This class is not documented.

Tasks

Reading and Writing

public function read()
public function write($message)

Waiting for Activity

public static function waitForAny($channels, $options) — Wait for any activity on a list of channels. Convenience wrapper around @{method:waitForActivity}.
public static function waitForActivity($reads, $writes, $options) — Wait (using select()) for channels to become ready for reads or writes. This method blocks until some channel is ready to be updated.

Responding to Activity

public function update()

Channel Implementation

public function setName($name) — Set a channel name. This is primarily intended to allow you to debug channel code more easily, by naming channels something meaningful.
public function getName() — Get the channel name, as set by @{method:setName}.

Methods

public function __construct($channel)
Inherited

This method is not documented.

Return

this	//Implicit.//

public function read()
Inherited

PhutilChannel

Read from the channel. A channel defines the format of data that is read from it, so this method may return strings, objects, or anything else.

The default implementation returns bytes.

Return

wild	Data from the channel, normally bytes.

public function write($message)
Inherited

PhutilChannel

Write to the channel. A channel defines what data format it accepts, so this method may take strings, objects, or anything else.

The default implementation accepts bytes.

Parameters

wild

$bytes

Data to write to the channel, normally bytes.

Return

this

public static function waitForAny($channels, $options)
Inherited

PhutilChannel

Wait for any activity on a list of channels. Convenience wrapper around waitForActivity().

Parameters

list<PhutilChannel>	$channels	A list of channels to wait for.
dict	$options	Options, see above.

Return

void

public static function waitForActivity($reads, $writes, $options)
Inherited

PhutilChannel

Wait (using select()) for channels to become ready for reads or writes. This method blocks until some channel is ready to be updated.

It does not provide a way to determine which channels are ready to be updated. The expectation is that you'll just update every channel. This might change eventually.

Available options are:

'read' (list<stream>) Additional streams to select for read.
'write' (list<stream>) Additional streams to select for write.
'except' (list<stream>) Additional streams to select for except.
'timeout' (float) Select timeout, defaults to 1.

NOTE: Extra streams must be streams, not sockets, because this method uses stream_select(), not socket_select().

Parameters

list<PhutilChannel>	$reads	List of channels to wait for reads on.
list<PhutilChannel>	$writes	List of channels to wait for writes on.
array	$options

Return

void

public function update()
Inherited

PhutilChannel

Updates the channel, filling input buffers and flushing output buffers. Returns false if the channel has closed.

Return

bool	True if the channel is still open.

public function setName($name)
Inherited

PhutilChannel

Set a channel name. This is primarily intended to allow you to debug channel code more easily, by naming channels something meaningful.

Parameters

string

$name

Channel name.

Return

this

public function getName()
Inherited

PhutilChannel

Get the channel name, as set by setName().

Return

string

Name of the channel.

public function isOpen()
Inherited

PhutilChannel

Test if the channel is open: active, can be read from and written to, etc.

Return

bool	True if the channel is open.

public function closeWriteChannel()
Inherited

PhutilChannel

Close the channel for writing.

Return

void

public function isOpenForReading()
Inherited

PhutilChannel

Test if the channel is open for reading.

Return

bool	True if the channel is open for reading.

public function isOpenForWriting()
Inherited

PhutilChannel

Test if the channel is open for writing.

Return

bool	True if the channel is open for writing.

protected function readBytes($length)
Inherited

PhutilChannel

Read from the channel's underlying I/O.

Parameters

int

$length

Maximum number of bytes to read.

Return

string

Bytes, if available.

protected function writeBytes($bytes)
Inherited

PhutilChannel

Write to the channel's underlying I/O.

Parameters

string

$bytes

Bytes to write.

Return

int	Number of bytes written.

protected function getReadSockets()
Inherited

PhutilChannel

Get sockets to select for reading.

Return

list<stream>

Read sockets.

protected function getWriteSockets()
Inherited

PhutilChannel

Get sockets to select for writing.

Return

list<stream>

Write sockets.

public function setReadBufferSize($size)
Inherited

PhutilChannel

Set the maximum size of the channel's read buffer. Reads will artificially block once the buffer reaches this size until the in-process buffer is consumed.

Parameters

int|null

$size

Maximum read buffer size, or `null` for a limitless buffer.

Return

this

public function isReadBufferEmpty()
Inherited

PhutilChannel

Test state of the read buffer.

Return

bool	True if the read buffer is empty.

public function isWriteBufferEmpty()
Inherited

PhutilChannel

Test state of the write buffer.

Return

bool	True if the write buffer is empty.

public function getWriteBufferSize()
Inherited

PhutilChannel

Get the number of bytes we're currently waiting to write.

Return

int	Number of waiting bytes.

public function flush()
Inherited

PhutilChannel

Wait for any buffered writes to complete. This is a blocking call. When the call returns, the write buffer will be empty.

Return

wild

protected function didConstruct()
Inherited

This method is not documented.

Return

wild

protected function getUnderlyingChannel()
Inherited

This method is not documented.

Return

wild

private function throwOnRawByteOperations()
Inherited

This method is not documented.

Return

wild

public function didReceiveStderr($channel, $stderr)

This method is not documented.

Parameters

PhutilExecChannel	$channel
	$stderr

Return

wild
