Etymology

SSMDirColumn represents a Direct Array Column in the Standard Storage Manager.

Synopsis

SSMDirColumn handles the access to a column containing direct arrays of the various data types.
It is derived from SSMColumn and uses most of its functions. The only thing done differently in this class is that it maintains no cache. Furthermore fixed length strings are not handled specially. All string arrays are stored in the special string buckets.

Constructor & Destructor Documentation

◆ SSMDirColumn() [1/2]

casacore::SSMDirColumn::SSMDirColumn ( SSMBase aParent,
int  aDataType,
uInt  aColNr 
)

Create a SSMDirColumn object with the given parent.

It initializes the various variables. It keeps the pointer to its parent (but does not own it).

◆ ~SSMDirColumn()

virtual casacore::SSMDirColumn::~SSMDirColumn ( )
virtual

◆ SSMDirColumn() [2/2]

casacore::SSMDirColumn::SSMDirColumn ( const SSMDirColumn )
private

Forbid copy constructor.

Member Function Documentation

◆ deleteRow()

virtual void casacore::SSMDirColumn::deleteRow ( rownr_t  aRowNr)
virtual

Remove the given row from the data bucket and possibly string bucket.

Reimplemented from casacore::SSMColumn.

◆ getArrayV()

virtual void casacore::SSMDirColumn::getArrayV ( rownr_t  rownr,
ArrayBase dataPtr 
)
virtual

Get an array value in the given row.

Reimplemented from casacore::DataManagerColumn.

Reimplemented in casacore::SSMIndStringColumn.

◆ getValue()

void casacore::SSMDirColumn::getValue ( rownr_t  aRowNr,
void *  data 
)
protected

Read the array data for the given row into the data buffer.

◆ operator=()

SSMDirColumn& casacore::SSMDirColumn::operator= ( const SSMDirColumn )
private

Forbid assignment.

◆ putArrayV()

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

Put an array value in the given row.

Reimplemented from casacore::DataManagerColumn.

Reimplemented in casacore::SSMIndStringColumn.

◆ setMaxLength()

virtual void casacore::SSMDirColumn::setMaxLength ( uInt  maxLength)
virtual

An array of 'fixed length' strings is not handled specially, thus this function is ignored.

It is needed to override the bahviour of the base class.

Reimplemented from casacore::SSMColumn.
