func (*FileEvent) IsCreate

func (e *FileEvent) IsCreate() bool

IsCreate reports whether the FileEvent was triggered by a creation

func (*FileEvent) IsDelete

func (e *FileEvent) IsDelete() bool

IsDelete reports whether the FileEvent was triggered by a delete

func (*FileEvent) IsModify

func (e *FileEvent) IsModify() bool

IsModify reports whether the FileEvent was triggered by a file modification or attribute change

func (*FileEvent) IsRename

func (e *FileEvent) IsRename() bool

IsRename reports whether the FileEvent was triggered by a change name

func (*FileEvent) String

func (e *FileEvent) String() string

String formats the event e in the form "filename: DELETE|MODIFY|..."

type Watcher

type Watcher struct {
	Event chan *FileEvent // Events are returned on this channel
	Error chan error      // Errors are sent on this channel

func NewWatcher

func NewWatcher() (*Watcher, error)

NewWatcher creates and returns a Watcher.

func (*Watcher) AddWatch

func (w *Watcher) AddWatch(path string, flags uint32) error

Remove a watch on a file

func (*Watcher) Watch

func (w *Watcher) Watch(path string) error
