NRAOCASA: casa::DataManagerColumn Class Reference

DataManagerColumn is the abstract base class to handle a column in a data manager. Each data manager class must have one or more associated classes derived from DataManagerColumn to handle the columns. For example, storage manager StManAipsIO has columns classes StManColumnAipsIO, StManColumnArrayAipsIO and StManColumnIndArrayAipsIO to handle scalars, direct arrays and indirect arrays, resp.\. However, using multiple inheritance it is possible that the derived DataManager and DataManagerColumn classes are the same. This is used in class ScaledArrayEngine<S,T> which represents both the data manager and its column class. It can do that, because the virtual column engine ScaledArrayEngine can handle only one column.

In the synopsis of class DataManager it is described how the (derived) DataManagerColumn objects gets created and deleted.

DataManagerColumn defines various virtual functions to get or put (slices) of data in a column. These functions are called by the table column classes ScalarColumnData and ArrayColumnData. It does not define functions create, open, flush and prepare like those defined in DataManager. It is left to the derived classes to define those as needed and to interact properly with their data manager object.

Motivation

An abstract base class is needed to support multiple data managers in the table system

Constructor & Destructor Documentation

casa::DataManagerColumn::DataManagerColumn ( ) [inline]

Create a column.

Definition at line 537 of file DataManager.h.

virtual casa::DataManagerColumn::~DataManagerColumn ( ) [virtual]

Frees up the storage.

casa::DataManagerColumn::DataManagerColumn ( const DataManagerColumn & ) [private]

The copy constructor cannot be used for this base class.

The private declaration of this constructor makes it unusable.

Member Function Documentation

void casa::DataManagerColumn::setIsFixedShape ( Bool isFixedShape ) [inline]

Set the isFixedShape flag.

Definition at line 544 of file DataManager.h.

References isFixedShape_p.

Bool casa::DataManagerColumn::isFixedShape ( ) const [inline]

Is this a fixed shape column?

Definition at line 548 of file DataManager.h.

References isFixedShape_p.

virtual int casa::DataManagerColumn::dataType ( ) const [pure virtual]

Get the data type of the column as defined in DataType.h.

virtual String casa::DataManagerColumn::dataTypeId ( ) const [virtual]

Get the data type id of the column for dataType==TpOther.

The default implementation returns an emptry string. This function is required for virtual column engines handling non-standard data types. It is used to check the data type.

virtual Bool casa::DataManagerColumn::isWritable ( ) const [virtual]

Test if data can be put into this column.

This does not test if the data file is writable, only if it is in principle allowed to store data into the column. (It may not be allowed for virtual columns). The default is True.

virtual void casa::DataManagerColumn::setMaxLength ( uInt maxLength ) [virtual]

Set the maximum length of the value (can be used for strings).

By default the maximum length is ignored.

void casa::DataManagerColumn::setFixedShapeColumn ( const IPosition & shape ) [inline]

Set the shape of all (fixed-shaped) arrays in the column.

Effectively it is the same as setShapeColumn, but it also sets the isFixedShape_p flag.

Definition at line 574 of file DataManager.h.

References isFixedShape_p, setShapeColumn(), shape(), and casa::True.

virtual void casa::DataManagerColumn::setShape	(	uInt	rownr,
		const IPosition &	shape
	)			`[virtual]`

Set the shape of an (variable-shaped) array in the given row.

By default it throws a "not possible" exception.

virtual void casa::DataManagerColumn::setShapeTiled	(	uInt	rownr,
		const IPosition &	shape,
		const IPosition &	tileShape
	)			`[virtual]`

Set the shape and tile shape of an (variable-shaped) array in the given row.

By default it ignores the tile shape (thus only sets the shape).

virtual Bool casa::DataManagerColumn::isShapeDefined ( uInt rownr ) [virtual]

Is the value shape defined in the given row? By default it returns True.

virtual uInt casa::DataManagerColumn::ndim ( uInt rownr ) [virtual]

Get the dimensionality of the item in the given row.

By default it returns shape(rownr).nelements().

virtual IPosition casa::DataManagerColumn::shape ( uInt rownr ) [virtual]

Get the shape of the item in the given row.

By default it returns a zero-length IPosition (for a scalar value).

virtual Bool casa::DataManagerColumn::canChangeShape ( ) const [virtual]

Can the data manager handle chaging the shape of an existing array? Default is no.

virtual Bool casa::DataManagerColumn::canAccessScalarColumn ( Bool & reask ) const [virtual]

Can the column data manager handle access to a scalar column? If not, the caller should access the column by looping through all cells in the column.

Default is no.
The returned reask switch determines if the information is permanent. False indicates it is permanent; True indicates it will be reasked for the next get/putColumn. By default reask is set to False.

virtual Bool casa::DataManagerColumn::canAccessScalarColumnCells ( Bool & reask ) const [virtual]

Can the column data manager handle access to a clooection of cells in a scalar column? If not, the caller should access the column cells by looping through the cells in the column.

void casa::DataManagerColumn::get	(	uInt	rownr,
		Bool *	dataPtr
	)			`[inline]`

Get the scalar value in the given row.

These functions are non-virtual and are converted to their virtual getV equivalent to achieve that a derived templated class (like VirtualScalarColumn) does not have to declare and implement all these functions. The compiler complains about hiding virtual functions if you do not declare all virtual functions with the same name in a derived class.
