Etymology

ISMColumn represents a Column in the Incremental Storage Manager.

Synopsis

ISMColumn handles the access to a column containing scalars or direct arrays of the various data types. It uses class ISMBucket to get and put the data into the correct bucket. When the value does not fit in the bucket, the bucket is split and the new bucket is added to the storage manager.

The object maintains a variable indicating the last row ever put. This is used to decide if a put of a value is valid until the end of the table or for that one row only. In this way it does not make any difference if rows are added before or after a value is put
A value put before or at the last row ever put will only affect that one row. The rows before and after it keep their original value. If needed that value is copied.

To optimize (especially sequential) access to the column, ISMColumn maintains the last value gotten and the rows for which it is valid. In this way a get does not need to access the data in the bucket.

ISMColumn use the static conversion functions in the Conversion framework to get/put the data in external format (be it canonical or local). Most data types are fixed length, but some are variable length (e.g. String). In external format variable length data is preceeded by its total length (which includes the length itself). This makes it possible to get the length of a data value without having to interpret it, which is easy when (re)moving a value. For this reason ISMColumn contains its own conversion functions for Strings.

ISMColumn also acts as the base class for more specialized ISM column classes (i.e. ISMIndColumn for indirect columns). In this way ISMBase can hold a block of ISMColumn* for any column. Furthermore ISMColumn contains the hooks to allow a derived class to use other ISMColumn functions (e.g. there are "action" functions for a derived class to react on the duplication or removal of a data value (e.g. due to a bucket split).

Motivation

ISMColumn encapsulates all operations on an ISM Column.
