Method Details

from

public BUILDER from(FixedRateConfig prototype)

Update this builder from an existing prototype instance. This method disables automatic service discovery.

Parameters:

prototype - existing prototype to update this builder from

Returns:

updated builder instance

from

public BUILDER from(FixedRateConfig.BuilderBase<?,?> builder)

Update this builder from an existing prototype builder instance.

Parameters:

builder - existing builder prototype to update this builder from

Returns:

updated builder instance

config

public BUILDER config(Config config)

Update builder from configuration (node of this type). If a value is present in configuration, it would override currently configured values.

Specified by:

config in interface Prototype.ConfiguredBuilder<BUILDER extends FixedRateConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends FixedRateConfig>

Overrides:

config in class TaskConfig.BuilderBase<BUILDER extends FixedRateConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends FixedRateConfig>

Parameters:

config - configuration instance used to obtain values to update this builder

Returns:

updated builder instance

initialDelay

public BUILDER initialDelay(long initialDelay)

Initial delay of the first invocation. Time unit is by default TimeUnit.SECONDS, can be specified with timeUnit().

Parameters:

initialDelay - initial delay value

Returns:

updated builder instance

See Also:

• initialDelay()

delay

public BUILDER delay(long delay)

Fixed rate delay between each invocation. Time unit is by default TimeUnit.SECONDS, can be specified with timeUnit(java.util.concurrent.TimeUnit).

Parameters:

delay - delay between each invocation

Returns:

updated builder instance

See Also:

• delay()

delayType

public BUILDER delayType(FixedRate.DelayType delayType)

Configure whether the delay between the invocations should be calculated from the time when previous task started or ended. Delay type is by default FixedRate.DelayType.SINCE_PREVIOUS_START.

Parameters:

delayType - delay type

Returns:

updated builder instance

See Also:

• delayType()

task

public BUILDER task(ScheduledConsumer<FixedRateInvocation> task)

Task to be scheduled for execution.

Parameters:

task - scheduled for execution

Returns:

updated builder instance

See Also:

• task()

timeUnit

public BUILDER timeUnit(TimeUnit timeUnit)

TimeUnit used for interpretation of values provided with delay(long) and initialDelay(long).

Parameters:

timeUnit - time unit for interpreting values in delay(long) and initialDelay(long)

Returns:

updated builder instance

See Also:

• timeUnit()

initialDelay

public long initialDelay()

Initial delay of the first invocation. Time unit is by default TimeUnit.SECONDS, can be specified with timeUnit().

Returns:

the initial delay

delay

public Optional<Long> delay()

Fixed rate delay between each invocation. Time unit is by default TimeUnit.SECONDS, can be specified with timeUnit(java.util.concurrent.TimeUnit).

Returns:

the delay

delayType

public FixedRate.DelayType delayType()

Configure whether the delay between the invocations should be calculated from the time when previous task started or ended. Delay type is by default FixedRate.DelayType.SINCE_PREVIOUS_START.

Returns:

the delay type

task

public Optional<ScheduledConsumer<FixedRateInvocation>> task()

Task to be scheduled for execution.

Returns:

the task

timeUnit

Returns:

the time unit

config

public Optional<Config> config()

If this instance was configured, this would be the config instance used.

Overrides:

config in class TaskConfig.BuilderBase<BUILDER extends FixedRateConfig.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends FixedRateConfig>

Returns:

config node used to configure this builder, or empty if not configured
