Types

type Options

type Options struct {
	Limit           int
	LimitPerAccount int
	MaxLifetime     time.Duration
}

Options options for tx pool.

type TxEvent

}

TxEvent will be posted when tx is added or status changed.

type TxPool

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

TxPool maintains unprocessed transactions.

var (
	GlobTxPoolInst *TxPool
)

func GetGlobTxPoolInst

func GetGlobTxPoolInst() *TxPool

func New

func New(chain *chain.Chain, stateCreator *state.Creator, options Options) *TxPool

New create a new TxPool instance. Shutdown is required to be called at end.

func (*TxPool) Add

func (p *TxPool) Add(newTx *tx.Transaction) error

Add add new tx into pool. It's not assumed as an error if the tx to be added is already in the pool,

func (*TxPool) Close

func (p *TxPool) Close()

Close cleanup inner go routines.

func (*TxPool) Dump

func (p *TxPool) Dump() tx.Transactions

Dump dumps all txs in the pool.

func (*TxPool) Executables

func (p *TxPool) Executables() tx.Transactions

Executables returns executable txs.

func (*TxPool) Fill

func (p *TxPool) Fill(txs tx.Transactions)

Fill fills txs into pool.

func (*TxPool) Get

func (p *TxPool) Get(id meter.Bytes32) *tx.Transaction

func (*TxPool) Remove

func (p *TxPool) Remove(txID meter.Bytes32) bool

Remove removes tx from pool by its ID.

func (*TxPool) StrictlyAdd

func (p *TxPool) StrictlyAdd(newTx *tx.Transaction) error

StrictlyAdd add new tx into pool. A rejection error will be returned, if tx is not executable at this time.

func (*TxPool) SubscribeTxEvent

func (p *TxPool) SubscribeTxEvent(ch chan *TxEvent) event.Subscription

SubscribeTxEvent receivers will receive a tx
