}

type Config struct {
	TLS                          bool
	AuthCacheEnabled             bool
	AuthCacheMaxSize             int
	AuthCachePurgeRetentionRatio float64
}

func (Config) String

func (c Config) String() string

String returns a string representation of this Config

type ConfigSequenceSupport

type ConfigSequenceSupport interface {
	// ConfigSequence returns the configuration sequence of the a given channel
	ConfigSequence(channel string) uint64
}

ConfigSequenceSupport returns the config sequence of the given channel

type ConfigSupport

type ConfigSupport interface {
	// Config returns the channel's configuration
	Config(channel string) (*discprotos.ConfigResult, error)
}

ConfigSupport provides access to channel configuration

type EndorsementSupport

type EndorsementSupport interface {
	// PeersForEndorsement returns an EndorsementDescriptor for a given set of peers, channel, and chaincode
	PeersForEndorsement(channel common.ChannelID, interest *discprotos.ChaincodeInterest) (*discprotos.EndorsementDescriptor, error)

	// PeersAuthorizedByCriteria returns the peers of the channel that are authorized by the given chaincode interest
	// That is - taking in account if the chaincode(s) in the interest are installed on the peers, and also
	// taking in account whether the peers are part of the collections of the chaincodes.
	// If a nil interest, or an empty interest is passed - no filtering is done.
	PeersAuthorizedByCriteria(chainID common.ChannelID, interest *discprotos.ChaincodeInterest) (discovery.Members, error)
}

EndorsementSupport provides knowledge of endorsement policy selection for chaincodes

type GossipSupport interface {
	// ChannelExists returns whether a given channel exists or not
	ChannelExists(channel string) bool

	// PeersOfChannel returns the NetworkMembers considered alive
