A column of Standard storage manager for indirect arrays.
Internal
SSMIndColumn represents a Column in the Standard Storage Manager containing Indirect arrays.
SSMIndColumn is the implementation of an SSMColumn class to handle indirect arrays. The arrays (shape and data) are stored in a separate file using class StIndArray. The file offset of the beginning of the array in stored in the appropriate data bucket using the standard SSMColumn functions.
Note that an indirect array can have a fixed shape. In that case adding a row results in reserving space for the array in the StIndArray file, so for each row an array is present. On the other hand adding a row does nothing for variable shaped arrays. So when no data is put or shape is set, a row may contain no array at all. In that case the function isShapeDefined returns False for that row.
Indirect arrays containing strings are not handled by this class, but by SSMIndStringColumn. That class stores those string arrays in the special string buckets instead of using StIndArray. The reason is that the string buckets are more disk space efficient when string arrays are frequently updated.
