Interface LogThrottlingHelper.LogAction

Enclosing class:
LogThrottlingHelper
public static interface LogThrottlingHelper.LogAction
An indication of what action the caller should take. If shouldLog() is false, no other action should be taken, and it is an error to try to access any of the summary information. If shouldLog() is true, then the caller should write to its log, and can use the getCount() and getStats(int) methods to determine summary information about what has been recorded into this helper. All summary information in this action only represents LogThrottlingHelper.record(double...) statements which were called after the last time the caller logged something; that is, since the last time a log action was returned with a true value for shouldLog(). Information about the LogThrottlingHelper.record(double...) statement which created this log action is included.
