	Version   = "0.1.0" // software version

)

var DdchainBlockTime = 5 * time.Second

DdchainBlockTime Block time of DDChain

var SWVersion, _ = semver.Make(Version)

func (ConstantName) String

func (cn ConstantName) String() string

String implement fmt.stringer

type ConstantVals

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

ConstantVals implement ConstantValues interface

func NewConstantValue

func NewConstantValue() *ConstantVals

NewConstantValue get new instance of ConstantValue

func (*ConstantVals) GetBoolValue

func (cv *ConstantVals) GetBoolValue(name ConstantName) bool

GetBoolValue retrieve a bool constant value from the map

func (*ConstantVals) GetInt64Value

func (cv *ConstantVals) GetInt64Value(name ConstantName) int64

GetInt64Value get value in int64 type, if it doesn't exist then it will return the default value of int64, which is 0

func (*ConstantVals) GetStringValue

func (cv *ConstantVals) GetStringValue(name ConstantName) string

GetStringValue retrieve a string const value from the map

func (ConstantVals) MarshalJSON

func (cv ConstantVals) MarshalJSON() ([]byte, error)

MarshalJSON marshal result to json format

func (*ConstantVals) String

func (cv *ConstantVals) String() string

type ConstantValues

type ConstantValues interface {
	fmt.Stringer
	GetInt64Value(name ConstantName) int64
