Types ¶
type Action ¶
type Action struct {
// Type of the action
Type ActionType
// EntityID of the instance in action
EntityID EntityID
// ModelName of the instance in action
ModelName string
// Previous is the instance before the action
Previous interface{}
// Current is the instance after the action was done
Current interface{}
}
Action is a operation done in the model
type ActionType ¶
type ActionType int
ActionType is the type used by actions done in a txn
const ( // Create indicates the creation of an instance in a txn Create ActionType = iota // Save indicates the mutation of an instance in a txn Save // Delete indicates the deletion of an instance by ID in a txn Delete )
type EventCodec ¶
type EventCodec interface {
// Reduce applies generated events into state
Reduce(events []Event, datastore ds.TxnDatastore, baseKey ds.Key) ([]ReduceAction, error)
// Create corresponding events to be dispatched
Create(ops []Action) ([]Event, format.Node, error)
// EventsFromBytes deserializes a format.Node bytes payload into
// Events.
EventsFromBytes(data []byte) ([]Event, error)
}
EventCodec transforms actions generated in models to events dispatched to thread logs, and viceversa.
type ReduceAction ¶
type ReduceAction struct {
// Type of the reduced action
Type ActionType
// Model in which action was made
Model string
// EntityID of the instance in reduced action
