megaco_codec_mstone2(3erl)				     Erlang Module Definition					megaco_codec_mstone2(3erl)

NAME

       megaco_codec_mstone2 - This module implements a simple megaco codec-based performance tool.

DESCRIPTION

       This module implements the mstone2 tool, a simple megaco codec-based performance tool.

       The results, the mstone value(s), are written to stdout.

       Note that this module is not included in the runtime part of the application.

EXPORTS

       start() -> void()
       start(MessagePackage) -> void()

	      Types  MessagePackage = message_package()
		     message_package() = atom()

	      This  function  starts the mstone2 performance test with all codec configs. Processes are created dynamically. Each process make one
	      run through their messages (decoding and encoding messages) and then exits. When one process exits, a new is created with  the  same
	      codec config and set of messages.

	      The number of messages processed in total (for all processes) is the mstone value.

NAME

       megaco_encoder - Megaco encoder behaviour.

DESCRIPTION

       The following functions should be exported from a megaco_encoder callback module:

DATA TYPES

       megaco_message() = #'MegacoMessage{}'
       transaction() = {transactionRequest,	transaction_request()}	    |
		       {transactionPending,	transaction_reply()}	    |
		       {transactionReply,	transaction_pending()}	    |
		       {transactionResponseAck, transaction_response_ack()} |
		       {segmentReply,		segment_reply()}
       transaction_request() = #'TransactionRequest'{}
       transaction_pending() = #'TransactionPending'{}
       transaction_reply() = #'TransactionReply'{}
       transaction_response_ack() = [transaction_ack()]
       transaction_ack() = #'TransactionAck'{}
       segment_reply() = #'SegmentReply'{}
       action_request() = #'ActionRequest'{}
       action_reply() = #'ActionReply'{}

EXPORTS

       Module:encode_message(EncodingConfig, Version, Message) -> {ok, Bin} | Error

	      Types  EncodingConfig = list()
		     Version = integer()
		     Message = megaco_message()
		     Bin = binary()
		     Error = term()

	      Encode a megaco message.

       Module:decode_message(EncodingConfig, Version, Bin) -> {ok, Message} | Error

	      Types  EncodingConfig = list()
		     Version = integer() | dynamic
		     Message = megaco_message()
		     Bin = binary()
		     Error = term()

	      Decode a megaco message.

	      Note  that  if the Version argument is dynamic , the decoder should try to figure out the actual version from the message itself and
	      then use the proper decoder, e.g. version 1.
	      If on the other hand the Version argument is an integer, it means that this is the expected version of the message and  the  decoder
	      for that version should be used.

       Module:decode_mini_message(EncodingConfig, Version, Bin) -> {ok, Message} | Error

	      Types  EncodingConfig = list()
		     Version = integer() | dynamic
		     Message = megaco_message()
		     Bin = binary()
		     Error = term()

	      Perform a minimal decode of a megaco message.

	      The  purpose  of	this function is to do a minimal decode of Megaco message. A successfull result is a 'MegacoMessage' in which only
	      version and mid has been initiated. This function is used by the megaco_messenger module when the decode_message/3 function fails to
	      figure out the mid (the actual sender) of the message.

	      Note again that a successfull decode only returns a partially initiated message.

       Module:encode_transaction(EncodingConfig, Version, Transaction) -> OK | Error

	      Types  EncodingConfig = list()
		     Version = integer()
		     Transaction = transaction()
		     OK = {ok, Bin}
		     Bin = binary()
		     Error = {error, Reason}
		     Reason = not_implemented | OtherReason
		     OtherReason = term()

	      Encode  a megaco transaction. If this, for whatever reason, is not supported, the function should return the error reason not_imple-
	      mented .

	      This functionality is used both when the transaction sender is used and for segmentation. So, for either	of  those  to  work,  this
	      function must be fully supported!

       Module:encode_action_requests(EncodingConfig, Version, ARs) -> OK | Error

	      Types  EncodingConfig = list()
		     Version = integer()
		     ARs = action_requests()
		     action_requests() = [action_request()]
		     OK = {ok, Bin}
		     Bin = binary()
		     Error = {error, Reason}
		     Reason = not_implemented | OtherReason
		     OtherReason = term()

	      Encode megaco action requests. This function is called when the user calls the function encode_actions/3 . If that function is never
	      used or if the codec cannot support this (the encoding of individual actions), then return with error reason not_implemented .

       Module:encode_action_reply(EncodingConfig, Version, AR) -> OK | Error

	      Types  EncodingConfig = list()
		     Version = integer()
		     AR = action_reply()
		     OK = {ok, Bin}
		     Bin = binary()
		     Error = {error, Reason}
		     Reason = not_implemented | OtherReason
		     OtherReason = term()

	      Encode a megaco action reply. If this, for whatever reason, is not supported, the function should return the error reason not_imple-
	      mented .

	      This function is used when segmentation has been configured. So, for this to work, this function must be fully supported!
