Member Function Documentation

static int balber::BerUtil_LengthImpUtil::getLength	(	int *	result,
		int *	accumNumBytesConsumed,
		bsl::streambuf *	streamBuf
	)			[static]

Decode the length octets from the specified streamBuf and load the result to the specified result. If the length is indefinite (i.e., contents will be terminated by "end-of-content" octets) then result will be set to k_INDEFINITE_LENGTH. Add the number of bytes consumed to the specified accumNumBytesConsumed. Return 0 on success, and a non-zero value otherwise.

static int balber::BerUtil_LengthImpUtil::getEndOfContentOctets	(	int *	accumNumBytesConsumed,
		bsl::streambuf *	streamBuf
	)			[static]

Decode the "end-of-content" octets (two consecutive zero-octets) from the specified streamBuf and add the number of bytes consumed (which is always 2) to the specified accumNumBytesConsumed. Return 0 on success, and a non-zero value otherwise.

static int balber::BerUtil_LengthImpUtil::putLength	(	bsl::streambuf *	streamBuf,
		int	length
	)			[static]

Encode the specified length length octets to the specified streamBuf. Return 0 on success, and a non-zero value otherwise. The behavior is undefined unless 0 <= length.

static int balber::BerUtil_LengthImpUtil::putIndefiniteLengthOctet

(

bsl::streambuf *

streamBuf

)

[static]

Encode the "indefinite-length" octet onto the specified streamBuf. This octet signifies that the length of the contents is indefinite (i.e., contents will be terminated by end of content octets). Return 0 on success, and a non-zero value otherwise.

static int balber::BerUtil_LengthImpUtil::putEndOfContentOctets

(

bsl::streambuf *

streamBuf

)

[static]

Encode the identifier octets for the specified tagClass, tagType and tagNumber to the specified streamBuf. Return 0 on success, and a non-zero value otherwise.
