Etymology

TSMCube represents a hypercube in the Tiled Storage Manager.

Synopsis

TSMCube defines a tiled hypercube. The data is stored in a TSMFile object and accessed using a BucketCache object. The hypercube can be extensible in its last dimension to support tables with a size which is not known in advance.
Normally hypercubes share the same TSMFile object, but extensible hypercubes have their own TSMFile object (to be extensible). If the hypercolumn has multiple data columns, their cells share the same tiles. Per tile data column A appears first, thereafter B, etc..
The data in the cache is held in external format and is converted when accessed. The alternative would be to hold it in the cache in local format and convert it when read/written from the file. It was felt that the latter approach would generate more needless conversions.

The possible id and coordinate values are stored in a Record object. They are written in the main hypercube AipsIO file.

TSMCube uses the maximum cache size set for a Tiled Storage manager. The description of class ROTiledStManAccessor contains a discussion about the effect of setting the maximum cache size.

Motivation

TSMCube encapsulates all operations on a hypercube.

◆ TSMCube() [1/3]

casacore::TSMCube::TSMCube ( TiledStMan stman,
TSMFile file,
const IPosition cubeShape,
const IPosition tileShape,
const Record values,
Int64  fileOffset,
Bool  useDerived = False 
)

Construct the hypercube using the given file with the given shape.

The record contains the id and possible coordinate values.
If the cubeshape is empty, the hypercube is still undefined and can be added later with setShape. That is only used by TiledCellStMan.
The fileOffset argument is meant for class TiledFileAccess.

AipsIO ios,
Bool  useDerived = False 
)

Reconstruct the hypercube by reading its data from the AipsIO stream.

It will link itself to the correct TSMFile. The TSMFile objects must have been reconstructed in advance.
