Uses of Engine in org.mapdb

Classes in org.mapdb that implement Engine

Modifier and Type	Class and Description
static class	Engine.CloseOnJVMShutdown Closes Engine on JVM shutdown using shutdown hook: Runtime.addShutdownHook(Thread) If engine was closed by user before JVM shutdown, hook is removed to save memory.
static class	Engine.ReadOnly
static class	Engine.ReadOnlyWrapper Wraps an Engine and throws UnsupportedOperationException("Read-only") on any modification attempt.
class	Store
class	StoreAppend append only store
class	StoreArchive Store without index table.
class	StoreCached Extends StoreDirect with Write Cache
class	StoreDirect
static class	StoreDirect.Snapshot
class	StoreHeap Store which keeps all instances on heap.
static class	StoreHeap.Snapshot
class	StoreWAL Write-Ahead-Log
class	TxEngine Naive implementation of Snapshots on top of StorageEngine.
class	TxEngine.Tx
