Functions ¶
func ValidateManagerContext ¶
func ValidateManagerContext(mc *ManagerContext) error
Types ¶
type Manager ¶
type Manager struct {
// contains filtered or unexported fields
}
Manager manages incoming tx and coordinates with ledger manager and consensus engine.
func NewManager ¶
func NewManager(ctx *ManagerContext) *Manager
NewManager creates an instance of Manager with TxManagerContext.
func (*Manager) ApplyTxList ¶
Apply the tx list by charging fees and applying all the ops.
func (*Manager) DeleteTxList ¶
Delete tx list from the manager and update internal fields.
func (*Manager) GetTxStatus ¶
Get the status of tx.
type ManagerContext ¶
type ManagerContext struct {
NetworkID string
Database db.Database
AM *account.Manager
PM *peer.Manager
EM *exchange.Manager
BaseReserve int64
Seed string
}
ManagerContext represents contextual information TxManager needs.
type TxHistory ¶
type TxHistory struct {
// Maximum sequence number of the tx list.
MaxSeqNum uint64
// Total fees of the tx list.
TotalFees int64
// contains filtered or unexported fields
}
TxHistory is used to hold unconfirmed transactions.
func NewTxHistory ¶
func NewTxHistory() *TxHistory
func (*TxHistory) AddTx ¶
AddTx adds a transaction to pending list, note that before adding any transaction, it should be checked against signature correctness, sufficient balance of account, etc.
func (*TxHistory) DeleteTxList ¶
Delete transactions and update fields.
