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.
