Base type for constraints applicable to a read/write/codec chunk grid.

This combines constraints on the chunk shape, chunk shape aspect ratio, and chunk shape target number of elements.

Constructors¶

explicit GridView();

Constructs a view of an unconstrained rank-0 grid.

explicit GridView(const GridView& other, bool hard_constraint);

explicit GridView(const Grid& grid, bool hard_constraint = true);

Constructs from an existing grid, optionally converting to hard constraints.

explicit GridView(ChunkShapeBase shape,
                  ChunkAspectRatioBase aspect_ratio,
                  ChunkElementsBase elements);

explicit GridView(ChunkShapeBase shape);

explicit GridView(ChunkAspectRatioBase aspect_ratio);

explicit GridView(ChunkElementsBase elements);

Constructs from individual constraints.

Methods¶

ChunkShapeBase shape() const;

Returns the shape constraint.

ChunkAspectRatioBase aspect_ratio() const;

Returns the aspect ratio constraint.

ChunkElementsBase elements() const;

Returns the target number of elements.
