}
func NewLayeredMap ¶
func NewLayeredMap(h func(string) (string, error)) *LayeredMap
NewLayeredMap creates a new layered map which keeps track of adds and deletes.

Add will add the specified file s to the current layer.
func (*LayeredMap) AddDelete ¶
func (l *LayeredMap) AddDelete(s string) error
AddDelete will delete the specific files in the current layer.
func (*LayeredMap) CheckFileChange ¶
func (l *LayeredMap) CheckFileChange(s string) (bool, error)
CheckFileChange checks whether a given file (needs to exist) changed from the current layered map by its hashing function. If the file does not exist, an error is returned. Returns true if the file is changed.
func (*LayeredMap) GetCurrentPaths ¶
func (l *LayeredMap) GetCurrentPaths() map[string]struct{}
GetCurrentPaths returns all existing paths in the actual current image cached by FlattenLayers.
func (*LayeredMap) Key ¶
func (l *LayeredMap) Key() (string, error)
Key returns a hash for added and delted files.
type Snapshotter ¶
type Snapshotter struct {
// contains filtered or unexported fields
}
Snapshotter holds the root directory from which to take snapshots, and a list of snapshots taken
