OID::OID ( word32  v )

inline

Construct an OID.

Parameters

v	value to initialize the OID

Member Function Documentation

void OID::BERDecode

(

BufferedTransformation &

bt

)

BER decode an OID.

Parameters

bt	BufferedTransformation object

Definition at line 268 of file asn.cpp.

Here is the call graph for this function:

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);
