Bool Kernel::UserProcessScheduler::IsKernel ( )

overridevirtual

Is it a kernel scheduler?

Reimplemented from Kernel::ISchedulable.

IsUser()

Bool Kernel::UserProcessScheduler::IsUser ( )

overridevirtual

Reimplemented from Kernel::ISchedulable.

operator bool()

Kernel::UserProcessScheduler::operator bool

(

)

this checks if any process is on the team.

operator!()

Bool Kernel::UserProcessScheduler::operator!

(

)

this checks if no process is on the team.

Remove()

Void Kernel::UserProcessScheduler::Remove

(

ProcessID

process_id

)

Remove process from the team.

Parameters

process_id

process slot inside team.

Return values

true	process was removed.
false	process doesn't exist in team.

Run()

SizeT Kernel::UserProcessScheduler::Run ( )

noexcept

Run User scheduler object.

Returns

USER_PROCESS count executed within a team.

we store this guy to tell the scheduler how many things we have scheduled.

Check if the process needs to be run.

Increase the usage time of the process.

Spawn()

ProcessID Kernel::UserProcessScheduler::Spawn	(	const Char *	name,
		VoidPtr	code,
		VoidPtr	image )

Add process to team.

Parameters

process

the process Ref class.

Returns

the process index inside the team.

Todo

File Tree allocation and dispose methods (amlal)

SwitchTeam()

BOOL Kernel::UserProcessScheduler::SwitchTeam

(

UserProcessTeam &

team

)

Switches the current team.

Parameters

team	the new team to switch to.

Return values

true	team was switched.
false	team was not switched.

The()

UserProcessScheduler & Kernel::UserProcessScheduler::The

(

)

Retrieves the singleton of the process scheduler.

TheCurrentProcess()

Ref< USER_PROCESS > & Kernel::UserProcessScheduler::TheCurrentProcess

(

)

Gets current running process.

Returns

TheCurrentTeam()

UserProcessTeam & Kernel::UserProcessScheduler::TheCurrentTeam

(

)
