DecodeFromCBORObject

public void DecodeFromCBORObject(com.upokecenter.cbor.CBORObject obj)
                          throws CoseException

Description copied from class: Message

Given a CBOR tree, parse the message. This is an abstract function that is implemented for each different supported COSE message.

Specified by:

DecodeFromCBORObject in class Message

Parameters:

obj - CBORObject to be converted to a message.

Throws:

CoseException

EncodeCBORObject

protected com.upokecenter.cbor.CBORObject EncodeCBORObject()
                                                    throws CoseException

Description copied from class: Message

Encode the COSE message object to a CBORObject tree. This function call will force cryptographic operations to be executed as needed. This is an internal function, as such it does not add the tag on the front and is implemented on a per message object.

Specified by:

EncodeCBORObject in class Message

Returns:

CBORObject representing the message.

Throws:

CoseException
