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 (  ) 

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

Asn1BigInteger ( BigInteger  value  ) 

This constructor assigns a big integer object.

Parameters:
value BigInteger value
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:
value String value
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:
value String value
radix Can be 16 for hexadecimal, 8 for octal, 2 for binary or 10 for decimal

upper The PER-visible upper bound; null if there is not an upper bound.
override void Decode ( Asn1PerDecodeBuffer  buffer  )  [virtual]

This method decodes an unconstrained ASN.1 integer value using the Packed Encoding Rules (PER). The length and contents components of the message are decoded. The decoded result is stored in the public mValue member variable.

Reimplemented from Asn1Type.

override void Encode ( Asn1BerOutputStream  outs,
bool  explicitTagging 
) [virtual]

This method encodes and writes to the stream an ASN.1 integer value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER).

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters:

Member Data Documentation

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).

Reimplemented from Asn1Type.

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.
