The rules on the allowed encoding of the Tag, length and value fields are based on the ASN.1 BER encoding rules ISO/IEC 8825-1:2002. <p> The <CODE>BERTLV</CODE> class and the subclasses - <CODE>ConstructedBERTLV</CODE> and <CODE>PrimitiveBERTLV</CODE> only support encoding of the length(L) octets in definite form. These classes do not provide support for the encoding rules of the contents octets of the value(V) field as described in ISO/IEC 8825-1:2002. <p> The <CODE>BERTLV</CODE> class and the subclasses - <CODE>ConstructedBERTLV</CODE> and <CODE>PrimitiveBERTLV</CODE> also provide static methods to parse/edit a TLV structure representation in a byte array.<P><P><DL><DT><B>Since:</B></DT>
