I is a wrapper for I generating an array of elements |
82
|
|
|
|
|
|
|
values from the deltas raw data. It returns an array reference if |
83
|
|
|
|
|
|
|
deltas is defined, otherwise undef. |
84
|
|
|
|
|
|
|
|
85
|
|
|
|
|
|
|
Unpacking deltas raw data into elements is part of the resultset API, |
86
|
|
|
|
|
|
|
as different implementations may employ different packing mechanisms. |
