Method Detail

emitBitMap

protected boolean emitBitMap()

Always return false

Overrides:

emitBitMap in class ISOBasePackager

Returns:

true if BitMap have to be emited

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 - on error

unpack

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

This packager treats field 0 as a field that may or may not be present before the TLV subelements. Certain types of messages for some 8583 specs that extend this class' behavior (e.g., the Mastercard implementation in class MasterCardEBCDICSubFieldPackager) may not have field 0 present (the TCC in Mastercard's nomenclature). So, if the corresponding isofield packager for field 0 doesn't fill the ISOComponent's value, we don't store anything as subfield 0 of m.

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 - on error
