Types ¶
type Command ¶
type Command interface {
// Apply runs the commands
Apply() error
// Encode returns a serialized representation of the command
Encode() ([]byte, error)
}
Command instances represent actions to be taken by the fabric controller. They are serializable, so they can be shipped from one controller for RAFT coordination
type CreateEntityCommand ¶
type CreateEntityCommand[T models.Entity] struct { Creator EntityCreator[T] Entity T PostCreateHook func(tx *bbolt.Tx, entity T) error }
func (*CreateEntityCommand[T]) Apply ¶
func (self *CreateEntityCommand[T]) Apply() error
func (*CreateEntityCommand[T]) Encode ¶
func (self *CreateEntityCommand[T]) Encode() ([]byte, error)
type Decoders ¶
type Decoders interface {
Register(id int32, decoder Decoder)
RegisterF(id int32, decoder DecoderF)
Decode(data []byte) (Command, error)
GetDecoder(id int32) Decoder
Clear()
}
func GetDefaultDecoders ¶
func GetDefaultDecoders() Decoders
func NewDecoders ¶
func NewDecoders() Decoders
type DeleteEntityCommand ¶
type DeleteEntityCommand struct {
Deleter EntityDeleter
Id string
}
func (*DeleteEntityCommand) Apply ¶
func (self *DeleteEntityCommand) Apply() error
func (*DeleteEntityCommand) Encode ¶
func (self *DeleteEntityCommand) Encode() ([]byte, error)
type Dispatcher ¶
Dispatcher instances will take a command and either send it to the leader to be applied, or if the current system is the leader, apply it locally
type EntityCreator ¶
type EntityCreator[T models.Entity] interface { EntityMarshaller[T] // ApplyCreate creates the entity described by the given command ApplyCreate(cmd *CreateEntityCommand[T]) error }
EntityCreator instances can apply a create entity command to create entities of a given type
type EntityDeleter ¶
type EntityDeleter interface {
GetEntityTypeId() string
// ApplyDelete deletes the entity described by the given command
ApplyDelete(cmd *DeleteEntityCommand) error
}
EntityDeleter instances can apply a delete entity command to delete entities of a given type
type EntityManager ¶
type EntityManager[T models.Entity] interface { EntityCreator[T] EntityUpdater[T] EntityDeleter }
EntityManager instances can handle create, update and delete entities of a specific type
type EntityMarshaller ¶
type EntityMarshaller[T any] interface { // GetEntityTypeId returns the entity type id. This is distinct from the Store entity id // which may be shared by types, such as service and router. The entity type is unique // for each type GetEntityTypeId() string // Marshall marshals the entity to a bytes encoded format Marshall(entity T) ([]byte, error) // Unmarshall unmarshalls the bytes back into an entity Unmarshall(bytes []byte) (T, error) }
EntityMarshaller instances can marshal and unmarshal entities of the type that they manage as well as knowing their entity type
type EntityUpdater ¶
type EntityUpdater[T models.Entity] interface { EntityMarshaller[T] // ApplyUpdate updates the entity described by the given command ApplyUpdate(cmd *UpdateEntityCommand[T]) error }
EntityUpdater instances can apply an update entity command to update entities of a given type
type LocalDispatcher ¶
type LocalDispatcher struct{}
LocalDispatcher should be used when running a non-clustered system
func (LocalDispatcher) Dispatch ¶
func (LocalDispatcher) Dispatch(command Command) error
type UpdateEntityCommand ¶
type UpdateEntityCommand[T models.Entity] struct { Updater EntityUpdater[T] Entity T UpdatedFields boltz.UpdatedFields }
func (*UpdateEntityCommand[T]) Apply ¶
func (self *UpdateEntityCommand[T]) Apply() error
func (*UpdateEntityCommand[T]) Encode ¶
func (self *UpdateEntityCommand[T]) Encode() ([]byte, error)
type Validatable ¶
type Validatable interface {
Validate() error
}
Validatable instances can be validated. Command instances which implement Validable will be validated before Command.Apply is called
