Method Details

addRequirements

public final void addRequirements(Subsystem... requirements)

Adds the specified subsystems to the requirements of the command. The scheduler will prevent two commands that require the same subsystem from being scheduled simultaneously.

Note that the scheduler determines the requirements of a command when it is scheduled, so this method should normally be called from the command's constructor.

Parameters:

requirements - the requirements to add

getRequirements

public Set<Subsystem> getRequirements()

Description copied from interface: Command

Specifies the set of subsystems used by this command. Two commands cannot use the same subsystem at the same time. If another command is scheduled that shares a requirement, Command.getInterruptionBehavior() will be checked and followed. If no subsystems are required, return an empty set.

Note: it is recommended that user implementations contain the requirements as a field, and return that field here, rather than allocating a new set every time this is called.

Specified by:

getRequirements in interface Command

Returns:

the set of subsystems that are required

Command.InterruptionBehavior

getName

public String getName()

Description copied from interface: Command

Gets the name of this Command. Defaults to the simple class name if not overridden.

Specified by:

getName in interface Command

Returns:

The display name of the Command

setName

public void setName(String name)

Sets the name of this Command.

Specified by:

setName in interface Command

Parameters:

name - name

getSubsystem

public String getSubsystem()

Gets the subsystem name of this Command.

Returns:

Subsystem name

setSubsystem

public void setSubsystem(String subsystem)

Sets the subsystem name of this Command.

Parameters:

subsystem - subsystem name

initSendable

public void initSendable(SendableBuilder builder)

Initializes this sendable. Useful for allowing implementations to easily extend SendableBase.

Specified by:

initSendable in interface Sendable

Parameters:

builder - the builder used to construct this sendable
