Synopsis
StManColumnArrayAipsIO handles indirect arrays in a table column.
An array (or section of an array) is only read when needed.
It, however, caches the array shape using the helper class
StIndArray. Pointers to these objects
are maintained using the standard StManColumnAipsIO facilities.
When the column gets written, the offsets in the StManArrayFile file
get written. Those will be read back when the column is read in.
When a row gets deleted or when the array gets bigger, the file space
is lost. This storage manager is a simple one and no attempts
are done to make it smart.
Member Description
Create a column of the given type.
Frees up the storage.
It can handle access to a slice in a cell.
Set the (fixed) shape of the arrays in the entire column.
Get the column shape.
Set the shape of the array in the given row and allocate the array
in the file.
Is the shape defined (i.e. is there an array) in this row?
uInt ndim (uInt rownr)
Get the dimensionality of the item in the given row.
0 is returned if there is no array.
Get the shape of the array in the given row.
An zero-length IPosition is returned if there is no array.
This storage manager can handle changing array shapes.
Get an array value in the given row.
The buffer pointed to by dataPtr has to have the correct length
(which is guaranteed by the ArrayColumn get function).

void putArrayuCharV (uInt rownr, const Array<uChar>* dataPtr)
void putArrayShortV (uInt rownr, const Array<Short>* dataPtr)
void putArrayuShortV (uInt rownr, const Array<uShort>* dataPtr)
void putArrayIntV (uInt rownr, const Array<Int>* dataPtr)
void putArrayuIntV (uInt rownr, const Array<uInt>* dataPtr)
void putArrayfloatV (uInt rownr, const Array<float>* dataPtr)
void putArraydoubleV (uInt rownr, const Array<double>* dataPtr)
void putArrayComplexV (uInt rownr, const Array<Complex>* dataPtr)
void putArrayDComplexV (uInt rownr, const Array<DComplex>* dataPtr)
void putArrayStringV (uInt rownr, const Array<String>* dataPtr)
Put an array value into the given row.
The buffer pointed to by dataPtr has to have the correct length
(which is guaranteed by the ArrayColumn put function).
Get a section of the array in the given row.
The buffer pointed to by dataPtr has to have the correct length
(which is guaranteed by the ArrayColumn getSlice function).
Put into a section of the array in the given row.
The buffer pointed to by dataPtr has to have the correct length
(which is guaranteed by the ArrayColumn putSlice function).
void remove (uInt rownr)
Remove the value in the given row.
This will result in lost file space.
Delete the array in the given row.
Data* getShape (uInt rownr)
Read the shape at the given row.
It throws an exception if undefined.
Get a pointer to the data array.
Forbid copy constructor.
MSMIndColumn& operator= (const MSMIndColumn&)
Forbid assignment.
