Constructor Detail

CBEFFDataGroup

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

Creates a CBEFF data group.

Parameters:

dataGroupTag - the data group tag

subRecords - the sub-records contained in this data group

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)

Adds a record to this data group.

Parameters:

record - the record to add

addAll

public void addAll(List<R> records)

Adds all records in a list to this data group.

Parameters:

records - the records to add

remove

public void remove(int index)

Removes the record at the given index.

Parameters:

index - the index of the record to remove

toString

public String toString()

Returns a textual representation of this data group.

Overrides:

toString in class DataGroup

Returns:

a textual representation of this data group

getSubRecords

public List<R> getSubRecords()

Returns the records in this data group.

Returns:

the records in this data group

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

getEncoded

public byte[] getEncoded()

Returns the contents of this file as byte array, includes the ICAO tag and length.

Specified by:

getEncoded in interface LDSElement

Returns:

a byte array containing the file
