class documentation

class ProcessAlias(AliasBase): (source)

An alias which is handled by the execution of a program.

Method	`__init__`	No summary
Method	`__str__`	Build a string representation of this `ProcessAlias` instance.
Method	`createMessageReceiver`	Launch a process and create a message receiver to pass a message to the process.
Method	`spawnProcess`	Spawn a process.
Instance Variable	`path`	The arguments to pass to the process. The first string is the executable's name.
Instance Variable	`program`	The path of the program to be executed.
Instance Variable	`reactor`	A reactor which will be used to create and timeout the child process.

Inherited from AliasBase:

Method	`domain`	Return the domain associated with original address.
Method	`resolve`	Map this alias to its ultimate destination.
Instance Variable	`domains`	See `__init__`.
Instance Variable	`original`	The original address being aliased.

def __init__(self, path, *args): (source) ¶

overrides twisted.mail.alias.AliasBase.__init__

Parameters
path:`bytes`	The command to invoke the program consisting of the path to the executable followed by any arguments.
*args:2-`tuple` of (0) `dict` mapping `bytes` to `IDomain` provider, (1) `bytes`	Arguments for `AliasBase.__init__`.

def __str__(self) -> str: (source) ¶

Build a string representation of this ProcessAlias instance.

Returns
`bytes`	A string containing the command used to invoke the process.

def createMessageReceiver(self): (source) ¶

from twisted.mail.interfaces.IAlias

Launch a process and create a message receiver to pass a message to the process.

Returns
`MessageWrapper`	A message receiver which delivers a message to the process.

def spawnProcess(self, proto, program, path): (source) ¶

Spawn a process.

This wraps the spawnProcess method on reactor so that it can be customized for test purposes.

Parameters
proto:`IProcessProtocol` provider	An object which will be notified of all events related to the created process.
program:`bytes`	The full path name of the file to execute.
path:`list` of `bytes`	The arguments to pass to the process. The first string should be the executable's name.

Returns
`IProcessTransport` provider	A process transport.

The arguments to pass to the process. The first string is the executable's name.

The path of the program to be executed.

reactor: IReactorTime and IReactorProcess provider = (source) ¶

A reactor which will be used to create and timeout the child process.
