Field Detail

TAG

public static final Asn1Tag TAG

The TAG constant describes the universal tag for this data type (UNIVERSAL 2).

mbSignExtend

protected transient boolean mbSignExtend

value

public transient java.math.BigInteger value

The value member is public and is an instance of a Java BigInteger object.

Constructor Detail

Asn1BigInteger

public Asn1BigInteger()

The default constructor sets the big integer value object reference to null.

Asn1BigInteger

public Asn1BigInteger(java.math.BigInteger value)

This constructor sets the big integer object reference to that of the object passed in.

Parameters:

value - BigInteger object reference

Asn1BigInteger

public Asn1BigInteger(java.lang.String value)

This constructor creates a new big integer object and sets it to the string value passed in. String value may contain the prefix that describes the radix: 0x - hexadecimal, 0o - octal, 0b - binary. The string value without prefix assumes decimal value. The optional sign '-' may be specified at the beginning of the string to specify the negative value.

Parameters:

value - String value

Asn1BigInteger

public Asn1BigInteger(java.lang.String value,
                      int radix)

This constructor creates a new big integer object and sets it to the number string value passed in using the given radix.

Parameters:

value - String value

Method Detail

decodeValue

public static java.math.BigInteger decodeValue(Asn1DecodeBuffer buffer,
                                               int length)
                                        throws Asn1Exception,
                                               java.io.IOException

This method decodes the contents of an ASN.1 integer value using either the Basic Encoding Rules (BER) or the Packed Encoding Rules (PER).

Parameters:

buffer - Decode message buffer object

length - Length of encoded contents

Returns:

Decoded integer value

Throws:

Asn1Exception

java.io.IOException

encodeValue

protected static int encodeValue(Asn1EncodeBuffer buffer,
                                 java.math.BigInteger ivalue,
