示例1: connectedCodeBase
import com.sun.org.omg.SendingContext.CodeBaseHelper; //导入方法依赖的package包/类
private synchronized boolean connectedCodeBase() {
if (delegate != null)
return true;
// The delegate was null, so see if the connection's
// IOR was set. If so, then we just need to connect
// it. Otherwise, there is no hope of checking the
// remote code base. That could be bug if the
// service context processing didn't occur, or it
// could be that we're talking to a foreign ORB which
// doesn't include this optional service context.
if (conn.getCodeBaseIOR() == null) {
// REVISIT. Use Merlin logging service to report that
// codebase functionality was requested but unavailable.
if (conn.getBroker().transportDebugFlag)
conn.dprint("CodeBase unavailable on connection: " + conn);
return false;
}
synchronized(iorMapLock) {
// Recheck the condition to make sure another
// thread didn't already do this while we waited
if (delegate != null)
return true;
// Do we have a reference initialized by another connection?
delegate = CachedCodeBase.iorMap.get(conn.getCodeBaseIOR());
if (delegate != null)
return true;
// Connect the delegate and update the cache
delegate = CodeBaseHelper.narrow(getObjectFromIOR());
// Save it for the benefit of other connections
CachedCodeBase.iorMap.put(conn.getCodeBaseIOR(), delegate);
}
// It's now safe to use the delegate
return true;
