An Indirect String Array Column in the Standard Storage Manager.
Internal
SSMIndStringColumn represents an Indirect String Array Column in the Standard Storage Manager.
SSMIndStringColumn handles indirect variable shaped string arrays. Note that indirect fixed shape string arrays are handled by SSMDirColumn .
All string array access is handled by class SSMStringHandler , so SSMIndStringColumn is merely an interface to this class. The only thing it does is accessing the bucketnr, offset, and length in the data bucket.
The reason that indirect string arrays are handled here instead of in SSMIndColumn is that the string buckets are more disk space efficient when string arrays are frequently updated.
Definition at line 86 of file SSMIndStringColumn.h.
Create a SSMIndStringColumn object with the given parent.
It initializes the various variables. It keeps the pointer to its parent (but does not own it).
