62 // ISMColumn represents a Column in the Incremental Storage Manager.
63 // </etymology>
64 
65 // <synopsis>
66 // ISMColumn handles the access to a column containing scalars or direct
67 // arrays of the various data types. It uses class <linkto class=ISMBucket>
68 // ISMBucket</linkto> to get and put the data into the correct bucket.
69 // When the value does not fit in the bucket, the bucket is split
70 // and the new bucket is added to the storage manager.
71 // <p>
72 // The object maintains a variable indicating the last row ever put.
73 // This is used to decide if a put of a value is valid until the
74 // end of the table or for that one row only. In this way it does not
75 // make any difference if rows are added before or after a value is put
76 // <br>
77 // A value put before or at the last row ever put will only affect that
78 // one row. The rows before and after it keep their original value. If
79 // needed that value is copied.
80 // <p>
81 // To optimize (especially sequential) access to the column, ISMColumn
82 // maintains the last value gotten and the rows for which it is valid.
83 // In this way a get does not need to access the data in the bucket.
84 // <p>
85 // ISMColumn use the static conversion functions in the
86 // <linkto class=Conversion>Conversion</linkto> framework to
87 // get/put the data in external format (be it canonical or local).
88 // Most data types are fixed length, but some are variable length
89 // (e.g. String). In external format variable length data is preceeded
90 // by its total length (which includes the length itself). This makes
91 // it possible to get the length of a data value without having to
92 // interpret it, which is easy when (re)moving a value. For this reason
93 // ISMColumn contains its own conversion functions for Strings.
94 // <p>
95 // ISMColumn also acts as the base class for more specialized ISM
96 // column classes (i.e. <linkto class=ISMIndColumn>ISMIndColumn</linkto>
97 // for indirect columns).
98 // In this way <linkto class=ISMBase>ISMBase</linkto> can hold a
99 // block of <src>ISMColumn*</src> for any column. Furthermore
100 // <src>ISMColumn</src> contains the hooks to allow a derived class
101 // to use other ISMColumn functions (e.g. there are "action" functions
102 // for a derived class to react on the duplication or removal of
103 // a data value (e.g. due to a bucket split).
104 // </synopsis>
105
