Class ConstructedBERTag


public final class ConstructedBERTagextends BERTag

The ConstructedBERTag class encapsulates a constructedBER 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

Constructor Detail

ConstructedBERTag

public ConstructedBERTag()

Constructor creates an empty constructedBERTLV Tag object capable of encapsulating a constructedBER TLV Tag. All implementations must support at least 3 byte Tags which can encode tag numbers up to 0x3FFF.

Method Detail

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.


See Also:BERTag


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:initin class BERTag

Parameters:bArray - the byte array containing the binary representation

bOff - 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
