type StateListener added in v1.1.0

type StateListener interface {

	HandleStateUpdates(trigger *StateUpdateTrigger) error
	StateCommitDone(channelID string)
}

StateListener allows a custom code for performing additional stuff upon state change for a perticular namespace against which the listener is registered. This helps to perform custom tasks other than the state updates. A ledger implemetation is expected to invoke Function `HandleStateUpdates` once per block and the `stateUpdates` parameter passed to the function captures the state changes caused by the block for the namespace. The actual data type of stateUpdates depends on the data model enabled. For instance, for KV data model, the actual type would be proto message `github.com/hyperledger/fabric/protos/ledger/rwset/kvrwset.KVWrite` Function `HandleStateUpdates` is expected to be invoked before block is committed and if this function returns an error, the ledger implementation is expected to halt block commit operation and result in a panic

type StateUpdateTrigger added in v1.3.0

type StateUpdateTrigger struct {
	LedgerID                    string
