func NewMemoryPool 

func NewMemoryPool() *MemoryPool

NewMemoryPool creates a new MemoryPool

func (*MemoryPool) CommitUpdate 

func (p *MemoryPool) CommitUpdate(transactionData []tms.TransactionData) error

CommitUpdate commits transaction data into the pool.

func (*MemoryPool) HistoryIterator 

func (p *MemoryPool) HistoryIterator() *HistoryIterator

func (p *MemoryPool) Iterator() *PoolIterator

Iterator returns an iterator of the unspent outputs based on a copy of the pool.

func (*MemoryPool) OutputByID 

func (p *MemoryPool) OutputByID(id string) (*token.PlainOutput, error)

OutputByID gets an output by its ID.

func (*MemoryPool) TxByID 

func (p *MemoryPool) TxByID(txID string) (*token.TokenTransaction, error)

TxByID gets a transaction by its transaction ID. If no transaction exists with the given ID, a TxNotFoundError is returned.

type OutputNotFoundError 

type OutputNotFoundError struct {
	ID string
}

OutputNotFoundError is returned when an entry was not found in the pool.

func (*OutputNotFoundError) Error
