Types

type DomainAccessor

type DomainAccessor interface {
	Entity(key entity.Key) entity.Accessor
	Projection(key string) projection.Accessor
}

type EventHandler

type EventHandler interface {
	Handle(domain DomainAccessor, event interface{}) error
}

func EventHandlerFunc

func EventHandlerFunc(f func(domain DomainAccessor, event interface{}) error) EventHandler

type FieldAlias

type FieldAlias interface {
	GetFieldType() field.Field

	MapValueToAlias(original interface{}) (storage interface{}, err error)
	UnmapValueFromAlias(storage interface{}) (original interface{})
}

type PersistenceCompoundField

type PersistenceCompoundField interface {
	field.Field

	GetSubFieldNames() []string
	GetSubFields() []field.Field

	Type() reflect.Type
	MapCompoundValueToSlice(original interface{}) (storage []interface{}, err error)
	UnmapCompoundValueFromSlice(storage []interface{}) (original interface{})

	AllowedNullElement() bool
}

Fields implementing this interface are handled automatically by persistence, without need to implement own driver

type Schema

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

func NewSchema

func NewSchema() *Schema

func (*Schema) EntityTypes

func (schema *Schema) EntityTypes() map[entity.Key]*entity.Definition

func (*Schema) EventHandler

func (schema *Schema) EventHandler() EventHandler

func (*Schema) ReadModels

func (schema *Schema) ReadModels() map[string]*projection.Definition

func (*Schema) Register

func (schema *Schema) Register(entity *entity.Definition)

func (*Schema) RegisterReadModel

func (schema *Schema) RegisterReadModel(readModel *projection.Definition)

func (*Schema) SetEventHandler

func (schema *Schema) SetEventHandler(handler EventHandler)

type UserCompoundField

type UserCompoundField interface {
	GetSubFieldsStruct() field.StructType
}
