java - 如何创建 JsArray 作为 JavaScriptObject

Question

我需要一个包含 JsArray 和 String 的 JavaScriptObject。该 JsArray 应该具有像普通 GWT JsArray 一样的所有功能，如 push()、pop() 等。但如何创建它呢？我已经创建了一些我想要的东西，但它不起作用

public class Tour extends JavaScriptObject {

protected Tour() {
    // TODO Auto-generated constructor stub
}

public static Tour getInstance(){
    return JavaScriptObject.createArray().cast();
}

public final native void setTourName(String name)/*-{
    this.name = name;
}-*/;

public final native String getTourName()/*-{
    return this.name;
}-*/;

public final native JsArray<JavaScriptObject> getArray() /*-{
    return this.array;
}-*/;

public final native void setJsArray(JsArray<JavaScriptObject> array)/*-{
    this.array = array;
}-*/;

public final native void push(JavaScriptObject obj)/*-{
    this.array.push(obj);
}-*/;

public final native int getLength()/*-{
    this.array.length;
}-*/;

}

public class Tour extends JavaScriptObject {

    protected Tour() {
    }

    public static Tour getInstance() {
        return getInstance(null, null);
    }

    public static Tour getInstance(String name) {
        return getInstance(name, null);
    }

    public static native Tour getInstance(String name, JsArray<JavaScriptObject> array) /*-{
        return {
            name : name,
            array : array || []
        };
    }-*/;

    // the rest of your class stays untouched...

    public final native void setTourName(String name)/*-{
        this.name = name;
    }-*/;

    public final native String getTourName()/*-{
        return this.name;
    }-*/;

    public final native JsArray<JavaScriptObject> getArray() /*-{
        return this.array;
    }-*/;

    public final native void setJsArray(JsArray<JavaScriptObject> array)/*-{
        this.array = array;
    }-*/;

    public final native void push(JavaScriptObject obj)/*-{
        this.array.push(obj);
    }-*/;

    public final native int getLength()/*-{
        this.array.length;
    }-*/;
}
