Detailed Description

AipsIO storage manager for direct table arrays

Prerequisite

Etymology

StManColumnArrayAipsIO handles the access to a direct array in a table column using the AipsIO storage manager.

Synopsis

StManColumnArrayAipsIO holds the direct arrays in memory and writes them into the AipsIO file when the table gets closed. It fully supports addition and removal of rows. When a row is added to the table, the direct array gets allocated. This is possible, because the shape of direct arrays is known.

The class is derived from StManColumnAipsIO which is used to hold a pointer to the array.

Motivation

StManColumnArrayAipsIO handles the standard data types. The class is not templated, but a switch statement is used instead. Templates would cause too many instantiations.

Constructor & Destructor Documentation

◆ StManColumnArrayAipsIO() [1/2]

casacore::StManColumnArrayAipsIO::StManColumnArrayAipsIO ( StManAipsIO ,
int  dataType 
)

Create a column of the given data type.

◆ ~StManColumnArrayAipsIO()

virtual casacore::StManColumnArrayAipsIO::~StManColumnArrayAipsIO ( )
virtual

Member Function Documentation

◆ addRow()

virtual void casacore::StManColumnArrayAipsIO::addRow ( rownr_t  newNrrow,
rownr_t  oldNrrow 
)
virtual

Add (newNrrow-oldNrrow) rows to the column.

Allocate the data arrays in these rows if the shape is fixed.

Reimplemented from casacore::MSMColumn.

private

Forbid assignment.

◆ putArrayV()

virtual void casacore::StManColumnArrayAipsIO::putArrayV ( rownr_t  rownr,
const ArrayBase dataPtr

virtual

Put an array value into the given row.

The buffer pointed to by dataPtr has to have the correct length (which is guaranteed by the ArrayColumn put function).

Reimplemented from casacore::DataManagerColumn.

◆ putData()

virtual void casacore::StManColumnArrayAipsIO::putData ( void *  datap,
uInt  nrval,
AipsIO

◆ putFile()

virtual void casacore::StManColumnArrayAipsIO::putFile ( rownr_t  nrval,
AipsIO

virtual

Write the data into AipsIO.

This will call StManColumnAipsIO::putFile which will in its turn call putData in this class for each of its chunks of data.

Reimplemented from casacore::StManColumnAipsIO.

◆ remove()

virtual void casacore::StManColumnArrayAipsIO::remove ( rownr_t  rownr)
virtual

Remove the value in the given row.

Reimplemented from casacore::MSMColumn.

◆ setShapeColumn()

virtual void casacore::StManColumnArrayAipsIO::setShapeColumn ( const IPosition shape)
virtual

Set the (fixed) shape of the arrays in the entire column.

Reimplemented from casacore::DataManagerColumn.

◆ shape()

virtual IPosition casacore::StManColumnArrayAipsIO::shape ( rownr_t  rownr)
virtual

Get the shape of the array in the given row.

An zero-length IPosition is returned if there is no array.

Reimplemented from casacore::DataManagerColumn.
