Detailed Description

Defers Command construction to runtime.

Runs the command returned by a supplier when this command is initialized, and ends when it ends. Useful for performing runtime tasks before creating a new command. If this command is interrupted, it will cancel the command.

Note that the supplier must create a new Command each call. For selecting one of a preallocated set of commands, use SelectCommand.

Constructor & Destructor Documentation

DeferredCommand() [1/2]

frc2::DeferredCommand::DeferredCommand	(	wpi::unique_function< CommandPtr()>	supplier,
		Requirements	requirements )

Creates a new DeferredCommand that directly runs the supplied command when initialized, and ends when it ends.

Useful for lazily creating commands when the DeferredCommand is initialized, such as if the supplied command depends on runtime state. The supplier will be called each time this command is initialized. The supplier must create a new Command each call.

Parameters

supplier	The command supplier
requirements	The command requirements.
