Class PrimitiveBERTag

public final class PrimitiveBERTagextends BERTag

The PrimitiveBERTag class encapsulates a primitive 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.

Constructor Detail

PrimitiveBERTag

public PrimitiveBERTag()

Constructor creates an empty PrimitiveBERTag object capable of encapsulating a primitive BER 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 PrimitiveBERTag 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 BERTAG_CLASS_* constants.

tagNumber - is the tag number.

Throws: TLVException - with the following reason codes:



See Also:BERTag

init

public void init(byte[] bArray, short bOff) throws TLVException

(Re-)Initialize this PrimitiveBERTLV Tag 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 representation

bOff - the offset within bArray where the tag binary value 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:
