Uses of IAllocationContext in com.bigdata.rwstore

Methods in com.bigdata.rwstore that return IAllocationContext

Modifier and Type	Method and Description
IAllocationContext	RWStore.newAllocationContext(boolean isolated)
IAllocationContext	IAllocationManager.newAllocationContext(boolean isolated) Creates a context to be used to isolate updates to within the context until it is released to the parent environment.

Methods in com.bigdata.rwstore with parameters of type IAllocationContext

Modifier and Type	Method and Description
void	FixedAllocator.abortAllocationContext(IAllocationContext context, RWWriteCacheService writeCacheService) Unwinds the allocations made within the context and clears the write cache of any associated data
void	RWStore.abortContext(IAllocationContext context) The ContextAllocation object manages a freeList of associated allocators and an overall list of allocators.
void	IAllocationManager.abortContext(IAllocationContext context) Indicates that the allocation context will no longer be used and that the allocations made within the context should be discarded.
long	RWStore.alloc(byte[] buf, int size, IAllocationContext context) Called by PSOutputStream to make to actual allocation or directly by lower level API clients.
long	IStore.alloc(byte[] buf, int size, IAllocationContext context) Writes data on the store.
int	RWStore.alloc(int size, IAllocationContext context) Core allocation method.
int	Allocator.alloc(RWStore store, int size, IAllocationContext context)
int	FixedAllocator.alloc(RWStore store, int size, IAllocationContext context) The introduction of IAllocationContexts has added some complexity to the older concept of a free list.
boolean	Allocator.canImmediatelyFree(int addr, int size, IAllocationContext context)
boolean	FixedAllocator.canImmediatelyFree(int addr, int size, IAllocationContext context) If the context is this allocators context AND it is not in the commit bits then we can immediately free.
void	RWStore.detachContext(IAllocationContext context) Indicates that the allocation context will no longer be used, but that the allocations made within the context should be preserved.
void	IAllocationManager.detachContext(IAllocationContext context) Indicates that the allocation context will no longer be used, but that the allocations made within the context should be preserved.
void	RWStore.free(long laddr, int sze, IAllocationContext context) free
static PSOutputStream	PSOutputStream.getNew(IStore store, int maxAlloc, IAllocationContext context)
IPSOutputStream	RWStore.getOutputStream(IAllocationContext context)
