Detailed Description

A command that runs another command in perpetuity, ignoring that command's end conditions. While this class does not extend CommandGroupBase, it is still considered a CommandGroup, as it allows one to compose another command within it; the command instances that are passed to it cannot be added to any other groups, or scheduled individually.

As a rule, CommandGroups require the union of the requirements of their component commands.

Constructor & Destructor Documentation

◆ PerpetualCommand()

edu.wpi.first.wpilibj2.command.PerpetualCommand.PerpetualCommand ( Command  command)

Creates a new PerpetualCommand. Will run another command in perpetuity, ignoring that command's end conditions, unless this command itself is interrupted.

Parameters
commandthe command to run perpetually

Member Function Documentation

◆ end()

void edu.wpi.first.wpilibj2.command.PerpetualCommand.end ( boolean  interrupted)

The action to take when the command ends. Called when either the command finishes normally, or when it interrupted/canceled.

Do not schedule commands here that share requirements with this command. Use andThen(Command...) instead.

Parameters
interruptedwhether the command was interrupted/canceled

Implements edu.wpi.first.wpilibj2.command.Command.

◆ execute()

void edu.wpi.first.wpilibj2.command.PerpetualCommand.execute ( )

The main body of a command. Called repeatedly while the command is scheduled.

Implements edu.wpi.first.wpilibj2.command.Command.

◆ initialize()

void edu.wpi.first.wpilibj2.command.PerpetualCommand.initialize ( )

The initial subroutine of a command. Called once when the command is initially scheduled.

Implements edu.wpi.first.wpilibj2.command.Command.

◆ runsWhenDisabled()

boolean edu.wpi.first.wpilibj2.command.PerpetualCommand.runsWhenDisabled ( )

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

Implements edu.wpi.first.wpilibj2.command.Command.
