Class BufferRecycler

  • public final class BufferRecycler
extends java.lang.Object
    Simple helper class to encapsulate details of basic buffer recycling scheme, which helps a lot (as per profiling) for smaller encoding cases.

        protected static final java.lang.ThreadLocal<java.lang.ref.SoftReference<BufferRecycler>> _recyclerRef
        This ThreadLocal contains a SoftReference to a BufferRecycler used to provide a low-cost buffer recycling for buffers we need for encoding, decoding.
