Functions

func LoadFileToObject

func LoadFileToObject(path string, object interface{}) error

Load file to struct

func WriteObjectToFile

func WriteObjectToFile(path string, object interface{}) error

Store struct to file

Types

type BlobStore

type BlobStore interface {
	Store(key string, object interface{}) error
	// Ugly way to abstract the return type, as in Go you can't cast []interface{} to a
	// specific type. Users will have to assume the interface{} is a array type of
	// objects created by the factory func.
	// Factory is the function to create a per typed interface object
	LoadAll(factory func() interface{}) (interface{}, error)
	Load(key string, object interface{}) error
	Delete(key string) error
}

func NewBlobStore

func NewBlobStore(name string, config BlobStoreConfig) (BlobStore, error)

type BlobStoreConfig

type BlobStoreConfig interface {
	GetString(name string) string
}

type DatastoreDB

type DatastoreDB struct {
	Name       string
	DomainName string
	ProjectId  string
	Config     BlobStoreConfig
	// contains filtered or unexported fields
}

func NewDatastoreDB

func NewDatastoreDB(name string, config BlobStoreConfig) (*DatastoreDB, error)

func (*DatastoreDB) Delete

func (db *DatastoreDB) Delete(key string) error

func (*DatastoreDB) Load

func (db *DatastoreDB) Load(key string, object interface{}) error

func (*DatastoreDB) LoadAll

func (db *DatastoreDB) LoadAll(f func() interface{}) (interface{}, error)

func (*DatastoreDB) Store

func (db *DatastoreDB) Store(key string, object interface{}) error

type FileStore

type FileStore struct {
	Name string
	Path string
	// contains filtered or unexported fields
}

File store saves each key value as a seperate file in the folder that's specified in the Path This is meant to be used only for local testing and usage.

func (*FileStore) LoadAll

func (file *FileStore) LoadAll(f func() interface{}) (interface{}, error)

func (*FileStore) Store

func (file *FileStore) Store(key string, object interface{}) error

type SimpleDB

type SimpleDB struct {
	Name string

	Region string
	Config BlobStoreConfig
	// contains filtered or unexported fields
}

func NewSimpleDB

func NewSimpleDB(name string, config BlobStoreConfig) (*SimpleDB, error)

func (*SimpleDB) Delete

func (db *SimpleDB) Delete(key string) error

func (*SimpleDB) Load

func (db *SimpleDB) Load(key string, object interface{}) error

func (*SimpleDB) LoadAll
