Detailed Description

Schedules a given command when this command is initialized and ends when it ends, but does not directly run it.

Use this for including a command in a composition without adding its requirements, but only if you know what you are doing. If you are unsure, see the WPILib docs for a complete explanation of proxy semantics. Do not proxy a command from a subsystem already required by the composition, or else the composition will cancel itself when the proxy is reached. If this command is interrupted, it will cancel the command.

Constructor & Destructor Documentation

ProxyCommand() [1/5]

frc2::ProxyCommand::ProxyCommand ( wpi::unique_function< Command *()>  supplier )

explicit

Creates a new ProxyCommand that schedules the supplied command when initialized, and ends when it is no longer scheduled.

Use this for lazily creating proxied commands at runtime. Proxying should only be done to escape from composition requirement semantics, so if only initialization time command construction is needed, use DeferredCommand instead.

Parameters

supplier

the command supplier

See also

DeferredCommand

ProxyCommand() [2/5]

frc2::ProxyCommand::ProxyCommand ( wpi::unique_function< CommandPtr()>  supplier )

explicit

Creates a new ProxyCommand that schedules the supplied command when initialized, and ends when it is no longer scheduled.

Use this for lazily creating proxied commands at runtime. Proxying should only be done to escape from composition requirement semantics, so if only initialization time command construction is needed, use DeferredCommand instead.

Parameters

supplier

the command supplier

See also

DeferredCommand

ProxyCommand() [3/5]

frc2::ProxyCommand::ProxyCommand ( Command *  command )

explicit

Creates a new ProxyCommand that schedules the given command when initialized, and ends when it is no longer scheduled.

Parameters

command

the command to run by proxy

ProxyCommand() [4/5]

frc2::ProxyCommand::ProxyCommand ( std::unique_ptr< Command >  command )

explicit

Creates a new ProxyCommand that schedules the given command when initialized, and ends when it is no longer scheduled.

Note that this constructor passes ownership of the given command to the returned ProxyCommand.

Parameters

command

the command to schedule

ProxyCommand() [5/5]

frc2::ProxyCommand::ProxyCommand ( ProxyCommand &&  other )

default
