Class BufferRecycler

java.lang.Object  extended by com.fasterxml.jackson.core.util.BufferRecycler

public class BufferRecycler
extends Object

This is a small utility class, whose main functionality is to allow simple reuse of raw byte/char buffers. It is usually used through ThreadLocal member of the owning class pointing to instance of this class through a SoftReference. The end result is a low-overhead GC-cleanable recycling: hopefully ideal for use by stream readers.
