Functions ¶

func MatcherFunc ¶

func MatcherFunc(object data.Object) expression.MatcherFunc

MatcherFunc is a helper function that uses reflection to look inside a generic data.Object and match it. Because it uses reflection, it should be considered SLOW, and only be used in the mock library.

func New ¶

func New() data.Datastore

New returns a fully initialized Database object

Types ¶

type Collection ¶

type Collection map[string]data.Object

Collection is a mock table

type Datastore ¶

type Datastore map[string]Collection

Datastore is a mock database

func (*Datastore) Close ¶

func (db *Datastore) Close()

Close cleans up any remaining data created by the mock session.

func (*Datastore) Delete ¶

func (db *Datastore) Delete(collection string, object data.Object, comment string) *derp.Error

Delete PERMANENTLY removes a record from the mock database.

func (*Datastore) List ¶

func (db *Datastore) List(collection string, criteria expression.Expression, options ...option.Option) (data.Iterator, *derp.Error)

List retrieves a group of records as an Iterator.

func (*Datastore) Load ¶

func (db *Datastore) Load(collection string, criteria expression.Expression, target data.Object) *derp.Error

Load retrieves a single record from the mock collection.

func (*Datastore) Save ¶

func (db *Datastore) Save(collection string, object data.Object, comment string) *derp.Error

Save adds/inserts a new record into the mock database

func (*Datastore) Session ¶

func (db *Datastore) Session(ctx context.Context) data.Session

Session returns a session that can be used as a mock database.

type Iterator ¶

type Iterator struct {
	Data    []data.Object
	Options []option.Option
	Counter int
}

Iterator represents a generic set of data that can be returned by a datasource.

func NewIterator ¶

func NewIterator(data []data.Object, options ...option.Option) *Iterator

NewIterator generates

func (*Iterator) Close ¶

func (iterator *Iterator) Close() *derp.Error

Close prevents any further records from being read from the iterator

func (*Iterator) Len ¶

func (iterator *Iterator) Len() int

Len returns the number of elements in the collection.

func (*Iterator) Less ¶

func (iterator *Iterator) Less(i int, j int) bool

Less reports whether the element with index i should sort before the element with index j. A return value of TRUE means that the item in position "i" should appear ahead of the item in position "j".

func (*Iterator) Next ¶

func (iterator *Iterator) Next(output data.Object) bool

Next moves the Iterator to the next position in the dataset. If there is another record in the dataset, it returns TRUE, and writes the next record to the "output" variable. If there are no more records, it returns FALSE.

func (*Iterator) Reset ¶

func (iterator *Iterator) Reset()

Reset moves the iterator back to the beginning of the dataaset

func (*Iterator) Swap ¶

func (iterator *Iterator) Swap(i int, j int)

Swpa swpas the elements with indexes i and j
