void VAPoR::DCReaderWRF::GetBlockSize	(	size_t	bs[3],
		int	reflevel
	)		const

inlinevirtual

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
	bs]	dim Transformed dimension.

Return values

bs	A three element vector containing the voxel dimension of a data block

virtual std::vector<string> VAPoR::DCReaderWRF::GetCoordinateVariables ( ) const

inlinevirtual

Return the names of the coordinate variables.

This method returns a three-element vector naming the X, Y, and Z coordinate variables, respectively. The special name "NONE" indicates that a coordinate variable name does not exist for a particular dimension.

Note: The existence of a coordinate variable name does not imply the existence of the coordinate variable itself.

Return values

vector is three-element vector of coordinate variable names.

virtual std::vector<double> VAPoR::DCReaderWRF::GetExtents ( size_t ts = 0 ) const

virtual

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.

Return the Longitude and Latitude extents of the grid

This method returns the longitude extents (west-most and east-most) points, and the latitude extents (south-most and north-most) in degrees.

virtual

Open the named variable for reading

This method prepares a data volume (slice), indicated by a variable name and time step pair, for subsequent read operations by methods of this class. The number of the refinement levels 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 refinement level of the data set: Metadata::GetNumTransforms(). A value of zero indicates the coarsest resolution data, a value of max_refinement (or -1) indicates the finest resolution data. The level-of-detail parameter, lod, selects the approximation level. Valid values for lod are integers in the range 0..GetCRatios().size()-1, or the value -1 may be used to select the best approximation available: GetCRatios().size()-1.

An error occurs, indicated by a negative return value, if the volume identified by the {varname, timestep, reflevel, lod} tupple is not available. Note the availability of a volume can be tested 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	Approximation level of the variable. A value of -1 indicates the maximum approximation level defined for the VDC

Return values

status Returns a non-negative value on success

virtual int VAPoR::DCReaderWRF::ReadSlice ( float * slice )

virtual

Read the next volume slice from the currently opened file Read in and return a slice (2D array) of voxels from the currently opened data volume at the current refinement level. Subsequent calls will read successive slices until the entire volume has been read. It is the caller's responsibility to ensure that the array pointed to by slice contains enough space to accomodate an NX by NY dimensioned slice, where NX is the dimesion of the volume along the X axis, specified in voxels, and NY is the Y axis dimension, as returned by GetDim().

Note: ReadSlice returns 0 if the entire volume has been read.

Parameters

[out] slice The requested volume slice

Return values

status Returns a non-negative value on success

Return true if the named variable is available

This method returns true if the variable named by varname is available in the data collection at the time step given by ts, and the specified level-of-detail and resolution.. A variable may be contained in a data set, but not exist for all time steps, levels-of-detail, etc..

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	Approximation level of the variable. A value of -1 indicates the maximum approximation level defined for the VDC

Return values
