Read and write access to an array table column with arbitrary data type.
Public interface
ArrayColumn<T> gives read and write access to an column in a table containing an array with data type T.
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.
See module Tables.

| 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.

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.
| 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.
| 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.
| void casacore::ArrayColumn< T >::putColumn | ( | const Vector< Vector< Slice > > & | arraySlices, |
| const Array< T > & | arr | ||
| ) |
| 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.
| void casacore::ArrayColumn< T >::putColumnCells | ( | const RefRows & | rownrs, |
| const Array< T > & | arr | ||

| void casacore::ArrayColumn< T >::putColumnCells | ( | const RefRows & | rownrs, |

| void casacore::ArrayColumn< T >::putColumnCells | ( | const RefRows & | rows, |
| const Vector< Vector< Slice > > & | arraySlices, | ||
| const Array< T > & | arr | ||
| ) |
Same as putColumn(arraySlices, arr) except that it puts for the given rows instead of all rows.
| void casacore::ArrayColumn< T >::putColumnCells | ( | const RefRows & | rows, |
| const ColumnSlicer & | columnSlicer, | ||
| const Array< T > & | source | ||
| ) |
| 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.
| 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.
| void casacore::ArrayColumn< T >::putSlice | ( | uInt | rownr, |
| const Slicer & | arraySection, | ||
| const Array< T > & | 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::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.
Referenced by casacore::ArrayColumn< casacore::String >::attach().
| void casacore::ArrayColumn< T >::setShape | ( | uInt | 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::ArrayColumn< T >::setShape | ( | uInt | rownr, |
| const IPosition & | shape, | ||
| const IPosition & | tileShape | ||
| ) |
Try to store the array in a tiled way using the given tile shape.
|
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.
