Detailed Description

Runs one of a selection of commands, either using a selector and a key to command mapping, or a supplier that returns the command directly at runtime. Does not actually schedule the selected command - rather, the command is run through this command; this ensures that the command will behave as expected if used as part of a CommandGroup. Requires the requirements of all included commands, again to ensure proper functioning when used in a CommandGroup. If this is undesired, consider using ScheduleCommand.

As this command contains multiple component commands within it, it is technically a command group; 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

◆ SelectCommand() [1/2]

edu.wpi.first.wpilibj2.command.SelectCommand.SelectCommand ( Map< Object, Command commands,
Supplier< Object >  selector 

Creates a new selectcommand.

selectorthe selector to determine which command to run

◆ SelectCommand() [2/2]

edu.wpi.first.wpilibj2.command.SelectCommand.SelectCommand ( Supplier< Command toRun)

Creates a new selectcommand.

toRuna supplier providing the command to run

Member Function Documentation

◆ end()

void edu.wpi.first.wpilibj2.command.SelectCommand.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.

interruptedwhether the command was interrupted/canceled

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

◆ execute()

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

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

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

◆ isFinished()

boolean edu.wpi.first.wpilibj2.command.SelectCommand.isFinished ( )

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

whether the command has finished.

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

◆ runsWhenDisabled()

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

Whether the given command should run when the robot is disabled. Override to return true if the command should run when disabled.

whether the command should run when the robot is disabled

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