Types

type Blobstore

type Blobstore interface {
	Upload(node *node.Node, source string) error
	Download(node *node.Node) (io.ReadCloser, error)
	Delete(node *node.Node) error
}

Blobstore defines an interface for storing blobs in a blobstore

type PathLookup

type PathLookup interface {
	NodeFromResource(ctx context.Context, ref *provider.Reference) (*node.Node, error)
	NodeFromID(ctx context.Context, id *provider.ResourceId) (n *node.Node, err error)

	InternalRoot() string
	InternalPath(spaceID, nodeID string) string
	Path(ctx context.Context, n *node.Node, hasPermission node.PermissionFunc) (path string, err error)
	MetadataBackend() metadata.Backend
	ReadBlobSizeAttr(ctx context.Context, path string) (int64, error)
	ReadBlobIDAttr(ctx context.Context, path string) (string, error)
	TypeFromPath(ctx context.Context, path string) provider.ResourceType
}

PathLookup defines the interface for the lookup component

type PermissionCheckFunc

type PermissionCheckFunc func(rp *provider.ResourcePermissions) bool

PermissionCheckFunc defined a function used to check resource permissions

type Tree

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

Tree manages a hierarchical tree

New returns a new instance of Tree

func (*Tree) CreateDir

func (t *Tree) CreateDir(ctx context.Context, n *node.Node) (err error)

CreateDir creates a new directory entry in the tree

func (*Tree) Delete

func (t *Tree) Delete(ctx context.Context, n *node.Node) (err error)

Delete deletes a node in the tree by moving it to the trash

func (*Tree) DeleteBlob

func (t *Tree) DeleteBlob(node *node.Node) error

DeleteBlob deletes a blob from the blobstore

func (*Tree) GetMD

func (t *Tree) GetMD(ctx context.Context, n *node.Node) (os.FileInfo, error)

GetMD returns the metadata of a node in the tree
