Types

type FlowContext 

type FlowContext struct {
	// contains filtered or unexported fields
}

FlowContext holds state that is relevant to more than one flow or one peer, and allows communication between different flows that can be associated to different peers.

func (*FlowContext) AddToPeers 

func (f *FlowContext) AddToPeers(peer *peerpkg.Peer) error

func (*FlowContext) EnqueueTransactionIDsForPropagation 

func (f *FlowContext) EnqueueTransactionIDsForPropagation(transactionIDs []*externalapi.DomainTransactionID) error

EnqueueTransactionIDsForPropagation add the given transactions IDs to a set of IDs to propagate. The IDs will be broadcast to all peers within a single transaction Inv message. The broadcast itself may happen only during a subsequent call to this method

func (f *FlowContext) IsOrphan(blockHash *externalapi.DomainHash) bool

IsOrphan returns whether the given blockHash belongs to an orphan block

func (*FlowContext) IsRecoverableError 

func (*FlowContext) IsRecoverableError(err error) bool

IsRecoverableError returns whether the error is recoverable

func (*FlowContext) NetAdapter 

func (f *FlowContext) NetAdapter() *netadapter.NetAdapter
