Detailed Description

A command composition that runs a set of commands in parallel, ending only when a specific command (the "deadline") ends, interrupting all other commands that are still running at that point.

The rules for command compositions apply: command instances that are passed to it are owned by the composition and cannot be added to any other composition or scheduled individually, and the composition requires all subsystems its components require.

This class is provided by the NewCommands VendorDep

Constructor & Destructor Documentation

◆ ParallelDeadlineGroup() [1/5]

frc2::ParallelDeadlineGroup::ParallelDeadlineGroup	(	std::unique_ptr< Command > &&	deadline,
		std::vector< std::unique_ptr< Command > > &&	commands
	)

Creates a new ParallelDeadlineGroup.

The given commands (including the deadline) will be executed simultaneously. The composition will finish when the deadline finishes, interrupting all other still-running commands. If the composition is interrupted, only the commands still running will be interrupted.

Parameters

deadline	the command that determines when the composition ends
commands	the commands to be executed

template<class T , class... Types, typename = std::enable_if_t< std::is_base_of_v<Command, std::remove_reference_t<T>>>, typename = std::enable_if_t<std::conjunction_v< std::is_base_of<Command, std::remove_reference_t<Types>>...>>>

frc2::ParallelDeadlineGroup::ParallelDeadlineGroup	(	T &&	deadline,
		Types &&...	commands
	)

Creates a new ParallelDeadlineGroup.

The given commands (including the deadline) will be executed simultaneously. The composition will finish when the deadline finishes, interrupting all other still-running commands. If the composition is interrupted, only the commands still running will be interrupted.

Parameters

deadline	the command that determines when the composition ends
commands	the commands to be executed

void frc2::ParallelDeadlineGroup::AddCommands ( Types &&... commands )

inline

◆ End()

void frc2::ParallelDeadlineGroup::End ( bool interrupted )

finalvirtual

The action to take when the command ends.

Called when either the command finishes normally, or when it interrupted/canceled.

Parameters

interrupted whether the command was interrupted/canceled

Reimplemented from frc2::Command.

◆ Execute()

void frc2::ParallelDeadlineGroup::Execute ( )

finalvirtual

The main body of a command.

Called repeatedly while the command is scheduled.

Reimplemented from frc2::Command.

◆ GetInterruptionBehavior()

Command::InterruptionBehavior frc2::ParallelDeadlineGroup::GetInterruptionBehavior ( ) const

overridevirtual

How the command behaves when another command with a shared requirement is scheduled.

Returns: a variant of InterruptionBehavior, defaulting to kCancelSelf.

Reimplemented from frc2::Command.

◆ Initialize()

void frc2::ParallelDeadlineGroup::Initialize ( )

finalvirtual

The initial subroutine of a command.

Called once when the command is initially scheduled.

Reimplemented from frc2::Command.

◆ InitSendable()

void frc2::ParallelDeadlineGroup::InitSendable ( wpi::SendableBuilder & builder )

overridevirtual

Initializes this Sendable object.

Parameters

builder sendable builder

Reimplemented from frc2::CommandBase.

◆ IsFinished()

bool frc2::ParallelDeadlineGroup::IsFinished ( )

finalvirtual

Whether the command has finished.

Once a command finishes, the scheduler will call its end() method and un-schedule it.

Returns: whether the command has finished.

Reimplemented from frc2::Command.

◆ RunsWhenDisabled()

bool frc2::ParallelDeadlineGroup::RunsWhenDisabled ( ) const

overridevirtual

Whether the given command should run when the robot is disabled.

Override to return true if the command should run when disabled.

Returns: whether the command should run when the robot is disabled

Reimplemented from frc2::Command.
