[英]Calling a runnable method from different class
在我的项目中,我有一种从本地磁盘加载大型模型的方法。 加载模型大约需要15分钟,有时甚至更长。 我想做的是创建一个可运行的方法,该方法一次加载模型,然后从不同的类中调用此方法来执行一些代码。 实际上,我不确定如何实现这一目标,您能指导我吗? 这是简单的伪代码:
// class A has two method , load the model , and does some calculation
Class A: 1.Runnable method: LoadModel();
2.Mehtod2: distance();
// here i would like to run this programe anytime, pass some parameters and call the method "distance" in class A
Class B: 1.import Loadmodel() class and invoke distance ();
在我看来,我想创建类似于服务器但不类似于服务器的东西:)
已更新:以下代码是我到目前为止尝试过的代码。
public class load implements Runnable {
WordVectors wordVectors;
public void run() {
try {
load();
} catch (FileNotFoundException ex) {
java.util.logging.Logger.getLogger(load.class.getName()).log(Level.SEVERE, null, ex);
} catch (UnsupportedEncodingException ex) {
java.util.logging.Logger.getLogger(load.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void load() throws FileNotFoundException, UnsupportedEncodingException {
//Your display method implementation.
wordVectors = WordVectorSerializer.loadTxtVectors(new File("glove.twitter.27B.200d.txt"));
}
public double Simmiraty(String a, String b){
return wordVectors.similarity(a,b);
}
public static void main(String[] args) {
load Obj= new load ();
Obj.run();
}
}
第二类:
public class B{
public static void main(String[] args) throws Exception {
load ob =new load();
System.out.println( ob.Simmiraty("iphone", "battery"));
}
}
我不得不对上面的代码提出疑问:1.一旦加载了模型,它就会停止运行。 2.我不能从frist类中调用任何方法。
public class Load implements Runnable{
private InputStream stream;
private static final Load instance;
private WordVectors wordVectors;
static {
instance = new Load();
instance.run();
}
public static Load GetLoad(){
return instance;
}
private Load(){
if(instance != null)
throw new UnsupportedOperationException();
}
public voir run() {
if(wordVectors != null)
throw new UnsupportedOperationException();
try {
load();
} catch (Exception ex) {
Logger.getLogger(load.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void load() throws FileNotFoundException, UnsupportedEncodingException {
stream = new InputStream(new File("glove.twitter.27B.200d.txt"));
wordVectors = WordVectorSerializer.loadTxtVectors(stream,false);
}
public void interrupt(){
if(stream != null)
stream.close();
}
public double Simmiraty(String a, String b){
return wordVectors.similarity(a,b);
}
public static void main(){
Load load = GetLoad();
}
}
public class B{
public void function(){
Load load = Load.GetLoad();
}
}
