示例1: implCloseChannel
import java.nio.channels.FileLock; //導入方法依賴的package包/類
protected void implCloseChannel() throws IOException {
// Release and invalidate any locks that we still hold
if (fileLockTable != null) {
for (FileLock fl: fileLockTable.removeAll()) {
synchronized (fl) {
if (fl.isValid()) {
nd.release(fd, fl.position(), fl.size());
((FileLockImpl)fl).invalidate();
}
}
}
}
// signal any threads blocked on this channel
threads.signalAndWait();
if (parent != null) {
// Close the fd via the parent stream's close method. The parent
// will reinvoke our close method, which is defined in the
// superclass AbstractInterruptibleChannel, but the isOpen logic in
// that method will prevent this method from being reinvoked.
//
((java.io.Closeable)parent).close();
} else {
nd.close(fd);
}
}
