Prerequisite

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

◆ ArrayColumnBase() [1/4]

casacore::ArrayColumnBase::ArrayColumnBase ( )

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

it does not reference a table column.

◆ ArrayColumnBase() [2/4]

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

Construct for the given column in the given table.

◆ ArrayColumnBase() [3/4]

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.

◆ ArrayColumnBase() [4/4]

casacore::ArrayColumnBase::ArrayColumnBase ( const ArrayColumnBase )

Copy constructor (reference semantics).

◆ ~ArrayColumnBase()

casacore::ArrayColumnBase::~ArrayColumnBase ( )

Member Function Documentation

◆ acbFillColumn()

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

Put the same value in all cells of the column.

◆ acbGet()

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.

◆ acbGetColumn() [1/3]

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().

◆ acbGetColumn() [2/3]

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.

◆ acbGetColumn() [3/3]

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.

◆ acbGetColumnCells() [1/3]

void casacore::ArrayColumnBase::acbGetColumnCells ( const RefRows rownrs,
ArrayBase arr,
Bool  resize 
) const

◆ acbGetColumnCells() [2/3]

◆ acbGetColumnRange() [1/2]

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

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.

◆ acbGetColumnRange() [2/2]

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.

◆ acbGetSlice() [1/2]

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.

◆ acbGetSlice() [2/2]

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.

◆ acbPut()

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.

◆ acbPutColumn() [1/4]

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.

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

◆ acbPutColumn() [2/4]

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

Put the contents of that column into this one.

◆ acbPutColumn() [3/4]

void casacore::ArrayColumnBase::acbPutColumn ( const Slicer arraySection,
const ArrayBase 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.

◆ acbPutColumn() [4/4]

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

◆ acbPutColumnRange() [1/2]

void casacore::ArrayColumnBase::acbPutColumnRange ( const Slicer rowRange,
const ArrayBase 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.

◆ acbPutColumnRange() [2/2]

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.

◆ acbPutSlice() [1/2]

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.

◆ acbPutSlice() [2/2]

void casacore::ArrayColumnBase::acbPutSlice ( rownr_t  rownr,
const Vector< Vector< Slice > > &  arraySlices,

ArrayBase arr,
Bool  resize,
Int64  rownr,
const String where 
) const

If the array is empty or if resize=True, the array is resized if needed. Otherwise checkShape is used to throw an exception if not conforming.

◆ baseGet()

void casacore::ArrayColumnBase::baseGet ( rownr_t  rownr,
ArrayBase array 
) const
inline

Counterparts of the acbGet() functions below not checking shapes, etc.

They are faster and can be used for performance reasons if one knows for sure that the arguments are correct. E.g., they are used internally in virtual column engines.

Definition at line 132 of file ArrayColumnBase.h.

References casacore::array(), casacore::TableColumn::baseColPtr_p, and casacore::BaseColumn::getArray().

◆ baseGetSlice()

void casacore::ArrayColumnBase::baseGetSlice ( rownr_t  rownr,
const Slicer arraySection,
ArrayBase array 
) const
inline

◆ basePut()

void casacore::ArrayColumnBase::basePut ( rownr_t  rownr,
const ArrayBase array 
)
inline

Counterparts of the acbPut() functions below not checking shapes, etc.

They are faster and can be used for performance reasons if one knows for sure that the arguments are correct. E.g., they are used internally in virtual column engines.

Definition at line 260 of file ArrayColumnBase.h.

References casacore::array(), casacore::TableColumn::baseColPtr_p, and casacore::BaseColumn::putArray().

◆ basePutSlice()

void casacore::ArrayColumnBase::basePutSlice ( rownr_t  rownr,
const Slicer arraySection,
const ArrayBase array 
)
inline

◆ checkShape()

Bool casacore::ArrayColumnBase::checkShape ( const IPosition expShape,
const IPosition arrShape,
Bool  noSlicing,
Int64  rownr,
const String where 
) const

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).

◆ handleSlices()

void casacore::ArrayColumnBase::handleSlices ( const Vector< Vector< Slice > > &  slices,
BaseSlicesFunctor functor,
const Slicer slicer,
const ArrayBase array 
) const

A common function used by all functions that can get or put irregular array slices.

The functor performs the get or put operation.

◆ ndim()

uInt casacore::ArrayColumnBase::ndim ( rownr_t  rownr) const
inline

Get the #dimensions of an array in a particular cell.

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

Definition at line 118 of file ArrayColumnBase.h.

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

◆ operator=()

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

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

◆ 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.

◆ setShape() [1/2]

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.
