Interface IdleStrategy

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IdleStrategy

Handler to define strategy in idle loops when no work is performed. Some applications may want to busy spin in a loop, others prefer to back off and release the CPU core to perform more useful work.

Field Summary

Fields

Modifier and Type	Field and Description
static IdleStrategy	NO_OP Idle strategy that performs a no-OP, that is, an idle loop will essentially become a busy-spin loop.

Method Summary

Modifier and Type	Method and Description
void	idle() Invoked if no work was done
default void	idle(boolean workDone) Invoked with boolean flag indicating whether work was done or not.
default void	reset() Invoked if some work was performed and an idle strategy should reset to prepare for the next idle phase

Field Detail

NO_OP

static final IdleStrategy NO_OP

Idle strategy that performs a no-OP, that is, an idle loop will essentially become a busy-spin loop.

Method Detail

idle

void idle()

Invoked if no work was done

idle

default void idle(boolean workDone)

Invoked with boolean flag indicating whether work was done or not. Delegates to reset() when work was done and to idle() if not.

Parameters:

workDone - true if some work was performed

reset

default void reset()

Invoked if some work was performed and an idle strategy should reset to prepare for the next idle phase
