	WithContext(context.Context) Store

	ReadEntities(string, query.Query, etre.QueryFilter) ([]etre.Entity, error)

	CreateEntities(WriteOp, []etre.Entity) ([]string, error)

	UpdateEntities(WriteOp, query.Query, etre.Entity) ([]etre.Entity, error)

	DeleteEntities(WriteOp, query.Query) ([]etre.Entity, error)

	DeleteLabel(WriteOp, string) (etre.Entity, error)
}

func (ValidationError) Error

type Validator

type Validator interface {
	EntityType(string) error
	Entities([]etre.Entity, byte) error
	WriteOp(WriteOp) error
	DeleteLabel(string) error
}

type WriteOp

type WriteOp struct {
	Caller     string // required (auth.Caller.Name)
	EntityType string // required
	EntityId   string // optional

	// Delete ops do not support set ops like insert and update because no
	// entities are sent by the client on delete. However, the caller can do
	// DELETE /entity/node?setOp=foo&setId=bar&setSize=2 and the controller
	// will pass along the set op values. This could (but not currently) also
	// be used to impose/inject a set op on a write op that doesn't specify
	// a set op.
	SetOp   string // optional
	SetId   string // optional
	SetSize int    // optional
}

WriteOp represents common metadata for insert, update, and delete Store methods.
