References VAPoR::DCReaderWRF::CloseVariable().

virtual void VAPoR::DataMgrWRF::_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]reflevelRefinement level
bs]dim Transformed dimension.
Return values
bsA three element vector containing the voxel dimension of a data block

Definition at line 43 of file DataMgrWRF.h.

References VAPoR::DCReaderWRF::GetGridDim().

virtual const float* VAPoR::DataMgrWRF::_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 118 of file DataMgrWRF.h.

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

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]reflevelRefinement level of the variable
[out]dimA three element vector (ordered X, Y, Z) containing the voxel dimensions of the data at the specified resolution.

virtual vector<double> VAPoR::DataMgrWRF::_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]tsA 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
extentsA 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.

float &  value 
) const
inlineprotectedvirtual

Return the value of the missing data value

This method returns the value of the missing data value for the currently opened variable. If no missing data are present the method returns false

Parameters

virtual double VAPoR::DataMgrWRF::_GetTSUserTime ( size_t  ts) const
inlineprotectedvirtual

Return the time for a time step

This method returns the time, in user-defined coordinates, associated with the time step, ts. Variables such as velocity field components that are expressed in distance per units of time are expected to use the same time coordinates as the values returned by this mehtod.

Parameters
[in]tsA valid data set time step in the range from zero to GetNumTimeSteps() - 1.

This method returns the user time, associated with the time step, ts, as a formatted string. The returned time stamp is intended to be used for annotation purposes

Parameters
[in]tsA valid data set time step in the range from zero to GetNumTimeSteps() - 1.
[out]sA formated time string. If ts is outside the valid range zero the empty string is returned.

size_t  max[3],
int  reflevel

[out]maxA pointer to the maximum bounds of the subvolume
[in]reflevelRefinement level of the variable. A value of -1 indicates the maximum refinment level defined for the VDC

virtual int VAPoR::DataMgrWRF::_OpenVariableRead ( size_t  timestep,
const char *  varname,
int  reflevel,
int  lod 
)
inlineprotectedvirtual

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]timestepTime step of the variable to read
[in]varnameName of the variable to read
[in]reflevelRefinement level of the variable. A value of -1 indicates the maximum refinment level defined for the VDC
[in]lodLevel of detail requested. A value of -1 indicates the lowest compression level available for the VDC
