Class ConstructedBERTag

javacardx.framework.tlv.BERTag
javacardx.framework.tlv.ConstructedBERTag
@TransactionType(value=SUPPORTS)
public final class ConstructedBERTag
- extends BERTag
The ConstructedBERTag
class encapsulates a constructed BER TLV
tag. The rules on the allowed encoding of the Tag field is based on the ASN.1
BER encoding rules of ISO/IEC 8825-1:2002.
The BERTag
class and the subclasses
ConstructedBERTag
and PrimitiveBERTag
, also
provide static methods to parse or edit a BER Tag structure representation in
a byte array.
- Since:
- 2.2.2

ConstructedBERTag
public ConstructedBERTag()
- Constructor creates an empty constructed BERTLV Tag object capable of
encapsulating a constructed BER TLV Tag. All implementations must support
at least 3 byte Tags which can encode tag numbers up to 0x3FFF.
init
public void init(byte tagClass,
short tagNumber)
throws TLVException
- (Re-)Initialize
this
ConstructedBERTag
object with the specified tag class, and tag number. All implementations
must support tag numbers up to 0x3FFF.
- Parameters:
tagClass
- encodes the tag class. Valid codes listed in BER_TAG_CLASS_..
constants.tagNumber
- is the tag number.
- Throws:
TLVException
- with the following reason codes:
TLVException.ILLEGAL_SIZE
if the tag
number requested is larger than the supported maximum size
TLVException.INVALID_PARAM
if tag
class parameter is invalid or if the tag number parameter
is negative.

init
public void init(byte[] bArray,
short bOff)
throws TLVException
- (Re-)Initialize
this
ConstructedBERTag
object from the binary representation in the byte array. All
implementations must support tag numbers up to 0x3FFF.
- Specified by:
init
in class BERTag
- Parameters:
bArray
- the byte array containing the binary representationbOff
- the offset within bArray where the tag binary begins
- Throws:
ArrayIndexOutOfBoundsException
- if accessing the input array would cause access of data
outside array bounds, or if the array offset parameter is
negative
NullPointerException
- if bArray
is null
TLVException
- with the following reason codes:
TLVException.ILLEGAL_SIZE
if the tag
number requested is larger than the supported maximum size
TLVException.MALFORMED_TAG
if tag
representation in the byte array is malformed or is a
primitive array tag
