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.

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:
- 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 PrimitiveBERTLV Tag 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 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:
- TLVException.ILLEGAL_SIZE if the tag number is larger than the supported maximum size
- TLVException.MALFORMED_TAG if tag representation in the byte array is malformed or is a constructed array tag
