Detailed Description

Logic for handling tasks received from other peers or from user.

Here is class that takes requests sent (or generated locally) from queue, obtains data needed and puts results into send-queues of nodes that need to see the results.

Member Enumeration Documentation

enum NetworkRequestExecutor::NetworkRequestState

requests may be new, being processed, or ready to be sent, have enum indicating the state

Enumerator
NewRequest	NetworkRequestExecutor has not yet touched
Processing	is working in this very moment
NodeIsInWishList	node connection in progress
RequestBeingSentAround	request is sent to nodes around hash
ReadyToSend	request completed but not sent

Constructor & Destructor Documentation

NetworkRequestExecutor::NetworkRequestExecutor	(	MController *	aController,
		Model &	aModel
	)

constructor

NetworkRequestExecutor::~NetworkRequestExecutor ( )

Member Function Documentation

void NetworkRequestExecutor::doSendRequestToNode	(	NetworkRequestQueueItem &	aEntry,
		const Hash &	aNodeToSend = `KNullHash`
	)

private

method for actually sending the bytes to peer

Parameters

aEntry	is the request to send
aNodeToSend	is fingerprint of the node where to send ; if KNullHash then aEntry.iDestinationNode is used. If aNodeSend is not connected at the moment, request is simply ignored.

void NetworkRequestExecutor::nodeConnectionAttemptStatus	(	Connection::ConnectionState	aStatus,
		const Hash	aHashOfAttemptedNode
	)

slot

when connection is attempted, NetworkListener will emit the status (failed or success) of the connection, emitted signal is connected here

void NetworkRequestExecutor::processAdsClassified ( NetworkRequestQueueItem & aEntry )

private

method for producing reply to request concerning a classified ad classification -> e.g. this method sends an listing of ads to remote node, the classification of the ads match hash given in entry

void NetworkRequestExecutor::processBinaryBlob ( NetworkRequestQueueItem & aEntry )

private

method for producing reply to request concerning a binary blob -> e.g. this method sends a binary blob

void NetworkRequestExecutor::processClassifiedAd ( NetworkRequestQueueItem & aEntry )

private

method for producing reply to request concerning a classified ad -> e.g. this method sends an ad to remote node

void NetworkRequestExecutor::processNodeGreeting ( NetworkRequestQueueItem & aEntry )

private

method for sending one or more node references to given node

void NetworkRequestExecutor::processPrivateMessage ( NetworkRequestQueueItem & aEntry )

private

method for producing reply to request concerning a private msg -> e.g. this method sends a private message

void NetworkRequestExecutor::processPrivateMessagesForProfile ( NetworkRequestQueueItem & aEntry )

private

method for producing send queue items for every private message that the requesting profile has in queue.

void NetworkRequestExecutor::processRequestForBinaryBlob ( NetworkRequestQueueItem & aEntry )

private

method for requesting retrieval of a binary file

void NetworkRequestExecutor::processRequestForClassifiedAd ( NetworkRequestQueueItem & aEntry )

private

method for requesting retrieval of a binary file

void NetworkRequestExecutor::processRequestForContentPublish ( NetworkRequestQueueItem & entry )

private

method for publishing a profile+ad+binary file+profile comment

void NetworkRequestExecutor::processRequestForNodesAroundHash ( NetworkRequestQueueItem & entry )

private

method for sending nodegreeting around given hash. user initiates this and this sends around queries about nodes around given hash. the nodes that are sent the query are already-connected nodes

void NetworkRequestExecutor::processRequestForPrivateMessagePublish ( NetworkRequestQueueItem & aEntry )

private

method for publishing a private message

void NetworkRequestExecutor::processRequestForProfilePoll ( NetworkRequestQueueItem & aEntry )

private

method for requesting update of profile data and comments

void NetworkRequestExecutor::processRequestForUserProfile ( NetworkRequestQueueItem & aEntry )

private

method for requesting retrieval of a operator profile. so this means that some neighboring node sent us a request regarding a particular profile and this method then finds it from our local data store, or does not.

void NetworkRequestExecutor::processRequestForUserProfileComment ( NetworkRequestQueueItem & aEntry )

private

method for requesting retrieval of a comment of operator profile. this is called in situation where user wants to locally view a comment and it is not in local storage so we need to ask other nodes to send it to us.

void NetworkRequestExecutor::processUserProfile ( NetworkRequestQueueItem & aEntry )

private

method for producing reply to request concerning a user profile -> e.g. this method sends a profile to remote node

void NetworkRequestExecutor::processUserProfileComment ( NetworkRequestQueueItem & aEntry )

private

method for producing bytearray to send to other node containing single profile comment

void NetworkRequestExecutor::processUserProfileCommentsForProfile ( NetworkRequestQueueItem & entry )

private

method for producing reply to request concerning profile comments e.g. this method sends a profile comments whose commented profile matches the one given in the request

void NetworkRequestExecutor::run ( )

slot

this class is no thread but lets try pretending..

void NetworkRequestExecutor::sendRequestToNodesAroundHash	(	NetworkRequestQueueItem &	aEntry,
		bool	aUseContentHashNotDestination = `false`
	)

private

method for checking nodes around hash, sending request to those and if not already connected, adding those nodes to wishlist
