Class ISOVField

java.lang.Object

org.jpos.iso.ISOComponent

org.jpos.iso.ISOField

org.jpos.iso.ISOVField

All Implemented Interfaces:

Externalizable, Serializable, Cloneable, ISOVErrorList

public class ISOVField
extends ISOField
implements ISOVErrorList

Wrapper class resulting from process of validating an ISOField instance. Contains details of the original field and validation-error details too. Normally in validation process when an error is detected by validator in some field, then the field is replaced by an instance of this class, containning error details.
