接口 AdaptiveBufAllocator.Handle

封闭类:

AdaptiveBufAllocator

public static interface AdaptiveBufAllocator.Handle

方法概要

限定符和类型	方法和说明
ByteBufferCollector	allocate() Creates a new buffer whose capacity is probably large enough to write all outbound data and small enough not to waste its space.
ByteBufferCollector	allocateByRecyclers() Gets a buffer from recyclers whose capacity is probably large enough to write all outbound data and small enough not to waste its space, recycling is needed.
int	guess() Similar to allocate() except that it does not allocate anything but just tells the capacity.
void	record(int actualWroteBytes) Records the the actual number of wrote bytes in the previous write operation so that the allocator allocates the buffer with potentially more correct capacity.

方法详细资料

allocate

ByteBufferCollector allocate()

Creates a new buffer whose capacity is probably large enough to write all outbound data and small enough not to waste its space.

allocateByRecyclers

ByteBufferCollector allocateByRecyclers()

Gets a buffer from recyclers whose capacity is probably large enough to write all outbound data and small enough not to waste its space, recycling is needed.

guess

int guess()

Similar to allocate() except that it does not allocate anything but just tells the capacity.

record

void record(int actualWroteBytes)

Records the the actual number of wrote bytes in the previous write operation so that the allocator allocates the buffer with potentially more correct capacity.

参数:

actualWroteBytes - the actual number of wrote bytes in the previous allocate operation
