Etymology

ArrayColumn<T> gives read and write access to an column in a table containing an array with data type T.

Synopsis

ArrayColumnBase is the base class of the templated class ArrayColumn which allows readonly access to a column containing arrays with an arbitrary data type. It can handle direct as well as indirect arrays.

All get and put functions are implemented in this base class as non-templated functions. Type-specific operations are done by means of virtual functions in the Array classes.

Example

See module Tables.

Constructor & Destructor Documentation

casacore::ArrayColumnBase::ArrayColumnBase ( )

The default constructor creates a null object, i.e.

it does not reference a table column.

casacore::ArrayColumnBase::ArrayColumnBase	(	const Table &	,
		const String &	columnName
	)

Construct for the given column in the given table.

casacore::ArrayColumnBase::ArrayColumnBase ( const TableColumn & column )

Construct from the given table column.

This constructor is useful if first a table column was constructed, its type is determined and thereafter used to construct the correct column object.

casacore::ArrayColumnBase::ArrayColumnBase ( const ArrayColumnBase & )

Copy constructor (reference semantics).

casacore::ArrayColumnBase::~ArrayColumnBase ( )

Member Function Documentation

void casacore::ArrayColumnBase::acbFillColumn ( const ArrayBase & value )

Put the same value in all cells of the column.

void casacore::ArrayColumnBase::acbGet	(	rownr_t	rownr,
		ArrayBase &	array,
		Bool	resize
	)		const

Get the array value in a particular cell (i.e.

table row). The row numbers count from 0 until #rows-1.

void casacore::ArrayColumnBase::acbGetColumn	(	ArrayBase &	array,
		Bool	resize
	)		const

Get the array of all values in a column.

If the column contains n-dim arrays, the resulting array is (n+1)-dim with the last dimension representing the number of rows. The arrays in the column must have the same shape in all cells.

Referenced by casacore::GetColumnSlices::apply().

void casacore::ArrayColumnBase::acbGetColumn	(	const Slicer &	arraySection,
		ArrayBase &	array,
		Bool	resize
	)		const

Get regular slices from all arrays in the column.

If the column contains n-dim arrays, the resulting array is (n+1)-dim. with the last dimension representing the number of rows and the other dimensions representing the shape of the slice. The arrays in the column must have the same shape in all cells.

void casacore::ArrayColumnBase::acbGetColumn	(	const Vector< Vector< Slice > > &	arraySection,
		ArrayBase &	array,
		Bool	resize
	)		const

Get irregular slices from all arrays in the column as given by the vectors of Slice objects.

The outer vector represents the array axes. A missing or empty axis means the entire axis. The inner vector represents the slices to take for each axis. For example, to get slices from 2-dim arrays:

Vector<Vector<Slice> > slices(2);      // 2-dim
slices[1].resize (3);                  // 3 slices in 2nd dim
slices[1][0] = Slice(100,20);
slices[1][1] = Slice(200,18);
slices[1][2] = Slice(538,30,2);
// Get data. Vector of first axis is empty, thus entire axis is read.
Array<Complex> data = dataCol.getColumn (slices);

If the column contains n-dim arrays, the resulting array is (n+1)-dim. with the last dimension representing the number of rows and the other dimensions representing the shape of the slice. The arrays in the column must have the same shape in all cells.

	)		const

Get various slices from the given rows.

void casacore::ArrayColumnBase::acbGetColumnRange	(	const Slicer &	rowRange,
		ArrayBase &	arr,
		Bool	resize
	)		const

Get the array of some values in a column.

The Slicer object can be used to specify start, end (or length), and stride of the rows to get. If the column contains n-dim arrays, the resulting array is (n+1)-dim with the last dimension representing the number of rows in the slicer. The arrays in the column must have the same shape in all those cells.

void casacore::ArrayColumnBase::acbGetColumnRange	(	const Slicer &	rowRange,
		const Slicer &	arraySection,
		ArrayBase &	arr,
		Bool	resize
	)		const

Get slices from some arrays in a column.

The first Slicer object can be used to specify start, end (or length), and stride of the rows to get. The second Slicer object can be used to specify the slice to take from each array. If the column contains n-dim arrays, the resulting array is (n+1)-dim with the last dimension representing the number of rows in the slicer. The arrays in the column must have the same shape in all those cells.

void casacore::ArrayColumnBase::acbGetSlice	(	rownr_t	rownr,
		const Slicer &	arraySection,
		ArrayBase &	array,
		Bool	resize
	)		const

Get a slice of an N-dimensional array in a particular cell (i.e.

table row). The row numbers count from 0 until #rows-1. The dimensionality of the slice must match the dimensionality of the table array and the slice definition should not exceed the shape of the table array.

void casacore::ArrayColumnBase::acbGetSlice	(	rownr_t	rownr,
		const Vector< Vector< Slice > > &	arraySlices,
		ArrayBase &	arr,
		Bool	resize
	)		const

Get an irregular slice of an N-dimensional array in a particular cell (i.e.

table row) as given by the vectors of Slice objects. The outer vector represents the array axes. A missing or empty axis means the entire axis. The inner vector represents the slices to take for each axis. For example, to get slices from 2-dim arrays:

Vector<Vector<Slice> > slices(2);      // 2-dim
slices[1].resize (3);                  // 3 slices in 2nd dim
slices[1][0] = Slice(100,20);
slices[1][1] = Slice(200,18);
slices[1][2] = Slice(538,30,2);
// Get data. Vector of first axis is empty, thus entire axis is read.
Array<Complex> data = dataCol.getColumn (slices);

If the column contains n-dim arrays, the resulting array is (n+1)-dim. with the last dimension representing the number of rows and the other dimensions representing the shape of the slice. The arrays in the column must have the same shape in all cells.

void casacore::ArrayColumnBase::acbPut	(	rownr_t	rownr,
		const ArrayBase &	array
	)

Put the array in a particular cell (i.e.

table row). The row numbers count from 0 until #rows-1. If the shape of the table array in that cell has not already been defined, it will be defined implicitly.

void casacore::ArrayColumnBase::acbPutColumn ( const ArrayBase & array )

Put the array of all values in the column.

If the column contains n-dim arrays, the source array must be (n+1)-dim with the last dimension representing the number of rows.

	)

Put into subsections of the table arrays in the entire column.

If the column contains n-dim arrays, the source array is (n+1)-dim with the last dimension representing the number of rows and other dimensions representing the shape of the slice. The dimensionality of the slice must match the dimensionality of the table array, thus must be n-dim. Also the slice definition should not exceed the shape of the table arrays.

void casacore::ArrayColumnBase::acbPutColumn	(	const Vector< Vector< Slice > > &	arraySlices,
		const ArrayBase &	arr
	)

void casacore::ArrayColumnBase::acbPutColumn ( const ArrayColumnBase & that )

void casacore::ArrayColumnBase::acbPutColumnRange	(	const Slicer &	rowRange,
		const Slicer &	arraySection,
		const ArrayBase &	arr
	)

Put into subsection of the table arrays in some rows of the column.

The first Slicer object can be used to specify start, end (or length), and stride of the rows to put. The second Slicer object can be used to specify the slice to take from each array. If the column contains n-dim arrays, the source array must be (n+1)-dim with the last dimension representing the number of rows in the slicer.

void casacore::ArrayColumnBase::acbPutSlice	(	rownr_t	rownr,
		const Slicer &	arraySection,
		const ArrayBase &	array
	)

Put into a slice of an N-dimensional array in a particular cell.

The row numbers count from 0 until #rows-1. The shape of the table array must have been defined. The dimensionality of the slice must match the dimensionality of the table array and the slice definition should not exceed the shape of the table array.

void casacore::ArrayColumnBase::acbPutSlice	(	rownr_t	rownr,

Throw an exception if the array does not have the expected shape.

However, False is returned if noSlicing and canChangeShape_p are True (meaning no slices are put and the shape of a full row can change). The column name is made part of the error message, as well as the rownr if it is not negative (meaning a put of a column).

References casacore::TableColumn::baseColPtr_p, casacore::BaseColumn::ndim(), and TABLECOLUMNCHECKROW.

ArrayColumnBase& casacore::ArrayColumnBase::operator= ( const ArrayColumnBase & )

Assignment uses reference semantics, thus works the same as function reference.

void casacore::ArrayColumnBase::reference ( const ArrayColumnBase & )

Change the reference to another column.

This is in fact an assignment operator with reference semantics. It removes the reference to the current column and creates a reference to the column referenced in the other object. It will handle null objects correctly.

void casacore::ArrayColumnBase::setShape	(	rownr_t	rownr,
		const IPosition &	shape
	)

Set the shape of the array in the given row.

Setting the shape is needed if the array is put in slices, otherwise the table system would not know the shape.

void casacore::ArrayColumnBase::setShape	(	rownr_t	rownr,
		const IPosition &	shape,
		const IPosition &	tileShape
	)

Try to store the array in a tiled way using the given tile shape.

IPosition casacore::ArrayColumnBase::shape ( rownr_t rownr ) const

inline

Get the shape of an array in a particular cell.

If the cell does not contain an array, a 0-dim shape is returned. Use the function isDefined to test if the cell contains an array.
