Method Detail

offsetToIndex

public static Index offsetToIndex(int offset,
                                  int[] shape)

Given an offset (single index) and a set of dimensions compute the set of dimension indices that correspond to the offset.

indexToSlices

public static List<Slice> indexToSlices(Index indices)
                                 throws DapException

Convert ucar.ma2.Index to list of slices

Parameters:

indices - to convert

Returns:

list of corresponding slices

Throws:

DapException

slicesToIndex

public static D4Index slicesToIndex(List<Slice> slices)
                             throws DapException

If a set of slices refers to a single position, then return the corresponding Index. Otherwise, throw Exception.

Parameters:

slices -

Returns:

Index corresponding to slices

Throws:

DapException

toString

public String toString()

Overrides:

toString in class Index

index

public int index()

Compute the linear index from the current odometer indices. Not quite the same as super.currentElement(), which does not use shape[], but does use the super's "unexpected" notion of stride, although result may be same.

getCurrentCounter

public int getCurrentCounter(int i)

isScalar

public boolean isScalar()
