Class IoUringAdaptiveBufferRingAllocator

java.lang.Object

io.netty.channel.uring.IoUringAdaptiveBufferRingAllocator

All Implemented Interfaces:

IoUringBufferRingAllocator

public final class IoUringAdaptiveBufferRingAllocator
extends java.lang.Object
implements IoUringBufferRingAllocator

IoUringBufferRingAllocator implementation which uses an adaptive strategy to allocate buffers, which will decrease / increase the buffer size depending on if the allocated buffers were completely used or not before.

IoUringAdaptiveBufferRingAllocator

public IoUringAdaptiveBufferRingAllocator()

IoUringAdaptiveBufferRingAllocator

public IoUringAdaptiveBufferRingAllocator(ByteBufAllocator allocator)

Creates new instance.

Parameters:

allocator - the ByteBufAllocator to use.

IoUringAdaptiveBufferRingAllocator

public IoUringAdaptiveBufferRingAllocator(ByteBufAllocator allocator,
                                          int minimum,
                                          int initial,
                                          int maximum)

Creates new instance.

Parameters:

allocator - the ByteBufAllocator to use for the allocations

minimum - the inclusive lower bound of the expected buffer size

initial - the initial buffer size when no feed back was received

maximum - the inclusive upper bound of the expected buffer size

Method Detail

allocate

public ByteBuf allocate()

Description copied from interface: IoUringBufferRingAllocator

Creates a new receive buffer to use by the buffer ring. The returned ByteBuf must be direct.

Specified by:

allocate in interface IoUringBufferRingAllocator

lastBytesRead

public void lastBytesRead(int attempted,
                          int actual)

Description copied from interface: IoUringBufferRingAllocator

Set the bytes that have been read for the last read operation that was full-filled out of the buffer ring.

Specified by:

lastBytesRead in interface IoUringBufferRingAllocator

Parameters:

attempted - the attempted bytes to read.

actual - the number of bytes that could be read.
