Prerequisite

• StManArrayFile

Etymology

StIndArray stores indirect arrays on behalf of a storage manager.

Synopsis

StIndArray is a helper class for accessing indirect table arrays. It is the interface between a storage manager like StManAipsIO (in particular its indirect array column class

StManColumnIndArrayAipsIO) and the data storage class StManArrayFile which represents the file holding the shapes and data of the arrays. This file holds the data in canonical format.

StIndArray holds information about an array in the file.

1. Offset of the array in the file. This points to the array shape. This is stored by storage managers and serves as the mapping between row number and array.
2. Array data offset, i.e. the length of the shape in the file. Because the data is stored in canonical format, the length of the shape in the file is not directly known but has to be supplied this way.
3. The actual shape of the array

The storage manager creates an StIndArray object for each row. When an array is accessed for the first time, the array data offset and the shape will be filled in by StIndArray. In this way it serves as a cache for the array shape.

StIndArray implements all necessary functions to get/put an array or an array slice from/into file supplied by the given StManArrayFile object. The StManArrayFile object itself has to be created by the storage manager and given to the StIndArray functions.

Motivation

This helper class makes it possible to share equal functionality between various storage managers handling indirect arrays. At the moment it is used by the StManAipsIO, IncrementalStMan, and StandardStMan storage managers, but it is not limited to them. It can equally well be used by any other storage manager storing (indirect) arrays via an StManArrayFile object.

Example

Note that the following example is not really useful. StIndArray is an internal class and should not be used by a casual user. The example may however give a bit of insight.

Array<Float> array(...);
// Create an StManArrayFile object to hold the arrays.
StManArrayFile stmanFile ("some.name", ByteIO::New);
// Create a still empty StIndArray object for an array.
StIndArray arrayRef(0);
// Define the shape and allocate a Float array.
// Put the array data.
arrayRef.setShape (stmanFile, TpFloat, array.shape());
arrayRef.putArrayfloatV (stmanFile, &array);
// Get the file offset of the array (for later use).
Int64 offset = arrayRef.fileOffset();
// Create an StIndArray object to read the array back.
// Of course, the same object could have been used for that purpose,
// but this shows how to create one for an existing file.
StIndArray arrayRef2(offset);
arrayRef2.getShape (stmanFile);             // read shape
Array<float> array2(arrayRef2.shape());     // create with correct size
arrayRef2.getArrayfloatV (stmanFile, &array2);

To Do

• Reuse file storage when an array gets reshaped. This could be done if the array does not grow. It also requires a change in StManArrayFile.
• Be smarter when accessing slices by not accessing a vector at a time, but by determining and accessing the largest possible consecutive area.

StIndArray() [1/2]

casacore::StIndArray::StIndArray

Construct the object with the given file offset.

A zero file offset means that no array has been defined yet. That may be filled in later by setShape.

private

Get sliced data, i.e.

get a section of an array. This function is used by getSliceXXXV to have common functionality in one function. It calls the given getVec function for each chunk of data. In this way the bulk of type-independent code is concentrated in getSliceData resulting in small type-dependent functions.
