Prerequisite

Etymology

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

Synopsis

The class ArrayColumn allows readonly access to a column containing arrays with an arbitrary data type. It can handle direct as well as indirect arrays. It is possible to get the data in an individual cell (i.e. table row); either the whole array or a slice of the array can be accessed. It is also possible to get the column as a whole if the arrays in all cells of the column have the same shape (which is always true for direct arrays). As in the case of individual cells it is possible to get the entire arrays or a slice of the arrays.

A default constructor is defined to allow construction of an array of ArrayColumn objects. However, this constructs an object not referencing a column. Functions like get, etc. will fail (i.e. result in a segmentation fault) when used on such objects. The functions isNull and throwIfNull can be used to test on this. The functions attach and reference can fill in the object.

The assignment operator is not defined for this class, because it was felt it would be too confusing. Instead the function reference can be used to do assignment with reference semantics. An assignment with copy semantics makes no sense for a readonly column.

Constructor & Destructor Documentation

template<class T>
casacore::ArrayColumn< T >::ArrayColumn ( )

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

it does not reference a table column. The sole purpose of this constructor is to allow construction of an array of ArrayColumn objects. The functions reference and attach can be used to make a null object reference a column. Note that get functions, etc. will cause a segmentation fault when operating on a null object. It was felt it was too expensive to test on null over and over again. The user should use the isNull or throwIfNull function in case of doubt.

template<class T>
casacore::ArrayColumn< T >::ArrayColumn ( const Table ,
const String columnName 
)

Construct for the given column in the given table.

template<class T>
casacore::ArrayColumn< T >::ArrayColumn ( const TableColumn )
explicit

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.

template<class T>
casacore::ArrayColumn< T >::ArrayColumn ( const ArrayColumn< T > &  )

Copy constructor (reference semantics).

Member Function Documentation

template<class T>
void casacore::ArrayColumn< T >::attach ( const Table table,
const String columnName 
)
inline

Attach a column to the object.

This is in fact only a shorthand for
reference (ArrayColumn<T> (table, columnName));

Definition at line 146 of file ArrayColumn.h.

template<class T>
void casacore::ArrayColumn< T >::checkDataType ( ) const
private

Check if the data type matches the column data type.

template<class T>
virtual TableColumn* casacore::ArrayColumn< T >::clone ( ) const
virtual

Clone the object.

Reimplemented from casacore::TableColumn.

template<class T>
void casacore::ArrayColumn< T >::fillColumn ( const Array< T > &  value)

Put the same value in all cells of the column.

template<class T>
void casacore::ArrayColumn< T >::get ( rownr_t  rownr,
Array< T > &  array,
Bool  resize = False 
) const

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

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

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the table array shape. However, if the resize flag is set the destination array will be resized if not conforming.

Array<T> casacore::ArrayColumn< T >::get ( rownr_t  rownr) const
template<class T>
void casacore::ArrayColumn< T >::getColumn ( Array< T > &  array,
Bool  resize = False 
) 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.

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

template<class T>
void casacore::ArrayColumn< T >::getColumn ( const Slicer arraySection,
Array< T > &  array,
Bool  resize = False 
) 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.

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

template<class T>
void casacore::ArrayColumn< T >::getColumn ( const Vector< Vector< Slice > > &  arraySection,
Array< T > &  array,
Bool  resize = False 
) 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.

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

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. According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

) 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. According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

) const
template<class T>
void casacore::ArrayColumn< T >::getSlice ( rownr_t  rownr,
const Slicer arraySection,
Array< T > &  array,
Bool  resize = False 
) 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.

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the shape of the table array slice. However, if the resize flag is set the destination array will be resized if not conforming.

void casacore::ArrayColumn< T >::getSlice ( rownr_t  rownr,
const Vector< Vector< Slice > > &  arraySlices,
Array< T > &  arr,
Bool  resize = False 
) 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.

According to the assignment rules of class Array, the destination array must be empty or its shape must conform the resulting (n+1)-dim array. However, if the resize flag is set the destination array will be resized if not conforming.

Array<T> casacore::ArrayColumn< T >::operator() ( rownr_t  rownr) const
template<class T>
ArrayColumn<T>& casacore::ArrayColumn< T >::operator= ( const ArrayColumn< T > &  )

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

template<class T>
void casacore::ArrayColumn< T >::put ( rownr_t  rownr,
const Array< T > &  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.

template<class T>
void casacore::ArrayColumn< T >::put ( rownr_t  rownr,
const TableColumn that,
Bool  preserveTileShape = False 
)
inline

Copy the value of a cell of that column to a cell of this column.

This function uses a generic TableColumn object as input. The data types of both columns must be the same, otherwise an exception is thrown.

Use the same row numbers for both cells.

Use possibly different row numbers for that (i.e.

input) and and this (i.e. output) cell.

Reimplemented from casacore::TableColumn.

template<class T>
void casacore::ArrayColumn< T >::put ( uInt  thisRownr,
const TableColumn that,
uInt  thatRownr,

template<class T>
void casacore::ArrayColumn< T >::putColumn ( const Array< T > &  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.

template<class T>
void casacore::ArrayColumn< T >::putColumn ( const Slicer arraySection,
const Array< T > &  array 
)

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.

template<class T>
void casacore::ArrayColumn< T >::putColumn ( const Vector< Vector< Slice > > &  arraySlices,
const Array< T > &  arr 
)
template<class T>
void casacore::ArrayColumn< T >::putColumn ( const ArrayColumn< T > &  that)

Put the contents of a column with the same data type into this column.

To put the contents of a column with a different data type into this column, the function TableColumn::putColumn can be used (provided the data type promotion is possible). In fact, this function is an assignment operator with copy semantics.

template<class T>
void casacore::ArrayColumn< T >::putColumnCells ( const RefRows rows,
const Vector< Vector< Slice > > &  arraySlices,

template<class T>
void casacore::ArrayColumn< T >::putColumnRange ( const Slicer rowRange,
const Array< T > &  arr 
)

Put the array of some values in the column.

The Slicer object can be used to specify start, end (or length), and stride of the rows to put. 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.

template<class T>
void casacore::ArrayColumn< T >::putColumnRange ( const Slicer rowRange,
const Slicer arraySection,
const Array< T > &  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.

template<class T>
void casacore::ArrayColumn< T >::putSlice ( rownr_t  rownr,

template<class T>
void casacore::ArrayColumn< T >::reference ( const ArrayColumn< T > &  )

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.

template<class T>
void casacore::ArrayColumn< T >::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.

template<class T>
void casacore::ArrayColumn< T >::setShape ( rownr_t  rownr,
const IPosition shape,
const IPosition tileShape 
)

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

template<class T>
IPosition casacore::ArrayColumn< T >::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.
