Types

type Stores

type Stores interface {
	// Metadata yields the metadata storage for a context
	Metadata() storage.Store
	// SetMetadata sets the context storage for metadata, other than versioning metadata
	SetMetadata(metadata storage.Store)

	// ReadLog yields the Read Log storage for a context
	ReadLog() storage.Store
	// SetReadLog sets the context storage for Read Log
	SetReadLog(readLog storage.Store)

	// VMetadata yields the version metadata storage for a context
	VMetadata() storage.Store
	// SetVMetadata sets the context storage for versioning metadata
	SetVMetadata(vMetadata storage.Store)

	// Blob yields the Blob storage for a context
	Blob() storage.Store
	// SetBlob sets the context storage for blobs
	SetBlob(blob storage.Store)

	// Wal yields the Write Ahead Log storage for a context
	Wal() storage.Store
	// SetWal sets the context storage for Write Ahead Log
	SetWal(wal storage.Store)
}

Stores defines a complete context for datamon objects
