Examples of ByteBufferPool

com.facebook.presto.jdbc.internal.jetty.io.ByteBufferPool

A {@link ByteBuffer} pool.
Acquired buffers may be {@link #release(ByteBuffer) released} but they do not need to;if they are released, they may be recycled and reused, otherwise they will be garbage collected as usual.
