Method Details

pack

public byte[] pack(ISOComponent c)
            throws ISOException

Description copied from class: ISOBasePackager

pack method that works in conjunction with ISOBasePackager.unpack(ISOComponent, byte[]).

Handles a tertiary bitmap possibly appearing in Data Element thirdBitmapField.

Specified by:

pack in interface ISOPackager

Overrides:

pack in class ISOBasePackager

Parameters:

c - the Component to pack

Returns:

Message image

Throws:

ISOException - if the component cannot be packed

unpack

public int unpack(ISOComponent m,
 byte[] b)
           throws ISOException

Description copied from interface: ISOPackager

Unpacks an ISO-8583 byte array into the given message container.

Specified by:

unpack in interface ISOPackager

Overrides:

unpack in class ISOBasePackager

Parameters:

m - the Container of this message

b - ISO message image

Returns:

consumed bytes

Throws:

ISOException - if the message image cannot be unpacked

emitBitMap

protected boolean emitBitMap()

Always return false.

Overrides:

emitBitMap in class ISOBasePackager

Returns:

true if the field-1 packager is an ISOBitMapPackager

validate

public ISOComponent validate(ISOComponent c)
                      throws ISOException

Description copied from interface: ISOValidator

Specified by:

validate in interface ISOValidator

Overrides:

validate in class ISOBaseValidatingPackager

Parameters:

c - the ISO component to validate
