Types

type Core

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

Core represent the core logic of the match module, which include generate match transactions before packing the block, verify the match transaction in block is correct, and update the order table according to the transaction.

func NewCore

func NewCore(dbBackend, dbDir string, startBlockHeight uint64) *Core

NewCore return a instance of Core by path of mov db

func NewCoreWithDB

func NewCoreWithDB(store *database.LevelDBMovStore, startBlockHeight uint64) *Core

NewCoreWithDB return a instance of Core by movStore

func (*Core) ApplyBlock

func (m *Core) ApplyBlock(block *types.Block) error

ApplyBlock parse pending order and cancel from the the transactions of block and add pending order to the dex db, remove cancel order from dex db.

func (*Core) BeforeProposalBlock

func (m *Core) BeforeProposalBlock(block *types.Block, gasLeft int64, isTimeout func() bool) ([]*types.Tx, error)

BeforeProposalBlock return all transactions than can be matched, and the number of transactions cannot exceed the given capacity.

func (*Core) ChainStatus

func (m *Core) ChainStatus() (uint64, *bc.Hash, error)

ChainStatus return the current block height and block hash in dex core

func (*Core) DetachBlock

func (m *Core) DetachBlock(block *types.Block) error

DetachBlock parse pending order and cancel from the the transactions of block and add cancel order to the dex db, remove pending order from dex db.

func (*Core) InitChainStatus

func (m *Core) InitChainStatus(startHash *bc.Hash) error

InitChainStatus used to init the start block height and start block hash to store

func (*Core) IsDust

func (m *Core) IsDust(tx *types.Tx) bool

IsDust block the transaction that are not generated by the match engine

func (*Core) Name

func (m *Core) Name() string

Name return the name of current module

func (*Core) StartHeight

func (m *Core) StartHeight() uint64

StartHeight return the start block height of current module

func (*Core) ValidateBlock

func (m *Core) ValidateBlock(block *types.Block, verifyResults []*bc.TxVerifyResult) error

ValidateBlock no need to verify the block header, because the first module has been verified. just need to verify the transactions in the block.

func (*Core) ValidateTx

func (m *Core) ValidateTx(tx *types.Tx, verifyResult *bc.TxVerifyResult, blockHeight uint64) error

ValidateTx validate one transaction.

type Tx

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

Tx contains raw transaction and the sequence of tx in block

func NewTx

func NewTx(tx *types.Tx, blockHeight, txIndex uint64) *Tx

NewTx create a new Tx instance
