Interface Summary

Interface	Description
ContextAccessors	An interface to implement for providing accessors to S3AFileSystem-level API calls.
OperationCallbacks	These are all the callbacks which the RenameOperation and DeleteOperation operations need, derived from the appropriate S3AFileSystem methods.

Class Summary

Class	Description
AbstractStoreOperation	Base class of operations in the store.
BulkDeleteRetryHandler	Handler for bulk delete retry events.
CallableSupplier<T>	A bridge from Callable to Supplier; catching exceptions raised by the callable and wrapping them as appropriate.
ChangeDetectionPolicy	Object change detection policy.
ChangeTracker	Change tracking for input streams: the version ID or etag of the object is tracked and compared on open/re-open.
CopyOutcome	Extracts the outcome of a TransferManager-executed copy operation.
DeleteOperation	Implementation of the delete() operation.
ErrorTranslation	Translate from AWS SDK-wrapped exceptions into IOExceptions with as much information as possible.
ErrorTranslation.AwsErrorCodes	AWS error codes explicitly recognized and processes specially; kept in their own class for isolation.
ExecutingStoreOperation<T>	A subclass of AbstractStoreOperation which provides a method ExecutingStoreOperation.execute() that may be invoked exactly once.
InternalConstants	Internal constants private only to the S3A codebase.
LogExactlyOnce	Log exactly once, even across threads.
MultiObjectDeleteSupport	Support for Multi Object Deletion.
NetworkBinding	Configures network settings when communicating with AWS services.
RenameOperation	A parallelized rename operation which updates the metastore in the process, through whichever RenameTracker the store provides.
StoreContext	This class provides the core context of the S3A filesystem to subsidiary components, without exposing the entire parent class.

Enum Summary

Enum	Description
ChangeDetectionPolicy.Mode	What to do when change is detected.
ChangeDetectionPolicy.Source	The S3 object attribute used to detect change.
StatusProbeEnum	Enum of probes which can be made of S3.
