virtual void MockUpNodeModel::addNodeFromBroadcast	(	const Hash &	aNodeFingerPrint,
		const QHostAddress &	aAddr,
		int	aPort
	)

virtual

method for adding node reference from broadcast. this needs difference in handling because in IPv4 network this typically contains private addr space addresses that we don't want to permanently store nor give to others as node-references.

For making connections inside LANs of organisations having NATs and firewalls and whatnot this might still be a handy feature.

Implements MNodeModelProtocolInterface.

virtual bool MockUpNodeModel::addNodeToConnectionWishList ( Node * aNode )

virtual

method for adding a node to connection-wishlist. network connector engine will then later pick them up. nodemodel will take ownership of the node and delete the object later.

Implements MNodeModelProtocolInterface.

virtual bool MockUpNodeModel::addNodeToConnectionWishList ( const Hash & aNode )

virtual

method for adding a node to connection-wishlist. network connector engine will then later pick them up.

Implements MNodeModelProtocolInterface.

virtual Hash MockUpNodeModel::bucketEndHash ( const Hash & aFingerPrintOfNodeAsking )

virtual

Important method regarding churn here. This is called from Connection class and this method is used to determine what content belongs to same bucket with the node that is being served by that Connection. Content in the same bucket with the node is then sent over to node ; to keep the content alive in the network.

Intent here is find bucket size where we have approximately 20 live nodes in a bucket.

This is done so that we order the recently-seen nodes by hash value of the node, then start from the fingerprint of the node that is asking, and from that point we count to 20. The fingerprint of the node at position 20 is the end of the bucket. The fingerprint of the node that asks is the start.

Parameters

aFingerPrintOfNodeAsking fingerprint of node that wants to have its bucket filled

Returns: Ending-address of the nodes bucket.
