All Implemented Interfaces:

TriggeringPolicy<E>, ContextAware, LifeCycle

public class SizeBasedTriggeringPolicy<E>
extends TriggeringPolicyBase<E>

SizeBasedTriggeringPolicy looks at size of the file being currently written to. If it grows bigger than the specified size, the FileAppender using the SizeBasedTriggeringPolicy rolls the file and creates a new one. For more information about this policy, please refer to the online manual at http://logback.qos.ch/manual/appenders.html#SizeBasedTriggeringPolicy
