Class ByCallerThrottlingPolicy

java.lang.Object

org.mule.service.scheduler.internal.executor.AbstractByCallerPolicy

org.mule.service.scheduler.internal.executor.ByCallerThrottlingPolicy

public final class ByCallerThrottlingPolicy
extends AbstractByCallerPolicy

Dynamically determines how to handle a task dispatch when its throttling max value has been reached for a ThrottledScheduler.

Each ThrottledScheduler must have its own instance of a ByCallerThrottlingPolicy since it keeps state relative to the owning ThrottledScheduler.

Since:
