Detailed Description

A class for representing forked Workers.

Forked Workers are spawned using a fork()–exec() pattern. This is the default choice for instantiating simulators and is analogous to how SerialMaster launches simulations.

Constructor & Destructor Documentation

◆ ForkedWorkerHandler()

ForkedWorkerHandler::ForkedWorkerHandler	(	const Command &	simulator,
		const std::string &	input_string
	)

Construct from simulator string and input string.

The constructor will fork a process whose standard input and output is redirected to a write and a read pipe, respectively.. The input string is immediately written to the write pipe.

Parameters

simulator	command to run simulation.
input_string	input string to simulator.

Definition at line 15 of file ForkedWorkerHandler.cc.

◆ ~ForkedWorkerHandler()

ForkedWorkerHandler::~ForkedWorkerHandler ( )

overridevirtual

Destructor.

The destructor waits on the forked process and closes the read pipe.

Definition at line 30 of file ForkedWorkerHandler.cc.

Member Function Documentation

◆ isDone()

bool ForkedWorkerHandler::isDone ( )

overridevirtual

Returns: whether Worker has finished.

Poll read pipe for any outstanding output and check whether forked process has finished.

Implements AbstractWorkerHandler.
