AbstractVariableVariable from the supplied (sub-)index.
fromSubIndex in interface VariablefromSubIndex in class AbstractVariablesubIndex - the sub-index OID.impliedLength - specifies if the sub-index has an implied length. This parameter applies
to variable length variables only (e.g. OctetString and
OID). For other variables it has no effect.
