StArrAipsIO.h

StManColumnArrayAipsIO holds the direct arrays in memory and writes them into the AipsIO file when the table gets closed. It fully supports addition and removal of rows. When a row is added to the table, the direct array gets allocated. This is possible, because the shape of direct arrays is known.

The class is derived from StManColumnAipsIO which is used to hold a pointer to the array.

Motivation

StManColumnArrayAipsIO handles the standard data types. The class is not templated, but a switch statement is used instead. Templates would cause too many instantiations.

To Do

Maybe TpArrayInt, etc. should be used instead of TpInt.
get/putSlice use too many array operations. To solve this requires an array constructor taking a pointer to the data (which is foreseen in the new Array classes).
