如何使用 Java 互操作直接访问全局变量?
How can I access globals directly with Java interop?
所有 the documentation I see 都在谈论对象持久性。这很好,但我需要能够直接访问全局变量(比如 ^SE("Whosebug","q",34241364,"md")
)。
如何做到这一点?
是的,可以使用 Globals API,它可用于 Java eXTreme 库 (cacheextreme.jar)。参见 documentation。结束示例:
import com.intersys.globals.*;
class FetchNodes {
public static void main(String[] args) {
Connection myConn = ConnectionContext.getConnection();
try {
myConn.connect("User", "_SYSTEM", "SYS");
NodeReference nodeRef = myConn.createNodeReference("myGlobal");
// Read both existing nodes
System.out.println("Value of ^myGlobal is " + nodeRef.getString());
System.out.println("Value of ^myGlobal(\"sub1\") is " + nodeRef.getString("sub1"));
nodeRef.kill(); // delete entire array
nodeRef.close();
myConn.close();
}
catch (GlobalsException e) { System.out.println(e.getMessage()); }
} // end Main()
} // end class FetchNodes
