Class ByteBufferSlicePool

java.lang.Object
  org.xnio.ByteBufferSlicePool

All Implemented Interfaces:

Pool<ByteBuffer>

public final class ByteBufferSlicePool
extends Object
implements Pool<ByteBuffer>

A buffer pooled allocator. This pool uses a series of buffer regions to back the returned pooled buffers. When the buffer is no longer needed, it should be freed back into the pool; failure to do so will cause the corresponding buffer area to be unavailable until the buffer is garbage-collected.
