Etymology

StManArrayFile is a class used by table storage managers to store indirect arrays in a file.

Synopsis

StManArrayFile is for use by the table storage manager, in particular to read/write indirectly stored arrays. Instead of holding the data in memory, they are written directly into a file. It also allows to access a part of an array, which is needed for the table system to access an array section. It does not use a cache of its own, but it is relying on the underlying system routines to cache and buffer adequately.

This class could in principle also be used for other array purposes, for example, to implement a paged array class for really huge arrays.

An StManArrayFile object is connected to one file. It is possible to hold multiple arrays in the file, each with its own shape. An array is stored as its shape followed by the actual data (all in little or big endian format). An array of strings is written as an array of offsets pointing to the actual strings. When a string gets a new value, the new value is written at the end of the file and the file space with the old value is lost.

Currently only the basic types are supported, but arbitrary types could also be supported by writing/reading an element in the normal way into the AipsIO buffer. It would only require that AipsIO would contain a function to get its buffers and to restart them.

Example

void writeArray (const Array<Bool>& array)
{
// Construct object and update file StArray.dat.
StManArrayFile arrayFile("StArray.dat, ByteIO::New);
// Reserve space for an array with the given shape and data type.
// This writes the shape at the end of the file and reserves
// space the hold the entire Bool array.
// It fills in the file offset where the shape is stored
// and returns the length of the shape in the file.
Int64 offset;
uInt shapeLength = arrayFile.putShape (array.shape(), offset, static_cast<Bool*>(0));
// Now put the actual array.
// This has to be put at the returned file offset plus the length
// of the shape in the file.
Bool deleteIt;
const Bool* dataPtr = array.getStorage (deleteIt);
arrayFile.put (offset+shapeLength, 0, array.nelements(), dataPtr);
array.freeStorage (dataPtr, deleteIt);
}

Motivation

The AipsIO class was not suitable for indirect table arrays, because it uses memory to hold the data. Furthermore it is not possible to access part of the data in AipsIO.

To Do

• implement long double
• support arbitrary types
• when rewriting a string value, use the current file space if it fits

Constructor & Destructor Documentation

StManArrayFile()

casacore::StManArrayFile::StManArrayFile	(	const String &	name,
		ByteIO::OpenOption	,
		uInt	version = 0,
		Bool	bigEndian = True,
		uInt	bufferSize = 0,
		MultiFileBase *	mfile = 0
	)

Construct the object and attach it to the give file.

The OpenOption determines how the file is opened (e.g. ByteIO::New for a new file). The buffersize is used to allocate a buffer of a proper size for the underlying filebuf object (see iostream package). A bufferSize 0 means using the default size (currently 65536).

~StManArrayFile()

casacore::StManArrayFile::~StManArrayFile

(

)

Close the possibly opened file.

Put the array shape and store its file offset into the offset argument.

Reserve file space for the associated array. The length of the shape part in the file is returned. The file offset plus the shape length is the starting offset of the actual array data (which can be used by get and put). Space is reserved to store the reference count.
