OSB_LIB::Asn1Info Class Reference

Collaboration diagram for OSB_LIB::Asn1Info:

[legend]List of all members.

Detailed Description

Provide information about ASN.1 data.

Attention:

data_ points to memory owned by the ASN.1 reader:
thus copying and assignment will work only as long as the reader exists and its data was not modified.

Definition at line 66 of file asn1reader.h.

Member Function Documentation

size_t OSB_LIB::Asn1Info::construct	(	const Asn1Byte *	data,
		size_t	size
	)			[private]

Construct from ASN.1 data.

Parameters:

	data	ASN.1 data: tag, length and data.
	size	Size of the ASN.1 data.

Returns:

size_t(-1) in case of an error, else the total number of bytes of the ASN.1 type.

const Asn1Byte * OSB_LIB::Asn1Info::data

long OSB_LIB::Asn1Info::filePos

(

)

const [inline]

size_t OSB_LIB::Asn1Info::getTagAndLen	(	const Asn1Byte *	data,
		size_t	size
	)			[private]

Get tag and length from input data.

Parameters:

	data	Data to use.
	size	Size of data.

Returns:

The total number of bytes the tag and length,
size_t(-1) in case of an error.

size_t OSB_LIB::Asn1Info::nextMember

(

Asn1Info &

dest

)

Determine the ASN.1 member.

Parameters:

dest

Gets the next ASN.1 member if available.

Returns:

The tag value of dest or Asn1Tag::tagNotSet if

• data_ is 0,
• all data was processed
• the ASN.1 type is not constructed.
