Method Details

addRequirements

public final void addRequirements(Subsystem... requirements)

Adds the specified requirements to the command.

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
