public final class **PrimitiveBERTag**extends [[javacard:java-card-api:BERTag|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.




**Since:**
  2.2.2

^ 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 [[javacard:java-card-api:TLVException|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:**
[[javacard:java-card-api:TLVException|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 [[javacard:java-card-api:TLVException|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:**[[javacard:java-card-api:BERTag#init(byte[], short)|init]]  in class [[javacard:java-card-api:BERTag|BERTag]]  
 

 
 


**Parameters:**bArray - the byte array containing the binary representation 
 
bOff - the offset within bArray where the tag binary value begins
 
 
**Throws:**
[[javacard:java-card-api:ArrayIndexOutOfBoundsException|ArrayIndexOutOfBoundsException]]  - if accessing the input array
 would cause access of data outside array bounds, or if the array offset
 parameter is negative
 
 
[[javacard:java-card-api:NullPointerException|NullPointerException]]  - if bArray is null
 
 
[[javacard:java-card-api:TLVException|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 
 \\
