Functions

func ToKey

func ToKey(in interface{}) string

ToKey transforms a struct into a hash key for this repository

Types

type HashKeyValueRepo

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

HashKeyValueRepo extends functionalities of KeyValueStore. Implementations are based on methods provided in the inner repository. The performance is not optimal since it is not based upon a native persistence layer, but instead on an additional layer of abstraction.

func NewHashKeyValueRepo

func NewHashKeyValueRepo(repo KeyValueRepo) *HashKeyValueRepo

NewHashKeyValueRepo creates a new instance and uses an initialized KeyValueRepo

func (*HashKeyValueRepo) Contains

func (repo *HashKeyValueRepo) Contains(key string) bool

Contains checks if a given key is in the repository

func (*HashKeyValueRepo) ContainsValue

func (repo *HashKeyValueRepo) ContainsValue(in interface{}) bool

ContainsValue checks if a value is in the repository

func (*HashKeyValueRepo) Count

func (repo *HashKeyValueRepo) Count() (int, error)

Count calls FindAll() and calculates the length

func (*HashKeyValueRepo) Delete

func (repo *HashKeyValueRepo) Delete(key string) error

Delete calls function of wrapped repository

func (*HashKeyValueRepo) Find

func (repo *HashKeyValueRepo) Find(key string) (KeyValuePair, error)

Find calls function of wrapped repository

func (*HashKeyValueRepo) FindAll

func (repo *HashKeyValueRepo) FindAll() ([]KeyValuePair, error)

FindAll calls function of wrapped repository

func (*HashKeyValueRepo) Overwrite

func (repo *HashKeyValueRepo) Overwrite(in interface{}) (KeyValuePair, error)

Overwrite calls function of wrapped repository

func (*HashKeyValueRepo) Save

func (repo *HashKeyValueRepo) Save(in interface{}) (KeyValuePair, error)

Save calls function of wrapped repository

type InMemoryRepo

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

InMemoryRepo stores all entities in-memory

func NewInMemoryRepo

func NewInMemoryRepo() *InMemoryRepo

NewInMemoryRepo creates a new instance of the repository

func (*InMemoryRepo) Delete

func (repo *InMemoryRepo) Delete(key string) error

Delete an item from the repository

func (*InMemoryRepo) Find

func (repo *InMemoryRepo) Find(key string) (KeyValuePair, error)

Find retrieves and item from the repository

func (*InMemoryRepo) FindAll

func (repo *InMemoryRepo) FindAll() ([]KeyValuePair, error)

FindAll items

func (*InMemoryRepo) Overwrite

func (repo *InMemoryRepo) Overwrite(key string, in interface{}) (KeyValuePair, error)

func (*InMemoryRepo) Save

func (repo *InMemoryRepo) Save(key string, in interface{}) (KeyValuePair, error)

Save one item

type KeyValuePair

type KeyValuePair struct {
	Key   string      `json:"key"`
	Value interface{} `json:"value"`
}

KeyValuePair has the stored entity in addition to an autogenerated id

func (KeyValuePair) ToStruct

func (item KeyValuePair) ToStruct(jsonString string) (interface{}, error)

ToStruct converts json string to struct

type KeyValueRepo

type KeyValueRepo interface {
	FindAll() ([]KeyValuePair, error)
	// saves an item, if the key of the item already exists an error is returned
	Save(key string, in interface{}) (KeyValuePair, error)
	// saves an item, if the key of the item already exists it is overwritten
	Overwrite(key string, in interface{}) (KeyValuePair, error)
	Delete(key string) error
	Find(key string) (KeyValuePair, error)
}

KeyValueRepo is a generic repository which accepts values of type interface
