Types

type ArgsApiTransactionEvaluator

type ArgsApiTransactionEvaluator struct {
	TxTypeHandler       process.TxTypeHandler
	FeeHandler          process.FeeHandler
	TxSimulator         facade.TransactionSimulatorProcessor
	Accounts            state.AccountsAdapterWithClean

ArgsTxSimulator holds the arguments required for creating a new transaction simulator

type DataFieldParser

type DataFieldParser interface {
	Parse(dataField []byte, sender, receiver []byte, numOfShards uint32) *datafield.ResponseParseData
}

DataFieldParser defines what a data field parser should be able to do

type TransactionProcessor

type TransactionProcessor interface {
	ProcessTransaction(transaction *transaction.Transaction) (vmcommon.ReturnCode, error)
