Method Details

fixedRate

public static PollerSpec fixedRate(long period)

Create a PollerSpec based on the provided fixed rate period. The "fixed rate" means that periodic interval should be measured between the scheduled start times rather than between actual completion times.

Parameters:

period - the fixed rate period (in milliseconds) to use.

Returns:

the PollerSpec

See Also:

• PeriodicTrigger

fixedRate

public static PollerSpec fixedRate(Duration period)

Create a PollerSpec based on the provided fixed rate period. The "fixed rate" means that periodic interval should be measured between the scheduled start times rather than between actual completion times.

Parameters:

period - the fixed rate period to use.

Returns:

the PollerSpec

See Also:

• PeriodicTrigger

fixedRate

public static PollerSpec fixedRate(Duration period,
 Duration initialDelay)

Create a PollerSpec based on the provided fixed rate period and initial delay. The "fixed rate" means that periodic interval should be measured between the scheduled start times rather than between actual completion times.

Parameters:

period - the fixed rate period to use.

initialDelay - the initial delay to use.

Returns:

the PollerSpec

See Also:

• PeriodicTrigger

fixedRate

public static PollerSpec fixedRate(long period,
 long initialDelay)

Create a PollerSpec based on the provided fixed rate period and initial delay. The "fixed rate" means that periodic interval should be measured between the scheduled start times rather than between actual completion times.
