Functions

func FilterContractEvents

func FilterContractEvents(events []types.Event, eventName, eventValue string) ([]types.Event, error)

FilterContractEvents returns events that includes a given event name and value. (value is optional)

func GetContractEventsFromResultTx

func GetContractEventsFromResultTx(contractAddr common.Address, result *ctypes.ResultTx) ([]types.Event, error)

GetContractEventsFromResultTx returns events that matches a given contract address from ResultTx.

func MakeEntryBytes

func MakeEntryBytes(name, value string) ([]byte, error)

func MakeEventSearchQuery

func MakeEventSearchQuery(contractAddr common.Address, eventName, eventValue string) (string, error)

MakeEventSearchQuery returns a query for searching events on transaction contractAddr: target contract address eventName: event name eventValue: value corresponding to event name. NOTE: if value has a prefix "0x", value will be decoded into []byte
