Detailed Description

Allows to parse a bytestream that conforms to the bitefficient representation of FIPA messages to a ACLMessage.

Given a bytestream that conforms to the FIPA Standard for the bitefficient representation of messages, this class can be used to parse this stream into a ACLMessage. The parsing makes extensive use of the boost::spirit library, a library whose contribution we want to acknowledge here. The Spirit library has been used to define the grammar and the underlying parser, i.e. the core of this library.

Internals: Since the parser works with a number of customized data structures to facilitate parsing, a number of function have been implemented in order to perform the conversion to the datastructure required for a ACLMessage. Yet (by August 2010), we haven't done any performance evaluation of the library.

Member Function Documentation

bool fipa::acl::BitefficientMessageParser::buildMessage	(	const Message &	parsedMsg,
		ACLMessage &	msg
	)

creates an unpopulated message object and passes it around to have its fields populated, along with the parsed message where the data is extracted from

Parameters

parsedMsg	The (intermediate) message from the spirit parser
msg	The (final) ACLMessage to be filled with the parsed data

Returns

the decoded ACLMessage object

    msg.setPerformative(parsedMsg.type);
    buildParameters(parsedMsg.parameters, msg);
    
    return true;
}

bool fipa::acl::BitefficientMessageParser::parseData ( const std::string &  storage, ACLMessage &  msg  )

virtual

parses a correctly encoded message according to grammar_bitefficient.h and creates a Message object for internal use

Parameters

storage	Array of bytes that represent the bitefficient FIPA encoded message
msg	The message extracted from the data

Returns

The decoded ACLMessage object
