Package com.bigdata.rwstore

Interface Summary

Allocator
IAllocationContext	An IAllocationContext defines a shadow environment which may be associated with allocations made during a transaction.
IAllocationManager
IAllocationManagerStore	Adds capability to write and delete allocations within an IAllocationContext.
IHistoryManager	Interface for glue methods which permit the coordination of the hisory retention and deferred release mechanisms between the Journal, the IRWStrategy, and the backing IStore.
IRawTx	A hook used to support session protection by incrementing and decrementing a transaction counter within an IStore.
IRWStrategy	Defines a marker interface to be used to indicate strategies that share RW semantics such as RWStrategy and MemStrategy
IStore	The IStore interface provides persistent storage abstraction for fixed size allocations and allocation recycling.
IStreamStore	Interface for reading and writing streams on a persistence store.
IWriteCacheManager
RWStore.Options	Options understood by the RWStore.

Class Summary

AllocBlock	Bit maps for an allocator.
FixedAllocator	FixedAllocator Maintains List of AllocBlock(s)
FixedOutputStream
IPSOutputStream
PSInputStream	PSInputStream Unlike the original PSInputStream this does not incrementally read from the store but rather immediate maps the ByteBuffers to the in-memory storage.
PSOutputStream	PSOutputStream Provides stream interface direct to the low-level store.
RWStore	Storage class
RWStore.AllocationStats
RWStore.StoreCounters<T extends RWStore.StoreCounters<T>>	Striped performance counters for IRawStore access, including operations that read or write through to the underlying media.
RWWriteCacheService	Defines the WriteCacheService to be used by the RWStore.
StorageStats	Maintains stats on the RWStore allocations, useful for tuning Allocator sizes and tracking store efficiency.

Exception Summary

PhysicalAddressResolutionException

Exception thrown when a logical address maps onto a physical address which is not currently allocated.
