方法概要

方法

限定符和类型	方法和说明
ByteBuf	allocate(ByteBufAllocator alloc) Creates a new receive buffer whose capacity is probably large enough to read all inbound data and small enough not to waste its space.
int	guess() Similar to allocate(ByteBufAllocator) except that it does not allocate anything but just tells the capacity.
void	record(int actualReadBytes) Records the the actual number of read bytes in the previous read operation so that the allocator allocates the buffer with potentially more correct capacity.

allocate

ByteBuf allocate(ByteBufAllocator alloc)

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

record

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