Member Function Documentation

void Scheduler::AddCommand

(

Command *

command

)

Add a command to be scheduled later. In any pass through the scheduler, all commands are added to the additions list, then at the end of the pass, they are all scheduled.

Parameters

command

The command to be scheduled

Definition at line 64 of file Scheduler.cpp.

Scheduler * Scheduler::GetInstance ( )

static

Returns the Scheduler, creating it if one does not exist.

Returns

the Scheduler

Definition at line 47 of file Scheduler.cpp.

void Scheduler::RegisterSubsystem

(

Subsystem *

subsystem

)

Registers a Subsystem to this Scheduler, so that the Scheduler might know if a default Command needs to be run. All Subsystems should call this.

Parameters

system

the system

Definition at line 208 of file Scheduler.cpp.

void Scheduler::Remove

(

Command *

command

)

Removes the Command from the Scheduler.

Parameters

command

the command to remove

Definition at line 222 of file Scheduler.cpp.

void Scheduler::Run

(

)

Runs a single iteration of the loop. This method should be called often in order to have a functioning Command system. The loop has five stages:

1. Poll the Buttons
2. Execute/Remove the Commands
3. Send values to SmartDashboard
4. Add Commands
5. Add Defaults
