virtual int VAPoR::DataMgrRAMSES::_CloseVariable ( )

protectedvirtual

Close the currently opened variable.

Implements VAPoR::DataMgr.

virtual void VAPoR::DataMgrRAMSES::_GetBlockSize	(	size_t	bs[3],
		int	reflevel
	)		const

inlineprotectedvirtual

Return the internal blocking factor at a given refinement level

For multi-resolution data this method returns the dimensions of a data block at refinement level reflevel, where reflevel is in the range 0 to GetNumTransforms(). A value of -1 may be specified to indicate the maximum refinement level. In fact, any value outside the valid refinement level range will be treated as the maximum refinement level.

Parameters

[in]	reflevel	Refinement level

Implements VAPoR::DataMgr.

Definition at line 33 of file DataMgrRAMSES.h.

virtual const float* VAPoR::DataMgrRAMSES::_GetDataRange ( ) const

inlineprotectedvirtual

Return the data range for the currently open variable

The method returns the minimum and maximum data values, respectively, for the variable currently opened. If the variable is not opened, or if it is opened for writing, the results are undefined.

Returns: range A pointer to a two-element array containing the Min and Max data values, respectively. If the derived class' implementation of this method returns NULL, the DataMgr class will compute the min and max itself.

Reimplemented from VAPoR::DataMgr.

Definition at line 75 of file DataMgrRAMSES.h.

virtual void VAPoR::DataMgrRAMSES::_GetDim	(	size_t	dim[3],
		int	reflevel
	)		const

protectedvirtual

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.

Implements VAPoR::DataMgr.

virtual std::vector<double> VAPoR::DataMgrRAMSES::_GetExtents ( size_t ts ) const

inlineprotectedvirtual

Return the domain extents specified in user coordinates

Return the domain extents specified in user coordinates for the indicated time step. Variables in the data have spatial positions defined in a user coordinate system. These positions may vary with time. This method returns min and max bounds, in user coordinates, of all variables at a given time step.

Parameters

[in] ts A valid data set time step in the range from zero to GetNumTimeSteps() - 1. If ts is out of range, GetExtents() will return a reasonable default value.

Return values

extents A six-element array containing the min and max bounds of the data domain in user-defined coordinates. The first three elements specify the minimum X, Y, and Z bounds, respectively, the second three elements specify the maximum bounds.

Implements VAPoR::DataMgr.

virtual int VAPoR::DataMgrRAMSES::_GetNumTransforms ( ) const

inlineprotectedvirtual

Return number of transformations in hierarchy

For multi-resolution data this method returns the number of coarsened approximations present. If no approximations are available - if only the native data are present - the return value is 0.

		const char *	varname,
		int	reflevel,
		int	lod
	)

protectedvirtual

Open the named variable for reading

This method prepares the multi-resolution, multi-lod 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, and the lod parameter indicates the level of detail.

The valid range of values for reflevel is [0..max_refinement], where max_refinement is the maximum finement level of the data set: GetNumTransforms(). A value of zero indicates the coarsest resolution data, a value of max_refinement indicates the finest resolution data.

The valid range of values for lod is [0..max_lod], where max_lod is the maximum lod of the data set: GetCRatios().size() - 1. A value of zero indicates the highest compression ratio, a value of max_lod indicates the lowest compression ratio.

An error occurs, indicated by a negative return value, if the volume identified by the {varname, timestep, reflevel, lod} tupple 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
[in]	lod	Level of detail requested. A value of -1 indicates the lowest compression level available for the VDC

See also: GetVariables3D(), GetVariables2DXY(), GetNumTransforms()

Implements VAPoR::DataMgr.

virtual int VAPoR::DataMgrRAMSES::_VariableExists	(	size_t	ts,
		const char *	varname,
		int	reflevel = `0`,
		int	lod = `0`
	)		const

protectedvirtual

Returns true if indicated data volume is available

Returns true if the variable identified by the timestep, variable name, refinement level, and level-of-detail is present in the data set. Returns 0 if the variable is not present.

Parameters

[in]	ts	A valid time step between 0 and GetNumTimesteps()-1
[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.
[in]	lod	Compression level of detail requested. The coarsest approximation level is 0 (zero). A value of -1 indicates the finest refinement level contained in the VDC.
