Functions

func GetAllSCRs

func GetAllSCRs(scProcessorAsInterface interface{}) []data.TransactionHandler

GetAllSCRs returns all generated scrs

func GetGasRemaining

func GetGasRemaining(scProcessorAsInterface interface{}) uint64

GetGasRemaining returns the remaining gas from the last transaction

func GetLatestTestError

func GetLatestTestError(scProcessorAsInterface interface{}) error

GetLatestTestError should only be used in tests! It locates the latest error in the collection of smart contracts results TODO remove this file as it is a horrible hack to test some conditions

func NewArgumentParser

func NewArgumentParser() *argumentParser

NewArgumentParser creates a full argument parser component

func NewScQueryServiceDispatcher

func NewScQueryServiceDispatcher(list []process.SCQueryService) (*scQueryServiceDispatcher, error)

NewScQueryServiceDispatcher returns a smart contract query service dispatcher that for each function call will forward the request towards the provided list in a round-robin fashion

func NewSmartContractProcessor

func NewSmartContractProcessor(args ArgsNewSmartContractProcessor) (*scProcessor, error)

NewSmartContractProcessor creates a smart contract processor that creates and interprets VM data

}

ArgsNewSmartContractProcessor defines the arguments needed for new smart contract processor

type SCQueryService

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

SCQueryService can execute Get functions over SC to fetch stored values

func NewSCQueryService

func NewSCQueryService(
	vmContainer process.VirtualMachinesContainer,
	economicsFee process.FeeHandler,
	blockChainHook process.BlockChainHookHandler,
	blockChain data.ChainHandler,
) (*SCQueryService, error)

NewSCQueryService returns a new instance of SCQueryService

func (*SCQueryService) ComputeScCallGasLimit

func (service *SCQueryService) ComputeScCallGasLimit(tx *transaction.Transaction) (uint64, error)

ComputeScCallGasLimit will estimate how many gas a transaction will consume

func (*SCQueryService) ExecuteQuery

func (service *SCQueryService) ExecuteQuery(query *process.SCQuery) (*vmcommon.VMOutput, error)

ExecuteQuery returns the VMOutput resulted upon running the function on the smart contract

func (*SCQueryService) IsInterfaceNil

func (service *SCQueryService) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface
