Object
column ObjectIdentifier
An object prefix to assist an application in determining
the instance indexing to use in expValueTable, relieving the
application of the need to scan the expObjectTable to
determine such a prefix.
See expObjectTable for information on wildcarded objects.
If the expValueInstance portion of the value OID may
be treated as a scalar (that is, normally, 0) the value of
expExpressionPrefix is zero length, that is, no OID at all.
Note that zero length implies a null OID, not the OID 0.0.
Otherwise, the value of expExpressionPrefix is the expObjectID
value of any one of the wildcarded objects for the expression.
This is sufficient, as the remainder, that is, the instance
fragment relevant to instancing the values, must be the same for
all wildcarded objects in the expression.
