}

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

This implementation is designed for testing purposes.

func NewMapLedger() *MapLedger

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

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

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

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

type SimpleView struct {
	Parent *SimpleView
	Ledger *MapLedger
}

SimpleView provides a simple view for testing purposes.

func NewSimpleView() *SimpleView

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

returns all the registers that has been touched
