Types

type Conduit

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

Conduit is a helper of the overlay layer which functions as an accessor for sending messages within a single engine process. It sends all messages to what can be considered a bus reserved for that specific engine.

func (*Conduit) Close

func (c *Conduit) Close() error

func (*Conduit) Multicast

func (c *Conduit) Multicast(event interface{}, num uint, targetIDs ...flow.Identifier) error

Multicast unreliably sends the specified event to the specified number of recipients selected from the specified subset. The recipients are selected randomly from targetIDs

func (*Conduit) Publish

func (c *Conduit) Publish(event interface{}, targetIDs ...flow.Identifier) error

Publish sends an event to the network layer for unreliable delivery to subscribers of the given event on the network layer. It uses a publish-subscribe layer and can thus not guarantee that the specified recipients received the event.

func (*Conduit) ReportMisbehavior added in v0.31.0

func (c *Conduit) ReportMisbehavior(report network.MisbehaviorReport)

ReportMisbehavior reports the misbehavior of a node on sending a message to the current node that appears valid based on the networking layer but is considered invalid by the current node based on the Flow protocol. The misbehavior is reported to the networking layer to penalize the misbehaving node. The implementation must be thread-safe and non-blocking.

func (*Conduit) Unicast

func (c *Conduit) Unicast(event interface{}, targetID flow.Identifier) error

Unicast sends an event in a reliable way to the given recipient. It uses 1-1 direct messaging over the underlying network to deliver the event. It returns an error if the unicast fails.

type DefaultConduitFactory

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

DefaultConduitFactory is a wrapper around the network ConduitAdapter. It directly passes the incoming messages to the corresponding methods of the network ConduitAdapter.

func NewDefaultConduitFactory

func NewDefaultConduitFactory() *DefaultConduitFactory

NewDefaultConduitFactory creates a new DefaultConduitFactory, this is the default conduit factory used by the node. Args:

none

Returns:

a new instance of the DefaultConduitFactory.

func (*DefaultConduitFactory) NewConduit

func (d *DefaultConduitFactory) NewConduit(ctx context.Context, channel channels.Channel) (network.Conduit, error)

NewConduit creates a conduit on the specified channel. Prior to creating any conduit, the factory requires an ConduitAdapter to be registered with it.

func (*DefaultConduitFactory) RegisterAdapter

func (d *DefaultConduitFactory) RegisterAdapter(adapter network.ConduitAdapter) error

RegisterAdapter sets the ConduitAdapter component of the factory. The ConduitAdapter is a wrapper around the Network layer that only exposes the set of methods that are needed by a conduit.
