示例1: readFromChannel
import java.nio.channels.ByteChannel; //導入方法依賴的package包/類
protected void readFromChannel(ByteChannel sc) {
int len = 0;
ByteBuffer inputBuffer = inBuf; // save a local reference just in case it gets nulled out.
// TODO: probably need some type of synchronization on the input
// buffer because it gets nulled out in closeComplete due to
// timeout and then can potentially cause a crash here.
if (sc.isOpen() && state != State.CLOSED && inputBuffer != null) {
try {
len = sc.read(inputBuffer);
} catch (IOException e) {
LOG.trace("readFromChannel: exception on read on port " + localPort, e);
len = -1;
}
if (LOG.isTraceEnabled()) {
LOG.trace("readFromChannel(" + len + " bytes) from port " + localPort);
}
if (len >= 0) {
addToBuffer(bytes, len);
inBuf.clear();
} else if (len < 0) {
closeComplete();
}
} else if (LOG.isTraceEnabled()) {
LOG.trace(MessageFormat.format("readFromChannel: Looks like connection is closed for port {0}, sc.isOpen()={1}, state={2}, inputBuffer={3}", localPort, sc.isOpen(), state, inputBuffer));
}
}
