Interface Summary

Interface	Description
BatchHelper.QueueRequestCallback	Callback that causes a single StorageRequest to be added to the BatchRequest.
GoogleCloudStorage	Interface for exposing the Google Cloud Storage API behavior in a way more amenable to writing filesystem semantics on top of it, without having to deal with API-specific considerations such as HttpTransports, credentials, network errors, batching, etc.
GoogleCloudStorageImpl.BackOffFactory	A factory for producing BackOff objects.
GoogleCloudStorageItemInfo.Provider	Convenience interface for classes which want to implement Provider of GoogleCloudStorageItemInfo for callers which may not know the concrete type of an object, but want to check if the object happens to be an instance of this InfoProvider.
PathCodec	Methods for converting between GCS buckets and objects and URIs that GoogleCloudStorageFileSystem can use to reference objects.

Class Summary

Class	Description
BatchHelper	BatchHelper abstracts out the logic for maximum requests per batch, and also allows a workaround for the fact that BatchRequest was made a "final class" for some reason, making it impossible to unittest.
BatchHelper.Factory	Since each BatchHelper instance should be tied to a particular related set of requests, use cases will generally interact via an injectable BatchHelper.Factory.
CreateBucketOptions	Options that can be specified when creating a bucket in the GoogleCloudStorage.
CreateFileOptions	Options that can be specified when creating a file in the GoogleCloudFileSystem.
CreateObjectOptions	Options for creating objects in GCS.
FileInfo	Contains information about a file or a directory.
ForwardingGoogleCloudStorage	A class that wraps a GoogleCloudStorage object, delegating all calls to it.
GoogleCloudStorage.ListPage<T>	Paged list request response
GoogleCloudStorageExceptions	Miscellaneous helper methods for standardizing the types of exceptions thrown by the various GCS-based FileSystems.
GoogleCloudStorageFileSystem	Provides a POSIX like file system layered on top of Google Cloud Storage (GCS).
GoogleCloudStorageFileSystemOptions	Configurable options for the GoogleCloudStorageFileSystem class.
GoogleCloudStorageFileSystemOptions.Builder	Mutable builder for GoogleCloudStorageFileSystemOptions.
GoogleCloudStorageImpl	Provides read/write access to Google Cloud Storage (GCS), using Java nio channel semantics.
GoogleCloudStorageItemInfo	Contains information about an item in Google Cloud Storage.
GoogleCloudStorageOptions	Configuration options for the GoogleCloudStorage class.
GoogleCloudStorageOptions.Builder	Mutable builder for the GoogleCloudStorageOptions class.
GoogleCloudStorageReadChannel	Provides seekable read access to GCS.
GoogleCloudStorageReadOptions	Advanced options for reading GoogleCloudStorage objects.
GoogleCloudStorageReadOptions.Builder	Mutable builder for GoogleCloudStorageReadOptions.
GoogleCloudStorageStrings	Contains helper methods for standardizing String-matching algorithms specific to GCS.
GoogleCloudStorageWriteChannel	Implements WritableByteChannel to provide write access to GCS.
ObjectWriteConditions	Conditions on which a object write should be allowed to continue.
PerformanceCachingGoogleCloudStorage	This class adds a caching layer around a GoogleCloudStorage instance, caching calls that create, update, remove, and query for GoogleCloudStorageItemInfo.
PerformanceCachingGoogleCloudStorageOptions	Configurable options for PerformanceCachingGoogleCloudStorage.
PerformanceCachingGoogleCloudStorageOptions.Builder	Builder class for PerformanceCachingGoogleCloudStorageOptions.
PrefixMappedItemCache	A semi-persistent storage for GoogleCloudStorageItemInfo that maintains indexes based on the item's bucket and object name.
PrefixMappedItemCache.Config	Container for various cache-configuration parameters used by a PrefixMappedItemCache when managing expiration/retention policies, etc.
StorageResourceId	Data struct representing either a GCS StorageObject, a GCS Bucket or the GCS root (gs://).
ThrottledGoogleCloudStorage	Throttled GCS implementation that will limit our bucket creation and delete operations to N per second.
UpdatableItemInfo	Item information that can be updated without re-writing an entire object.
VerificationAttributes	GCS provided validation attributes for a single object.

Enum Summary

Enum	Description
GoogleCloudStorageReadOptions.Fadvise	Operational modes of fadvise feature.
GoogleCloudStorageReadOptions.GenerationReadConsistency	Options of read consistency on generations.
ThrottledGoogleCloudStorage.StorageOperation	Operations that may be throttled.
