Types

type In

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

In is an input stream used by the DockerCli to read user input

func NewIn

func NewIn(in io.ReadCloser) *In

NewIn returns a new In object from a ReadCloser

func (*In) CheckTty

func (i *In) CheckTty(attachStdin, ttyMode bool) error

CheckTty checks if we are trying to attach to a container tty from a non-tty client input stream, and if so, returns an error.

func (*In) Close

func (i *In) Close() error

Close implements the Closer interface

func (*In) FD

func (s *In) FD() uintptr

FD returns the file descriptor number for this stream

func (*In) IsTerminal

func (s *In) IsTerminal() bool

IsTerminal returns true if this stream is connected to a terminal

func (*In) Read

func (i *In) Read(p []byte) (int, error)

func (*In) SetRawTerminal

func (i *In) SetRawTerminal() (err error)

SetRawTerminal sets raw mode on the input terminal

type Out

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

Out is an output stream used by the DockerCli to write normal program output.

func NewOut

func NewOut(out io.Writer) *Out

NewOut returns a new Out object from a Writer

func (*Out) FD

func (s *Out) FD() uintptr

FD returns the file descriptor number for this stream

func (*Out) GetTtySize

func (o *Out) GetTtySize() (uint, uint)

GetTtySize returns the height and width in characters of the tty

func (*Out) IsTerminal

func (s *Out) IsTerminal() bool

IsTerminal returns true if this stream is connected to a terminal

func (*Out) SetRawTerminal

func (o *Out) SetRawTerminal() (err error)

SetRawTerminal sets raw mode on the input terminal

func (*Out) Write

func (o *Out) Write(p []byte) (int, error)

type Streams

type Streams interface {
	In() *In
	Out() *Out
	Err() io.Writer
}

Streams is an interface which exposes the standard input and output streams
