Detailed Description

Information about ASN.1 tags.

The class provides information about an ASN.1 tag:

• the name (description) of the tag
• the decoder for primitive ASN.1 types
• list of sub-types for constructed ASN.1 types.

Definition at line 72 of file asn1tagdes.h.

Constructor & Destructor Documentation

OSB_LIB::Asn1TagDes::Asn1TagDes

(

const Asn1Tag &

tag = Asn1Tag()

)

[explicit]

Constructor with optional ASN.1 tag.

---

Member Function Documentation

void OSB_LIB::Asn1TagDes::add

(

const SubTypes &

subTypes

)

Add a list of subtypes.

void OSB_LIB::Asn1TagDes::add

(

const Asn1TagDes &

subDes

)

Add the description for a subtype.

void OSB_LIB::Asn1TagDes::buildFrom

(

Asn1Info &

asn1

)

Construct from ASN.1 information.

Parameters:

asn1

ASN.1 information to process.

Decoder OSB_LIB::Asn1TagDes::decoder

(

)

const

Get the decoder function.

If decoder_ is not set it is taken from Asn1Print.

Returns:

The decoder function, 0 in case of an unknown decoder.
Callers may use Asn1Print::prRaw() in the latter case.

const std::string OSB_LIB::Asn1TagDes::decoderName

(

)

const

Name of decoder function.

static Asn1TagDes* OSB_LIB::Asn1TagDes::find	(	SubTypes &	src,
		const Asn1Tag &	tag
	)			[static]

Find the description for an ASN.1 tag.

Parameters:

	src	List of ASN.1 description to search.
	tag	ASN.1 tag to find.

Returns:

Pointer to the description for tag, 0 if the tag is not in src.

void OSB_LIB::Asn1TagDes::moveOut	(	SubTypes &	dest,
		int	level
	)

Reduce indentation of sub-types.

void OSB_LIB::Asn1TagDes::print	(	std::ostream &	os,
		const std::string &	indent = ""
	)			const

Print the definition to a stream.

Parameters:

	os	Stream to write to.
	indent	Indent of the lines, incremented by 2 spaces for each member.

Prints the tag description in format of Asn1DesParser.

void OSB_LIB::Asn1TagDes::setDecoderName

(

const std::string &

decoderName

)

Set the name of the decoder function.

bool OSB_LIB::Asn1TagDes::setDecoders

(

std::set< std::string > &

errors

)

Set the decoder function.

Uses decoderName() to retrieve and set decoder_ from Asn1Print for itself and all subtypes.

Parameters:

errors

Gets unknown decoders.

Returns:

true if all decoders could be determined, else false.

const SubTypes& OSB_LIB::Asn1TagDes::subTypes

(

)

const

Get descriptions of sub-types.

For primitive types the list is normally empty.
