Constructor & Destructor Documentation

TimeStamp::TimeStamp ( const Oidx ,
mib_access  ,
int   
)

Construct a TimeStamp.

Parameters
oidthe oid of the leaf or the column of the columnar object.
accessthe max-access rights for the object. (Normally READONLY)
valueModecontains an ored value of one or more of the following modes: VMODE_DEFAULT: the value of the object pointed by value will be used as default value, otherwise the managed object has no default value. VMODE_LOCKED: value is locked (cannot be modified) while the row status of the receiver's row is active(1). This mode has no effect, if the the leaf is a scalar or otherwise if the receiver's row has no snmpRowStatus.
