Types

type MapLedger

type MapLedger struct {
	Registers       map[string]flow.RegisterEntry
	RegisterTouches map[string]bool
	RegisterUpdated map[string]bool
}

A MapLedger is a naive ledger storage implementation backed by a simple map.

This implementation is designed for testing purposes.

func NewMapLedger

func NewMapLedger() *MapLedger

NewMapLedger returns an instance of map ledger (should only be used for testing)

func (*MapLedger) Delete

func (m *MapLedger) Delete(owner, controller, key string) error

func (*MapLedger) Get

func (m *MapLedger) Get(owner, controller, key string) (flow.RegisterValue, error)

func (*MapLedger) Set

func (m *MapLedger) Set(owner, controller, key string, value flow.RegisterValue) error

func (*MapLedger) Touch

func (m *MapLedger) Touch(owner, controller, key string) error

type SimpleView

type SimpleView struct {
	Parent *SimpleView
	Ledger *MapLedger
}

SimpleView provides a simple view for testing purposes.

func NewSimpleView

func NewSimpleView() *SimpleView

func (*SimpleView) AllRegisters

func (v *SimpleView) AllRegisters() []flow.RegisterID

returns all the registers that has been touched

func (*SimpleView) Delete

func (v *SimpleView) Delete(owner, controller, key string) error

func (*SimpleView) DropDelta

func (v *SimpleView) DropDelta()

func (*SimpleView) Get

func (v *SimpleView) Get(owner, controller, key string) (flow.RegisterValue, error)

func (*SimpleView) MergeView

func (v *SimpleView) MergeView(o state.View) error

func (*SimpleView) NewChild

func (v *SimpleView) NewChild() state.View

func (*SimpleView) RegisterUpdates

func (v *SimpleView) RegisterUpdates() ([]flow.RegisterID, []flow.RegisterValue)

func (*SimpleView) Set

func (v *SimpleView) Set(owner, controller, key string, value flow.RegisterValue) error

func (*SimpleView) Touch

func (v *SimpleView) Touch(owner, controller, key string) error
