func NewEventRetriever ¶
func NewEventRetriever(client bind.ContractBackend, filterers []model.ContractFilterers) *EventRetriever
NewEventRetriever creates a EventRetriever given a list of ContractFilterers and connection to client
func (*EventRetriever) AddFilterers ¶
func (r *EventRetriever) AddFilterers(w model.ContractFilterers) error
AddFilterers add filterers to the retriever
func (*EventRetriever) RemoveFilterers ¶
func (r *EventRetriever) RemoveFilterers(w model.ContractFilterers) error
RemoveFilterers remove given filterers from the retriever
func (*EventRetriever) Retrieve ¶
func (r *EventRetriever) Retrieve(nonSubOnly bool) error
Retrieve gets all events from StartBlock until now If nonSubOnly is true, retrieve only event types that are not subscribed to by the watchers. This is useful when polling for events alongside setting up watchers for events.
func (*EventRetriever) SortEventsByBlock ¶
func (r *EventRetriever) SortEventsByBlock(events []*model.Event) error
SortEventsByBlock sorts events in PastEvents by block number NOTE(IS): This is not optimal, but for now checking that values exist outside of sort Pass in nil if you want to sort retriever.PastEvents
