Class UnsynchronizedArrayBuffer<E>

java.lang.Object
  com.bigdata.relation.accesspath.AbstractUnsynchronizedArrayBuffer<E>
      com.bigdata.relation.accesspath.UnsynchronizedArrayBuffer<E>

All Implemented Interfaces:

IBuffer<E>

public class UnsynchronizedArrayBuffer<E>
extends AbstractUnsynchronizedArrayBuffer<E>

An unsynchronized buffer backed by a fixed capacity array that migrates references onto the caller's buffer (which is normally thread-safe) using IBuffer#add(int).

This implementation is NOT thread-safe.
