Constructor & Destructor Documentation

◆ Asn1Real() [1/2]

The default constructor sets the double value to zero.

◆ Asn1Real() [2/2]

Asn1Real ( double value )

This constructor creates an REAL object from a double value.

Parameters

Member Function Documentation

◆ Decode() [1/5]

void Decode	(	Asn1DecodeBuffer	buffer,
		int	length,
		int	baseflag
	)

protected

This method decodes the content octets of an ASN.1 REAL value into this object, where the REAL was encoded as for BER and the length is taken to be as given.

Note that this method is used for OER also, since OER uses the same content octets as BER, at least in certain cases.

Parameters

buffer	Decode message buffer object
length	Length of contents
baseflag	ANY_BASE: encoding may use any base ANY_BINARY: encoding may any of bases 2, 8, 16 BASE_2_ONLY: encoding may only use base 2
