}

type BorBlockLogsFilter

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

BorBlockLogsFilter can be used to retrieve and filter logs.

func NewBorBlockLogsFilter

func NewBorBlockLogsFilter(backend Backend, borConfig *params.BorConfig, block common.Hash, addresses []common.Address, topics [][]common.Hash) *BorBlockLogsFilter

NewBorBlockLogsFilter creates a new filter which directly inspects the contents of a block to figure out whether it is interesting or not.

func NewBorBlockLogsRangeFilter

func NewBorBlockLogsRangeFilter(backend Backend, borConfig *params.BorConfig, begin, end int64, addresses []common.Address, topics [][]common.Hash) *BorBlockLogsFilter

NewBorBlockLogsRangeFilter creates a new filter which uses a bloom filter on blocks to figure out whether a particular block is interesting or not.

func (*BorBlockLogsFilter) Logs

func (f *BorBlockLogsFilter) Logs(ctx context.Context) ([]*types.Log, error)

Logs searches the blockchain for matching log entries, returning all from the first block that contains matches, updating the start of the filter accordingly.

type EventSystem

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

EventSystem creates subscriptions, processes events and broadcasts them to the subscription which match the subscription criteria.

func NewEventSystem

func NewEventSystem(backend Backend, lightMode bool) *EventSystem

NewEventSystem creates a new manager that listens for event on the given mux, parses and filters them. It uses the all map to retrieve filter changes. The work loop holds its own index that is used to forward events to filters.

The returned manager has a loop that needs to be stopped with the Stop function or by stopping the given mux.

func (*EventSystem) SubscribeLogs

func (es *EventSystem) SubscribeLogs(crit ethereum.FilterQuery, logs chan []*types.Log) (*Subscription, error)

SubscribeLogs creates a subscription that will write all logs matching the given criteria to the given logs channel. Default value for the from and to block is "latest". If the fromBlock > toBlock an error is returned.

func (*EventSystem) SubscribeNewDeposits

func (es *EventSystem) SubscribeNewDeposits(data chan *types.StateSyncData) *Subscription

func NewBlockFilter

func NewBlockFilter(backend Backend, block common.Hash, addresses []common.Address, topics [][]common.Hash) *Filter

func NewRangeFilter

func NewRangeFilter(backend Backend, begin, end int64, addresses []common.Address, topics [][]common.Hash) *Filter

NewRangeFilter creates a new filter which uses a bloom filter on blocks to figure out whether a particular block is interesting or not.

func (*Filter) Logs

func (f *Filter) Logs(ctx context.Context) ([]*types.Log, error)

Logs searches the blockchain for matching log entries, returning all from the first block that contains matches, updating the start of the filter accordingly.

type FilterCriteria

type PublicFilterAPI

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

PublicFilterAPI offers support to create and manage filters. This will allow external clients to retrieve various information related to the Ethereum protocol such als blocks, transactions and logs.

func NewPublicFilterAPI

func NewPublicFilterAPI(backend Backend, lightMode bool, timeout time.Duration, borLogs bool) *PublicFilterAPI

NewPublicFilterAPI returns a new PublicFilterAPI instance.

func (*PublicFilterAPI) GetFilterChanges

func (api *PublicFilterAPI) GetFilterChanges(id rpc.ID) (interface{}, error)

GetFilterChanges returns the logs for the filter with the given id since last time it was called. This can be used for polling.

For pending transaction and block filters the result is []common.Hash. (pending)Log filters return []Log.

https://eth.wiki/json-rpc/API#eth_getfilterchanges

func (*PublicFilterAPI) GetFilterLogs

func (api *PublicFilterAPI) GetFilterLogs(ctx context.Context, id rpc.ID) ([]*types.Log, error)

GetFilterLogs returns the logs for the filter with the given id. If the filter could not be found an empty array of logs is returned.

https://eth.wiki/json-rpc/API#eth_getfilterlogs

func (*PublicFilterAPI) GetLogs

func (api *PublicFilterAPI) GetLogs(ctx context.Context, crit FilterCriteria) ([]*types.Log, error)

GetLogs returns logs matching the given argument that are stored within the state.

https://eth.wiki/json-rpc/API#eth_getlogs

func (*PublicFilterAPI) Logs

Logs creates a subscription that fires for all new log that match the given filter criteria.

func (*PublicFilterAPI) NewBlockFilter

func (api *PublicFilterAPI) NewBlockFilter() rpc.ID

NewBlockFilter creates a filter that fetches blocks that are imported into the chain. It is part of the filter package since polling goes with eth_getFilterChanges.

https://eth.wiki/json-rpc/API#eth_newblockfilter

func (*PublicFilterAPI) NewDeposits

func (api *PublicFilterAPI) NewDeposits(ctx context.Context, crit ethereum.StateSyncFilter) (*rpc.Subscription, error)

NewDeposits send a notification each time a new deposit received from bridge.

func (*PublicFilterAPI) NewFilter

func (api *PublicFilterAPI) NewFilter(crit FilterCriteria) (rpc.ID, error)

NewFilter creates a new filter and returns the filter id. It can be used to retrieve logs when the state changes. This method cannot be used to fetch logs that are already stored in the state.

Default criteria for the from and to block are "latest". Using "latest" as block number will return logs for mined blocks. Using "pending" as block number returns logs for not yet mined (pending) blocks. In case logs are removed (chain reorg) previously returned logs are returned again but with the removed property set to true.

In case "fromBlock" > "toBlock" an error is returned.

https://eth.wiki/json-rpc/API#eth_newfilter

func (*PublicFilterAPI) NewHeads

func (api *PublicFilterAPI) NewHeads(ctx context.Context) (*rpc.Subscription, error)

func (*PublicFilterAPI) NewPendingTransactionFilter

func (api *PublicFilterAPI) NewPendingTransactionFilter() rpc.ID

NewPendingTransactionFilter creates a filter that fetches pending transaction hashes as transactions enter the pending state.

It is part of the filter package because this filter can be used through the `eth_getFilterChanges` polling method that is also used for log filters.

https://eth.wiki/json-rpc/API#eth_newpendingtransactionfilter

func (*PublicFilterAPI) NewPendingTransactions

func (api *PublicFilterAPI) NewPendingTransactions(ctx context.Context) (*rpc.Subscription, error)

NewPendingTransactions creates a subscription that is triggered each time a transaction enters the transaction pool and was signed from one of the transactions this nodes manages.

Subscription is created when the client registers itself for a particular event.

func (*Subscription) Err

func (sub *Subscription) Err() <-chan error

Err returns a channel that is closed when unsubscribed.

func (*Subscription) Unsubscribe

type Type

type Type byte

Type determines the kind of filter and is used to put the filter in to the correct bucket when added.

const (
	// UnknownSubscription indicates an unknown subscription type
	UnknownSubscription Type = iota
	// LogsSubscription queries for new or removed (chain reorg) logs
	LogsSubscription
	// PendingLogsSubscription queries for logs in pending blocks
	PendingLogsSubscription
	// MinedAndPendingLogsSubscription queries for logs in mined and pending blocks.
	MinedAndPendingLogsSubscription
	// PendingTransactionsSubscription queries tx hashes for pending
	// transactions entering the pending state
	PendingTransactionsSubscription
	// BlocksSubscription queries hashes for blocks that are imported
