Types

type MessageHandler

type MessageHandler struct {
	ConfigureFunc   func(c dogma.ProjectionConfigurer)
	HandleEventFunc func(context.Context, *bolt.Tx, dogma.ProjectionEventScope, dogma.Message) error
	TimeoutHintFunc func(m dogma.Message) time.Duration
	CompactFunc     func(context.Context, *bolt.DB, dogma.ProjectionCompactScope) error
}

MessageHandler is a test implementation of boltdb.MessageHandler.

func (*MessageHandler) Compact

func (h *MessageHandler) Compact(ctx context.Context, db *bolt.DB, s dogma.ProjectionCompactScope) error

Compact reduces the size of the projection's data.

If h.CompactFunc is non-nil it returns h.CompactFunc(ctx,db,s), otherwise it returns nil.

func (*MessageHandler) Configure

func (h *MessageHandler) Configure(c dogma.ProjectionConfigurer)

Configure configures the behavior of the engine as it relates to this handler.

c provides access to the various configuration options, such as specifying which types of event messages are routed to this handler.

If h.ConfigureFunc is non-nil, it calls h.ConfigureFunc(c).

func (*MessageHandler) HandleEvent

func (h *MessageHandler) HandleEvent(
	ctx context.Context,
	tx *bolt.Tx,
	s dogma.ProjectionEventScope,
	m dogma.Message,
) error

HandleEvent handles a domain event message that has been routed to this handler.

If h.HandleEventFunc is non-nil it returns h.HandleEventFunc(ctx, tx, s, m).

func (*MessageHandler) TimeoutHint

func (h *MessageHandler) TimeoutHint(m dogma.Message) time.Duration

TimeoutHint returns a duration that is suitable for computing a deadline for the handling of the given message by this handler.

If h.TimeoutHintFunc is non-nil it returns h.TimeoutHintFunc(m), otherwise it returns 0.
