Class CBEFFDataGroup<R extends BiometricDataBlock>

java.lang.Object

org.jmrtd.lds.AbstractTaggedLDSFile

org.jmrtd.lds.DataGroup

org.jmrtd.lds.CBEFFDataGroup<R>

Type Parameters:

R - the type of the elements

All Implemented Interfaces:

Serializable, LDSElement, LDSFile

Direct Known Subclasses:

DG2File, DG3File, DG4File

public abstract class CBEFFDataGroup<R extends BiometricDataBlock>
extends DataGroup

Constructor Detail

CBEFFDataGroup

protected CBEFFDataGroup(int dataGroupTag,
                         List<R> subRecords)

CBEFFDataGroup

protected CBEFFDataGroup(int dataGroupTag,
                         InputStream inputStream)
                  throws IOException

Constructs an instance.

Parameters:

dataGroupTag - the datagroup tag to use

inputStream - an input stream

Throws:

IOException - on error

Method Detail

add

public void add(R record)

addAll

public void addAll(List<R> records)

remove

public void remove(int index)

getSubRecords

public List<R> getSubRecords()

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

writeOptionalRandomData

protected void writeOptionalRandomData(OutputStream outputStream)
                                throws IOException

Concrete implementations of EAC protected CBEFF DataGroups should call this method at the end of their AbstractTaggedLDSFile.writeContent(OutputStream) method to add some random data if the record contains zero biometric templates. See supplement to ICAO Doc 9303 R7-p1_v2_sIII_0057.

Parameters:

outputStream - the outputstream

Throws:

IOException - on I/O errors
