public abstract class AbstractIoBuffer
extends IoBuffer

A base implementation of IoBuffer. This implementation assumes that IoBuffer.buf() always returns a correct NIO ByteBuffer instance. Most implementations could extend this class and implement their own buffer management mechanism.

shrink

public final IoBuffer shrink()

Changes the capacity of this buffer so this buffer occupies as less memory as possible while retaining the position, limit and the buffer content between the position and limit.
The capacity of the buffer never becomes less than IoBuffer.minimumCapacity()
. The mark is discarded once the capacity changes.
Typically, a call to this method tries to remove as much unused bytes as possible, dividing by two the initial capacity until it can't without obtaining a new capacity lower than the IoBuffer.minimumCapacity(). For instance, if the limit is 7 and the capacity is 36, with a minimum capacity of 8, shrinking the buffer will left a capacity of 9 (we go down from 36 to 18, then from 18 to 9).

  Initial buffer :
