Public Methods
	BigNumber ()
	Default constructor, for creating an object to be unmarshalled.
	BigNumber (BIGNUM *pBN)
	Create a BigNumber from a BIGNUM, taking ownership of the memory.
	BigNumber (const ASN1_INTEGER *asn1)
	Create a BigNumber from an ASN1_INTEGER.
	BigNumber (const BigNumber &aBN)
	Create a BigNumber from another BigNumber, copying the memory.
virtual	~BigNumber ()
	Destructor -- frees the stored BIGNUM and ASN1_INTEGER.
void	operator= (const BigNumber &aBN)
	Assignment operator.
void	operator= (BIGNUM *pBN)
	Assignment operator for BIGNUM%s(takes ownership of argument).
bool	operator== (const BigNumber &aBN) const
	Equality operator.
bool	operator!= (const BigNumber &aBN) const
	Inequality operator.
bool	operator< (const BigNumber &aBN) const
	Less-than operator.
bool	operator> (const BigNumber &aBN) const
	Less-than operator.
const BIGNUM *	value () const
	Returns: BIGNUM structure
const ASN1_INTEGER *	asn1 () const
	Returns: ASN1_INTEGER corresponding to the BIGNUM
int	marshal (unsigned char **pp) const
	This function creates a serialized representation of the object, which is returned through the argument pp.
void *	unmarshal (void *bogus, unsigned char **pp, long length)
	This function takes a serialized representation of the object and recreates the object representation.
Protected Attributes
BIGNUM *	m_value
	BigNumber as an OpenSSL BIGNUM.
ASN1_INTEGER *	m_asn1
	BigNumber as an ASN.1 integer.

int BigNumber::marshal (  unsigned char **    pp )  const [virtual]

This function creates a serialized representation of the object, which is returned through the argument pp. This must be overridden by the concrete derived class. Parameters: pp  Serialized form of the object Returns: Length of the marshalled data Implements CODEX_ASN1::Base. Definition at line 145 of file BigNumber.cc. References asn1(), and m_asn1.

void * BigNumber::unmarshal (  void *    bogus, unsigned char **    pp, long    length )  [virtual]

This function takes a serialized representation of the object and recreates the object representation. This must be overridden by the concrete derived class. Parameters: bogus  Included for compatibility with OpenSSL ASN.1 macros pp  Serialized form of the data length  Number of bytes of pp to unmarshal Returns: success or failure of the unmarshalling Implements CODEX_ASN1::Base.
