- * The class provides reuse of ByteBuffers.
- * It is supposed that all requested buffers have the same size for a long period of time.
- * That is why there is no any logic splitting buffers into different buckets (by size). It's unnecessary.
- *
- * At the same moment it is allowed to change requested buffers size (all smaller buffers will be discarded).
- * It may be needed for example, if after rehandshaking netPacketBufferSize was changed.
