. Hence, all variables of a given type (3D or 2D) must have the same dimension. If reflevel is -1 (or the value returned by GetNumTransforms()) the native grid resolution is returned. In fact, any value outside the valid range is treated as the maximum refinement level

Parameters

[in]	reflevel	Refinement level of the variable
[out]	dim	A three element vector (ordered X, Y, Z) containing the voxel dimensions of the data at the specified resolution.

Get dimension of a volume in blocks

Performs same operation as GetDim() except returns dimensions in block coordinates instead of voxels.

Parameters

[in]	reflevel	Refinement level of the variable. A value of -1 indicates the maximum refinment level defined. In fact, any value outside the valid range is treated as the maximum refinement level
[out]	bdim	Transformed dimension in blocks.

virtual

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

		const char *	varname,

		int	lod = `-1`
	)

virtual

Open the named variable for writing

Prepare a vapor data file for the creation of a multiresolution data volume via subsequent write operations by other methods of this classes derived from this class. The data volume is identified by the specfied time step and variable name. The number of forward transforms applied to the volume is determined by the Metadata object used to initialize the 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, all the coarsest and first refinement level is saved, and so on. A value of -1 indicates the maximum refinment level permitted by the VDF

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.

Return values

status Returns a non-negative value on success

[in]	ts	A valid time step from the Metadata object used to initialize the class
[in]	varname	A valid variable name
[in]	reflevel	Refinement level requested. The coarsest refinement level is 0 (zero). A value of -1 indicates the finest refinement level contained in the VDC.
