Detailed Description

This class represents an ASN.1 INTEGER built-in type. In this case, the values can be greater than 64 bits in size. This class is used in generated source code if the <bigInteger> qualifier is specified in a compiler configuration file.

Constructor & Destructor Documentation

◆ Asn1BigInteger() [1/4]

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

◆ Asn1BigInteger() [2/4]

This constructor assigns a big integer object.

Parameters
valueBigInteger value

◆ Asn1BigInteger() [3/4]

Asn1BigInteger ( System.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
valueString value

◆ Asn1BigInteger() [4/4]

Asn1BigInteger ( System.String  value,
int  radix 
)

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
valueString value
radixCan be 16 for hexadecimal, 8 for octal, 2 for binary or 10 for decimal

Member Data Documentation

◆ _TAG

new readonly Asn1Tag _TAG = new Asn1Tag(Asn1Tag.UNIV, Asn1Tag.PRIM, Asn1Type.INTEGER)
static

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

◆ mValue

BigInteger mValue

The magnitude of this Asn1BigInteger, in big-endian order: the zeroth element of this array is the most-significant int of the magnitude. The magnitude must be "minimal" in that the most-significant int (mValue[0]) must be non-zero. This is necessary to ensure that there is exactly one representation for each Asn1BigInteger value. Note that this implies that the Asn1BigInteger zero has a zero-length mValue array.
