Class Summary

Class	Description
AbstractS3AStatisticsSource	Base class for implementing IOStatistics sources in the S3 module.
AwsStatisticsCollector	Collect statistics from the AWS SDK and forward to an instance of StatisticsFromAwsSdk and thence into the S3A statistics.
BondedS3AStatisticsContext	An S3A statistics context which is bonded to a S3AInstrumentation instance -inevitably that of an S3AFileSystem instance.
CountingChangeTracker	A change tracker which increments an atomic long.
EmptyS3AStatisticsContext	Special statistics context, all of whose context operations are no-ops.
EmptyS3AStatisticsContext.EmptyMultipartUploaderStatistics	Multipart Uploader.
ForwardingIOStatisticsStore	This may seem odd having an IOStatisticsStore which does nothing but forward to a wrapped store, but it's designed to assist in subclassing of selective methods, such as those to increment counters, get durations etc.
S3AMultipartUploaderStatisticsImpl	Implementation of the uploader statistics.
StatisticsFromAwsSdkImpl	Hook up AWS SDK Statistics to the S3 counters.
