Package com.bigdata.rwstore

Interface Summary

Interface	Description
Allocator
IAllocationManager
IAllocatorSynchronization	This is a callback interface that can be used to synchronize store allocation structures.
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.
IWriteCacheManager
RWStore.Options	Options understood by the RWStore.

Class Summary

Class	Description
AllocBlock	Bit maps for an allocator.
FixedAllocator	FixedAllocator Maintains List of AllocBlock(s)
FixedOutputStream
MetabitsUtil	A utility class to explicitly change the metabits storage to allow for compatibility with previous versions.
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.DeleteBlockStats	Simple class to collect up DeleteBlockStats and returned by checkDeleteBlocks, called from DumpJournal.
RWStore.RWStoreState
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.
TestAll	Runs all tests for all journal implementations.
TestAllocBits
TestRWJournal	Test suite for BufferMode.DiskRW journals.
TestRWJournal.TestInterrupts	Test suite integration for AbstractInterruptsTestCase.
TestRWJournal.TestMRMW	Test suite integration for AbstractMRMWTestCase.
TestRWJournal.TestMROW	Test suite integration for AbstractMROWTestCase.
TestRWJournal.TestRawStore	Test suite integration for AbstractRestartSafeTestCase.

Exception Summary
