Types

type PeerConfiger

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

PeerConfiger implements the configuration handler for the peer. For every configuration transaction coming in from the ordering service, the committer calls this system chaincode to process the transaction.

func (*PeerConfiger) Init

Init is called once per chain when the chain is created. This allows the chaincode to initialize any variables on the ledger prior to any transaction execution on the chain.

func (*PeerConfiger) Invoke

Invoke is called for the following: # to process joining a chain (called by app as a transaction proposal) # to get the current configuration block (called by app) # to update the configuration block (called by commmitter) Peer calls this function with 2 arguments: # args[0] is the function name, which must be JoinChain, GetConfigBlock or UpdateConfigBlock # args[1] is a configuration Block if args[0] is JoinChain or UpdateConfigBlock; otherwise it is the chain id TODO: Improve the scc interface to avoid marshal/unmarshal args
