 PoolChunkList<T> nextList,
 int minUsage,
 int maxUsage,
 int chunkSize)

Method Details

calculateMaxCapacity

private static int calculateMaxCapacity(int minUsage,
 int chunkSize)

Calculates the maximum capacity of a buffer that will ever be possible to allocate out of the PoolChunks that belong to the PoolChunkList with the given minUsage and maxUsage settings.

prevList

void prevList(PoolChunkList<T> prevList)

allocate

boolean allocate(PooledByteBuf<T> buf,
 int reqCapacity,
 int sizeIdx,
 PoolThreadCache threadCache)

free

boolean free(PoolChunk<T> chunk,
 long handle,
 int normCapacity,
 ByteBuffer nioBuffer)

move

private boolean move(PoolChunk<T> chunk)

move0

private boolean move0(PoolChunk<T> chunk)

Moves the PoolChunk down the PoolChunkList linked-list so it will end up in the right PoolChunkList that has the correct minUsage / maxUsage in respect to PoolChunk.usage().

add

void add(PoolChunk<T> chunk)

add0
