sgns::crdt::DAGSyncer¶

A DAGSyncer is an abstraction to an IPLD-based p2p storage layer. A DAGSyncer is a DAGService with the ability to publish new ipld nodes to the network, and retrieving others from it.

using LinkInfoPair¶

using LinkInfoSet¶

using sgns::crdt::DAGSyncer::LinkInfoSet = std::set<LinkInfoPair>;

Public Functions Documentation¶

function HasBlock¶

virtual outcome::result< bool > HasBlock(
    const CID & cid
) const =0

Parameters:

cid Content identifier of the node

Return: true if the block is locally available or outcome::failure on error

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::HasBlock

Check if the block with cid is locally available (therefore, it is considered processed).

function GetNodeWithoutRequest¶

virtual outcome::result< std::shared_ptr< ipfs_lite::ipld::IPLDNode > > GetNodeWithoutRequest(
    const CID & cid
) const =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::GetNodeWithoutRequest

function TraverseCIDsLinks¶

virtual std::pair< LinkInfoSet, LinkInfoSet > TraverseCIDsLinks(
    ipfs_lite::ipld::IPLDNode & node,
    std::string link_name,
    LinkInfoSet visited_links
) const =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::TraverseCIDsLinks

function InitCIDBlock¶

virtual void InitCIDBlock(
    const CID & cid
) =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::InitCIDBlock

function IsCIDInCache¶

virtual bool IsCIDInCache(
    const CID & cid
) const =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::IsCIDInCache

function DeleteCIDBlock¶

virtual outcome::result< void > DeleteCIDBlock(
    const CID & cid
) =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::DeleteCIDBlock

function Stop¶

virtual void Stop() =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::Stop

function markResolved¶

virtual IPFS::outcome::result< void > markResolved(
    const CID & cid
) =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::markResolved

function isResolved¶

virtual IPFS::outcome::result< bool > isResolved(
    const CID & cid
) const =0

Reimplemented by: sgns::crdt::GraphsyncDAGSyncer::isResolved
