Functions

func DisableLog

func DisableLog()

DisableLog disables all library log output. Logging output is disabled by default until UseLogger is called.

func JSONFormatBlockData

func JSONFormatBlockData(data *BlockData) (*bytes.Buffer, error)

JSONFormatBlockData concatenates block data results into a single JSON object with primary keys for the result type

func NewChainMonitor

func NewChainMonitor(collector *Collector,
	savers []BlockDataSaver, reorgSavers []BlockDataSaver,
	quit chan struct{}, wg *sync.WaitGroup,
	addrs map[string]txhelpers.TxAction, blockChan chan *chainhash.Hash,
	recvTxBlockChan chan *txhelpers.BlockWatchedTx,
	reorgChan chan *ReorgData) *chainMonitor

NewChainMonitor creates a new chainMonitor

func UseLogger

func UseLogger(logger btclog.Logger)

UseLogger uses a specified Logger to output package logging info.

Types

type BlockData

type BlockData struct {
	Header           dcrjson.GetBlockHeaderVerboseResult
	Connections      int32
	FeeInfo          dcrjson.FeeInfoBlock
	CurrentStakeDiff dcrjson.GetStakeDifficultyResult
	EstStakeDiff     dcrjson.EstimateStakeDiffResult
	PoolInfo         apitypes.TicketPoolInfo
	PriceWindowNum   int
	IdxBlockInWindow int
}

BlockData contains all the data collected by a Collector and stored by a BlockDataSaver. TODO: consider if pointers are desirable here.

func (*BlockData) ToBlockSummary

func (b *BlockData) ToBlockSummary() apitypes.BlockDataBasic

ToBlockSummary returns an apitypes.BlockDataBasic object from the blockdata

func (*BlockData) ToStakeInfoExtended

func (b *BlockData) ToStakeInfoExtended() apitypes.StakeInfoExtended

ToStakeInfoExtended returns an apitypes.StakeInfoExtended object from the blockdata

func (*BlockData) ToStakeInfoExtendedEstimates

func (b *BlockData) ToStakeInfoExtendedEstimates() apitypes.StakeInfoExtendedEstimates

ToStakeInfoExtendedEstimates returns an apitypes.StakeInfoExtendedEstimates object from the blockdata

type BlockDataSaver

type BlockDataSaver interface {
	Store(data *BlockData) error
}

BlockDataSaver is an interface for saving/storing BlockData

type BlockDataToJSONFiles

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

BlockDataToJSONFiles implements BlockDataSaver interface for JSON output to the file system

func NewBlockDataToJSONFiles

func NewBlockDataToJSONFiles(folder string, fileBase string,
	m ...*sync.Mutex) *BlockDataToJSONFiles

NewBlockDataToJSONFiles creates a new BlockDataToJSONFiles with optional existing mutex

func (*BlockDataToJSONFiles) Store

func (s *BlockDataToJSONFiles) Store(data *BlockData) error

Store writes BlockData to a file in JSON format The file name is nameBase+height+".json".

type BlockDataToJSONStdOut

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

BlockDataToJSONStdOut implements BlockDataSaver interface for JSON output to stdout

func NewBlockDataToJSONStdOut

func NewBlockDataToJSONStdOut(m ...*sync.Mutex) *BlockDataToJSONStdOut

NewBlockDataToJSONStdOut creates a new BlockDataToJSONStdOut with optional existing mutex

func (*BlockDataToJSONStdOut) Store

func (s *BlockDataToJSONStdOut) Store(data *BlockData) error

Store writes BlockData to stdout in JSON format

type BlockDataToSummaryStdOut

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

BlockDataToSummaryStdOut implements BlockDataSaver interface for plain text summary to stdout

func NewBlockDataToSummaryStdOut

func NewBlockDataToSummaryStdOut(sdiffWinSize int64, m ...*sync.Mutex) *BlockDataToSummaryStdOut

NewBlockDataToSummaryStdOut creates a new BlockDataToSummaryStdOut with optional existing mutex

func (*BlockDataToSummaryStdOut) Store

func (s *BlockDataToSummaryStdOut) Store(data *BlockData) error

Store writes BlockData to stdout as plain text summary

type Collector

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

Collector models a structure for the source of the blockdata

func NewCollector

func NewCollector(dcrdChainSvr *dcrrpcclient.Client, params *chaincfg.Params,
	stakeDB *stakedb.StakeDatabase) *Collector

NewCollector creates a new Collector.

func (*Collector) Collect

func (t *Collector) Collect() (*BlockData, error)

Collect collects chain data at the current best block.

func (*Collector) CollectAPITypes

func (t *Collector) CollectAPITypes(hash *chainhash.Hash) (*apitypes.BlockDataBasic, *apitypes.StakeInfoExtended)

CollectAPITypes uses CollectBlockInfo to collect block data, then organizes it into the BlockDataBasic and StakeInfoExtended and dcrdataapi types.

func (*Collector) CollectBlockInfo

func (t *Collector) CollectBlockInfo(hash *chainhash.Hash) (*apitypes.BlockDataBasic,
	*dcrjson.FeeInfoBlock, *dcrjson.GetBlockHeaderVerboseResult, error)

CollectBlockInfo uses the chain server and the stake DB to collect most of the block data required by Collect() that is specific to the block with the given hash.
