Classes
struct	foedus::storage::VolatilePagePointer
	Represents a pointer to a volatile page with modification count for preventing ABA. More...
struct	foedus::storage::DualPagePointer
	Represents a pointer to another page (usually a child page). More...

Namespaces
	foedus
	Root package of FOEDUS (Fast Optimistic Engine for Data Unification Services).
	foedus::storage
	Storage Manager, which implements a couple of key/value stores.

Typedefs
typedef uint32_t	foedus::storage::StorageId
	Unique ID for storage. More...
typedef assorted::FixedString< 60 >	foedus::storage::StorageName
	Represents a unique name of a storage. More...
typedef thread::ThreadGroupId	foedus::storage::PartitionId
	As partition=NUMA node, this is just a synonym of foedus::thread::ThreadGroupId. More...
typedef uint64_t	foedus::storage::SnapshotPagePointer
	Page ID of a snapshot page. More...
typedef uint64_t	foedus::storage::SnapshotLocalPageId
	Represents a local page ID in each one snapshot file in some NUMA node. More...
typedef uint32_t	foedus::storage::Checksum
	Checksum of a snapshot page. More...

Enumerations
enum	foedus::storage::StorageType {   foedus::storage::kInvalidStorage = 0, foedus::storage::kArrayStorage, foedus::storage::kHashStorage, foedus::storage::kMasstreeStorage,   foedus::storage::kSequentialStorage }
	Type of the storage, such as hash. More...
enum	foedus::storage::StorageStatus { foedus::storage::kNotExists = 0, foedus::storage::kExists, foedus::storage::kMarkedForDeath }
	Status of a storage. More...
