The Jetty AbstractNIOConnector.java source code/** * */ package org.mortbay.jetty.nio; import org.mortbay.io.Buffer; import org.mortbay.io.nio.NIOBuffer; import org.mortbay.jetty.AbstractConnector; /* ------------------------------------------------------------ */ /** * @author gregw * */ public abstract class AbstractNIOConnector extends AbstractConnector implements NIOConnector { private boolean _useDirectBuffers=true; /* ------------------------------------------------------------------------------- */ public boolean getUseDirectBuffers() { return _useDirectBuffers; } /* ------------------------------------------------------------------------------- */ /** * @param direct If True (the default), the connector can use NIO direct buffers. * Some JVMs have memory management issues (bugs) with direct buffers. */ public void setUseDirectBuffers(boolean direct) { _useDirectBuffers=direct; } /* ------------------------------------------------------------------------------- */ protected Buffer newBuffer(int size) { // TODO // Header buffers always byte array buffers (efficiency of random access) // There are lots of things to consider here... DIRECT buffers are faster to // send but more expensive to build and access! so we have choices to make... // + headers are constructed bit by bit and parsed bit by bit, so INDiRECT looks // good for them. // + but will a gather write of an INDIRECT header with a DIRECT body be any good? // this needs to be benchmarked. // + Will it be possible to get a DIRECT header buffer just for the gather writes of // content from file mapped buffers? // + Are gather writes worth the effort? Maybe they will work well with two INDIRECT // buffers being copied into a single kernel buffer? // Buffer buf = null; if (size==getHeaderBufferSize()) buf= new NIOBuffer(size, NIOBuffer.INDIRECT); else buf = new NIOBuffer(size, _useDirectBuffers?NIOBuffer.DIRECT:NIOBuffer.INDIRECT); return buf; } } Other Jetty examples (source code examples)Here is a short list of links related to this Jetty AbstractNIOConnector.java source code file: |
