public class ControlFieldImpl
extends VariableFieldImpl
implements ControlField

ControlField defines behavior for a control field (tag 001-009).

Control fields are variable fields identified by tags beginning with two zero's. They are comprised of data and a field terminator and do not contain indicators or subfield codes. The structure of a control field according to the MARC standard is as follows:
