Function documentation

static void eckit::HyperCube::combine(Remapping&, const Remapping&)

Combines two 'remapping' vectors.

Method is inlined for speed.

Ordinal eckit::HyperCube::index(const Coordinates&) const

Translate coordinates into an index to a 1 dimension array.

Method is inlined for speed.

Ordinal eckit::HyperCube::count() const

Method is inlined for speed.

Returns the number of elemets

HyperCube eckit::HyperCube::addToDimension(Ordinal which, Ordinal where, Ordinal count, Remapping&) const

Returns the 'remapping' std::vector needing to add 'count' labels for the dimension 'which' at position 'where'
