Detailed Description

Object Identifier.

Definition at line 166 of file asn.h.

Constructor & Destructor Documentation

OID() [1/2]

OID::OID ( word32  v )

inline

Construct an OID.

Parameters

v	value to initialize the OID

Definition at line 175 of file asn.h.

OID() [2/2]

OID::OID ( BufferedTransformation &  bt )

inline

Construct an OID.

Parameters

bt	BufferedTransformation object

Definition at line 178 of file asn.h.

Member Function Documentation

operator+=()

OID& OID::operator+= ( word32  rhs )

inline

Append a value to an OID.

Parameters

rhs	the value to append

Definition at line 182 of file asn.h.

DEREncode()

void OID::DEREncode

(

BufferedTransformation &

bt

)

const

DER encode this OID.

Parameters

bt	BufferedTransformation object

Definition at line 259 of file asn.cpp.

BERDecode()

void OID::BERDecode

(

BufferedTransformation &

bt

)

BER decode an OID.

Parameters

bt	BufferedTransformation object

Definition at line 271 of file asn.cpp.

BERDecodeAndCheck()

void OID::BERDecodeAndCheck

(

BufferedTransformation &

bt

)

const

BER decode an OID.

Parameters

bt	BufferedTransformation object

Exceptions

BERDecodeErr()

if decoded value doesn't match an expected OID

BERDecodeAndCheck() can be used to parse an OID and verify it matches an expected.

  BERSequenceDecoder key(bt);
  ...
  BERSequenceDecoder algorithm(key);
  GetAlgorithmID().BERDecodeAndCheck(algorithm);

Friends And Related Function Documentation

operator==

bool operator== ( const OID &  lhs, const OID &  rhs  )

friend

Compare two OIDs for equality.

Parameters

lhs	the first OID
rhs	the second OID

Returns

true if the OIDs are equal, false otherwise

operator!=

bool operator!= ( const OID &  lhs, const OID &  rhs  )

friend

Compare two OIDs for inequality.

Parameters

lhs	the first OID
rhs	the second OID

Returns

true if the OIDs are not equal, false otherwise

operator<

bool operator< ( const OID &  lhs, const OID &  rhs  )

friend

Compare two OIDs for ordering.

Parameters

lhs	the first OID
rhs	the second OID

Returns

true if the first OID is less than the second OID, false otherwise

operator<() calls std::lexicographical_compare() on each element in the array of values.
