ArrowBuf

public ArrowBuf(AtomicInteger refCnt,
                AllocationManager.BufferLedger ledger,
                UnsafeDirectLittleEndian byteBuf,
                BufferManager manager,

メソッドの詳細

bufferState

public static String bufferState(io.netty.buffer.ByteBuf buf)

reallocIfNeeded

public ArrowBuf reallocIfNeeded(int size)

refCnt

public int refCnt()

定義:

refCnt インタフェース内 io.netty.util.ReferenceCounted

checkBytes

public void checkBytes(int start,
                       int end)

Allows a function to determine whether not reading a particular string of bytes is valid.

Will throw an exception if the memory is not readable for some reason. Only doesn't something in the case that AssertionUtil.BOUNDS_CHECKING_ENABLED is true.

パラメータ:

start - The starting position of the bytes to be read.

end - The exclusive endpoint of the bytes to be read.

retain

public ArrowBuf retain(BufferAllocator target)

Create a new ArrowBuf that is associated with an alternative allocator for the purposes of memory ownership and accounting. This has no impact on the reference counting for the current ArrowBuf except in the situation where the passed in Allocator is the same as the current buffer.

This operation has no impact on the reference count of this ArrowBuf. The newly created ArrowBuf with either have a reference count of 1 (in the case that this is the first time this memory is being associated with the new allocator) or the current value of the reference count + 1 for the other AllocationManager/BufferLedger combination in the case that the provided allocator already had an association to this underlying memory.

パラメータ:

target - The target allocator to create an association with.

戻り値:

A new ArrowBuf which shares the same underlying memory as this ArrowBuf.

transferOwnership

public ArrowBuf.TransferResult transferOwnership(BufferAllocator target)

Transfer the memory accounting ownership of this ArrowBuf to another allocator. This will generate a new ArrowBuf that carries an association with the underlying memory of this ArrowBuf. If this ArrowBuf is connected to the owning BufferLedger of this memory, that memory ownership/accounting will be transferred to the target allocator. If this ArrowBuf does not currently own the memory underlying it (and is only associated with it), this does not transfer any ownership to the newly created ArrowBuf.

This operation has no impact on the reference count of this ArrowBuf. The newly created ArrowBuf with either have a reference count of 1 (in the case that this is the first time this memory is being associated with the new allocator) or the current value of the reference count for the other AllocationManager/BufferLedger combination in the case that the provided allocator already had an association to this underlying memory.

Transfers will always succeed, even if that puts the other allocator into an overlimit situation. This is possible due to the fact that the original owning allocator may have allocated this memory out of a local reservation whereas the target allocator may need to allocate new memory from a parent or RootAllocator. This operation is done in a mostly-lockless but consistent manner. As such, the overlimit==true situation could occur slightly prematurely to an actual overlimit==true condition. This is simply conservative behavior which means we may return overlimit slightly sooner than is necessary.

パラメータ:

target - The allocator to transfer ownership to.

戻り値:

A new transfer result with the impact of the transfer (whether it was overlimit) as well as the newly created ArrowBuf.
