Functions

func NewValidator

func NewValidator(
	channelID string,
	sem Semaphore,
	cr ChannelResources,
	ler LedgerResources,
	lcr plugindispatcher.LifecycleResources,
	cor plugindispatcher.CollectionResources,
	pm plugin.Mapper,
	channelPolicyManagerGetter policies.ChannelPolicyManagerGetter,
	cryptoProvider bccsp.BCCSP,
) txvalidator.Validator

NewValidator returns a new block validator. If using V2 validation and distributed validation is enabled then the distributed validator is used. Distributed validation is not supported for V14 validation.

Types

type ChannelResources

type ChannelResources interface {
	// MSPManager returns the MSP manager for this channel
	MSPManager() msp.MSPManager

	// Apply attempts to apply a configtx to become the new config
	Apply(configtx *common.ConfigEnvelope) error

	// GetMSPIDs returns the IDs for the application MSPs
	// that have been defined in the channel
	GetMSPIDs() []string

	// Capabilities defines the capabilities for the application portion of this channel
	Capabilities() channelconfig.ApplicationCapabilities

	// Ledger returns the ledger associated with this validator
	Ledger() ledger.PeerLedger
}

ChannelResources provides access to channel artefacts or functions to interact with them

type LedgerResources

type LedgerResources interface {
	// GetTransactionByID retrieves a transaction by id
	GetTransactionByID(txID string) (*peer.ProcessedTransaction, error)

	// NewQueryExecutor gives handle to a query executor.
	// A client can obtain more than one 'QueryExecutor's for parallel execution.
	// Any synchronization should be performed at the implementation level if required
	NewQueryExecutor() (ledger.QueryExecutor, error)
}

LedgerResources provides access to ledger artefacts or functions to interact with them

type Semaphore

type Semaphore interface {
	// Acquire implements semaphore-like acquire semantics
	Acquire(ctx context.Context) error

	// Release implements semaphore-like release semantics
	Release()
}

Semaphore provides to the validator means for synchronisation
