public SampleModel getSampleModel()

getSpatialDomain

public VariableAdapter.UnidataSpatialDomain getSpatialDomain()

Overrides:

getSpatialDomain in class CoverageSourceDescriptor

getTemporalDomain

public VariableAdapter.UnidataTemporalDomain getTemporalDomain()

Overrides:

getTemporalDomain in class CoverageSourceDescriptor

getVerticalDomain

public VariableAdapter.UnidataVerticalDomain getVerticalDomain()

Overrides:

getVerticalDomain in class CoverageSourceDescriptor

getWidth

public int getWidth()

Returns:

getHeight

public int getHeight()

Returns:

getNDimensionIndex

public int getNDimensionIndex(int n)

Utility method to retrieve the index of a specific dimension index, for constructing the range

Parameters:

n - the dimension to retrieve the index for (0=Z, 1=T, 2+=Additional)

Returns:

the index

getNIndex

public int getNIndex(int n,
                     int imageIndex)

Utility method to retrieve the n-index of a Variable coverageDescriptor stored on NetCDFImageReader NetCDF Flat Reader HashMap indexMap.

Parameters:

n - int the dimension

imageIndex - int the image index

Returns:

n-index int -1 if not present

splitIndex

public int[] splitIndex(int imageIndex)

Utility method to split the index of a Variable coverageDescriptor stored on NetCDFImageReader NetCDF Flat Reader HashMap indexMap into dimensions.

Parameters:

imageIndex - int the index

Returns:

splitted index

mapIndex

public Map<String,Integer> mapIndex(int[] splittedIndex)

getNumberOfSlices

public int getNumberOfSlices()

Returns:

the numberOfSlices

getShape

public int[] getShape()

Returns:

the shape

getFeatures

public int getFeatures(int startIndex,
                       int limit,
                       ListFeatureCollection collection)

Return features for that variable adapter, starting from slices with index = "startIndex", and up to "limit" elements. This allows for paging. Put the created features inside the provided collection

Parameters:

startIndex - the first slice to be returned

limit - the max number of features to be created

collection - the feature collection where features need to be stored

clearCache

public static void clearCache()

Clear the parsed unit cache
