ObserverServiceBuilder provides the common functionality needed to bootstrap a Flow observer service It is composed of the FlowNodeBuilder, the ObserverServiceConfig and contains all the components and modules needed for the observers

func NewFlowObserverServiceBuilder

func NewFlowObserverServiceBuilder(opts ...Option) *ObserverServiceBuilder

func (*ObserverServiceBuilder) Build

func (builder *ObserverServiceBuilder) Build() (cmd.Node, error)

Build enqueues the sync engine and the follower engine for the observer. Currently, the observer only runs the follower engine.

func (*ObserverServiceBuilder) BuildConsensusFollower

func (builder *ObserverServiceBuilder) BuildConsensusFollower() cmd.NodeBuilder

func (*ObserverServiceBuilder) BuildExecutionSyncComponents added in v0.33.12

func (builder *ObserverServiceBuilder) BuildExecutionSyncComponents() *ObserverServiceBuilder

func (*ObserverServiceBuilder) InitIDProviders

func (builder *ObserverServiceBuilder) InitIDProviders()

func (*ObserverServiceBuilder) Initialize

func (builder *ObserverServiceBuilder) Initialize() error

func (*ObserverServiceBuilder) ParseFlags

func (builder *ObserverServiceBuilder) ParseFlags() error

type ObserverServiceConfig

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

ObserverServiceConfig defines all the user defined parameters required to bootstrap an access node For a node running as a standalone process, the config fields will be populated from the command line params, while for a node running as a library, the config fields are expected to be initialized by the caller.

func DefaultObserverServiceConfig

func DefaultObserverServiceConfig() *ObserverServiceConfig

DefaultObserverServiceConfig defines all the default values for the ObserverServiceConfig

type Option

type Option func(*ObserverServiceConfig)
