Types

type Initializer

type Initializer interface {
	Proposer

	Resources
}

Initializer is used as indirection between Manager and Handler to allow for single Handlers to handle multiple paths

type Manager

type Manager interface {
	Resources

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

	// Validate attempts to apply a configtx to become the new config
	Validate(configEnv *cb.ConfigEnvelope) error

	// Validate attempts to validate a new configtx against the current config state
	ProposeConfigUpdate(configtx *cb.Envelope) (*cb.ConfigEnvelope, error)

	// ChainID retrieves the chain ID associated with this manager
	ChainID() string

	// ConfigEnvelope returns the current config envelope
	ConfigEnvelope() *cb.ConfigEnvelope

	// Sequence returns the current sequence number of the config
	Sequence() uint64
}

Manager provides a mechanism to query and update config

type PolicyHandler

type PolicyHandler interface {
	Transactional

	BeginConfig(tx interface{}, groups []string) ([]PolicyHandler, error)

	ProposePolicy(tx interface{}, key string, path []string, policy *cb.ConfigPolicy) (proto.Message, error)
}

PolicyHandler is used for config updates to policy

type Proposer

type Proposer interface {
	// ValueProposer return the root value proposer
	ValueProposer() config.ValueProposer

	// PolicyProposer return the root policy proposer
	PolicyProposer() policies.Proposer
}

Proposer contains the references necesssary to appropriately unmarshal a cb.ConfigGroup

type Resources

type Resources interface {
	// PolicyManager returns the policies.Manager for the channel
	PolicyManager() policies.Manager

	// ChannelConfig returns the config.Channel for the chain
	ChannelConfig() config.Channel

	// OrdererConfig returns the config.Orderer for the channel
	// and whether the Orderer config exists
	OrdererConfig() (config.Orderer, bool)

	// ConsortiumsConfig() returns the config.Consortiums for the channel
	// and whether the consortiums config exists
	ConsortiumsConfig() (config.Consortiums, bool)

	// ApplicationConfig returns the configtxapplication.SharedConfig for the channel
	// and whether the Application config exists
	ApplicationConfig() (config.Application, bool)

	// MSPManager returns the msp.MSPManager for the chain
	MSPManager() msp.MSPManager
}

Resources is the common set of config resources for all channels Depending on whether chain is used at the orderer or at the peer, other config resources may be available

type Transactional

type Transactional interface {
	// RollbackConfig called when a config proposal is abandoned
	RollbackProposals(tx interface{})

	// PreCommit verifies that the transaction can be committed successfully
	PreCommit(tx interface{}) error

	// CommitConfig called when a config proposal is committed
	CommitProposals(tx interface{})
}

Transactional is an interface which allows for an update to be proposed and rolled back
