Detailed Description

ASN.1 bit string control class. The ASN1CBitStr class is derived from the ASN1CType base class. It is used as the base class for generated control classes for the ASN.1 BIT STRING type. This class provides utility methods for operating on the bit string referenced by the generated class. This class can also be used inline to operate on bits within generated BIT STRING elements in a SEQUENCE, SET, or CHOICE construct.

Constructor & Destructor Documentation

◆ ASN1CBitStr() [1/2]

EXTRTMETHOD ASN1CBitStr::ASN1CBitStr	(	OSRTMessageBufferIF &	msgbuf,
		OSSIZE	nbits
	)

This constructor creates an empty bit string. If the nbits argument is zero, the bit string is set to be dynamic; otherwise, the capacity is set to nbits.

Parameters

msgbuf	- ASN.1 message buffer or stream object.
nbits	- Number of bits this bit string can contain (zero if unbounded.

◆ ASN1CBitStr() [2/2]

EXTRTMETHOD ASN1CBitStr::ASN1CBitStr	(	OSRTMessageBufferIF &	msgbuf,
		OSOCTET *	bitStr,
		OSUINT32 &	numbits,
		OSSIZE	maxNumbits_,
		OSOCTET **	ppExtData = `0`
	)

This constructor creates a bit string from an array of bits. The constructor does not copy the bit string data, it just references the given data variables. All operations on the bit string cause the referenced items to be updated directly.

Parameters

msgbuf	- ASN.1 message buffer or stream object.
bitStr	- Pointer to static byte array
numbits	- Reference to length of bit string (in bits)
maxNumbits_	- sets maximum length in bits
